Brewing With Style

The styles popularized by Belgian (and one Dutch) Trappist breweries and the secular abbey breweries are single/blonde, dubbel, tripel and quadrupel/strong dark. They may be identified by the old Belgian numerical degree system (Rochefort 8), style (Westmalle Tripel) or unique brand (Chimay Grande Réserve). Single/blonde (5 to 6.5 percent ABV) and tripel (8 to 9.5 percent) are gold to dark gold in color. Dubbel (6 to 7 percent) and quadrupel/strong dark (10 to 12 percent ) are deep copper to brownish-red. Pale beers will be grouped together, as will the dark, as they can be crafted with similar ingredients.

The similarities among them include raw materials, as well as technique and brewing philosophy. Abbey/Trappist beers are highly attenuated and never heavy or cloying, but retain a touch of sweetness. Adjuncts are universally used, usually sugar, but sometimes also wheat or maize. The beers are almost exclusively presented as bottle-conditioned products and often are rambunctiously effervescent. Forced carbonation is convenient, but it is dismissive of the nuance that the yeasts impart over time. Both Wyeast and White Labs offer strains culled from abbey and Trappist breweries. They are indispensable.

Great Grains

The favored base malt is the delicately flavored pilsner variety. It lends the high fermentability and lean body common to these beers. Pale brews will need very little augmentation with specialty malts, if any. I prefer a simple grist of pilsner and Vienna, in a 3:1 ratio. Munich malt at 10 to 20 percent will add a backdrop of maltiness. If you feel the need to add specialty malts, stick with Carapils, light crystal or Caravienne, at 5 percent or less to minimize caramel character. Malted wheat could be used to add some creaminess and heading. Mash at 148 to 150 degrees F.

For dubbels, quads and strong darks, the grain bill is a bit more complicated, but also more malleable. Because the beers are still quite light in body in spite of the color, the selection of malt is even more critical. The necessary specialty malts should be used judiciously to get maximum color and flavor characteristics without bogging down the beer. Combinations of pilsner, Vienna and Munich malts as a base are an excellent starting point. I have used 100 percent Vienna malt or a 3:1 ratio of pilsner to Munich with great results.

Sticking with the dark brews, Continental European specialty malts, used at 10 to 15 percent of the grist, will contribute loads of the signature flavors and aromas. The “Cara” family is very diverse, ranging from 5 to 120 degrees Lovibond, imparting sweet caramel, toasted malt, toffee, rum, raisin and fig flavors and aromas, depending on the color. Aromatic malts offer intense malty character. Small amounts of special B (very dark crystal) and chocolate malt add plenty of color, but also extra depth. For proper attenuation, mash at 146 to 149 degrees F.

Most homebrew shops stock French and/or Belgian malts, designed specifically for abbey and Trappist beers. As German malt is very similar to French or Belgian in variety and specifications, it is essentially interchangeable. Adjunct grains such as flaked wheat or maize are commonly used in Belgium, and very traditional.

Extract brewers have at their disposal all the ingredients needed to make these heavenly brews. Extra light and light extracts made from pilsner malt provide the same foundation as grain brewers. Munich malt and wheat malt extracts can be used in place of up to 20 percent of the light malt extract. Avoid adjunct grains unless you do partial mashes, and then ensure that there is enough diastatic power included in the grist (See the Homebrewing column in the March 2013 issue for details). The inclusion of specialty grains and sugars is no different from that of all-grain brewers. And it goes without saying that hop schedules and yeast performance are also identical to more-advanced brewing techniques.

Adjunct Sugar

Sugar is a critical component of abbey and Trappist beer. It serves to boost gravity and fermentables, but, more importantly, keeps body relatively light without compromising complexity and richness.

Homebrew shops stock Belgian candi sugar in three forms: syrup, soft (similar to brown sugar) and rock. They come in several color grades, from virtually transparent (no color contribution) to very dark (180 degrees L). With color comes more pronounced and complex flavor and aroma. The lightest will be mostly neutral, with increasing caramel, raisin, date, toffee, vanilla, molasses and chocolate notes as the color deepens. The darkest one available includes some date sugar in the formulation. Some syrups are even laced with spices, botanicals and flavorings. Different forms will contribute to gravity differently due to moisture content. My rule of thumb is to start with a pound per 5 gallons of wort, added during the boil.

Unrefined sugars, such as demerara, turbinado, jaggery, piloncillo and date sugar, are superb choices. Plain dextrose (corn sugar) and glucose (table or cane sugar) can be used, but will only contribute gravity and little more.

Varietal honey can be matched impeccably with a personalized recipe. Try buckwheat honey in a dubbel or quad, clover or orange blossom in a tripel, and sourwood or tupelo in a blonde. Remember that the aromatics in honey are quite volatile, so add it at knockout or at the end of the boil.

Hops and Spices

None of these styles particularly feature hops but, of course, warrant some bitterness for balance, with IBU-to-gravity ratio between 0.35 and 0.5. Flavor and aroma additions are also reserved, but blondes and tripels support late additions well. Styrian Goldings, Kent Goldings, Saaz and German nobles are the more traditional cultivars used, but Perle, Strisselspalt, Challenger and Target also fit the bill. I like the earthy, floral and subtle citrus notes of Styrian and Kent Goldings and Czech Saaz for flavor and aroma, especially in pale brews. Perle and Goldings are my choice for dark brews.

Spices are used as an accent by some brewers. Coriander or grains of paradise in very reserved amounts would enhance any of the styles, and spices such as star anise would fit well with a darker brew. Add them late in the boil and keep the measure to a minimum, under an ounce per 5 gallons.

Yeast

Belgian beers are immediately recognizable and often defined by the conspicuous yeast contribution. There are enough different strains from Trappist and secular abbey breweries (Rochefort, Westmalle, Orval, Achouffe and Chimay) available to fit any personal preference. Most ferment without adverse effect into the mid- and upper-70 degrees Fahrenheit or beyond.

In fact, yeast expression will change from the low to high end of the fermentation range. Westmalle yeast is used by three Trappist breweries, each of which uses different conditions and schedules to get its desired, unique product. Orval uses two strains of Brettanomyces in addition to its house yeast, which used alone will still make an excellent blonde. As always, investigate the specs of your chosen yeast carefully before brewing.

Belgian strains tend to attenuate slightly more on average, but grain selection, mash temperature and sugar additions are equally important to achieving the proper mouthfeel and attenuation, often as high as 80 to 90 percent. They are pretty determined rascals and will stand up to extended bottle-conditioning and cellaring. Selected for this very characteristic, they will metamorphose and dry out significantly over time.

The yeasts are famous for their aromatic and flavor contributions, lending clove and phenolics, fruity notes (apple, cherry, pear and peach), spiciness (vanilla, cinnamon and pepper), and even banana and bubblegum depending on the strain. Fermentation temperature will determine which of these are suppressed or accented.

Varietal hop development has seen a vigorous upswing recently, while classic cultivars are just as popular and noble as ever. Brewers are finding creative ways to showcase them all. This wealth of variety and expression is pure gold to homebrewers, if sometimes a bit overwhelming. Skillful, expert hopping is not as daunting as it may seem, and an understanding of a few basic concepts is all one needs to fine tune that recipe—be it balance, bombast or something in between.

Hop Utilization

Most recipes require a certain level of bitterness, as measured in International Bittering Units, or IBUs. Attaining this level requires proper hop utilization, extracting the bittering alpha acids (AA) throughout the duration of the boil. To calculate IBU, all that’s needed is an IBU equation (there are several available) and a utilization chart that relates kettle gravity to boiling time. Sure, you’ll need a little mathematical moxie, but plugging in the variables will become second nature.

My advice is to pick one equation and one chart from a reliable brewing resource and stick with it. Then, critically evaluate your finished beer and adjust as needed. Find an equation that accounts for pellet vs. whole hops. A full rolling boil is the surest and best way to get consistency and adequate extraction from hops.

A hydrometer or refractometer will become your best friend on brew day, as it is needed to monitor gravity during a session. All of this will require some attention to detail and practice, but the results are well worth it.

Recipes will occasionally give bittering additions in AAU, or alpha acid units, which is the weight in ounces of hops multiplied by alpha acid percent. This is used in fairly standardized recipes as a shortcut and assumes that all other parameters will be met while brewing.

There are some considerations to make between using whole or pellet hops. Some brewers swear by whole hops as a superior contributor to flavor and aroma. They have a lower utilization factor. Pellets, macerated and extruded, are more processed. They are easier to store, and they separate from wort in the kettle better and provide superior utilization. Some brewers use a hop bag with whole hops in the kettle, but I do not recommend it since it can give inconsistent and/or poor hop extraction.

Building a Schedule

Putting together a coherent and effective hop schedule is artistic brewing at its best. The three common additions are known as bittering, flavoring and aromatic. Hop types are generally labeled by their best application: bittering (high AA, harsher flavors), aroma (subtle, pleasant flavor and aroma, low AA) or dual-purpose hops (fairly high AA, but still excellent contributors to flavor/aroma). There dozens of each and, in fact, quite a few new recent cultivars from the U.S., England, Germany and New Zealand. Hop vendors and homebrew shops offer full descriptions of each. Those specs are an invaluable resource for building hop schedules. Many of these new hop varieties are a result of the very influential and robust North American brewing scene.

Flavor components are best extracted at 20 to 40 minutes in the boil, and aromatics from 20 minutes to flame knockout. Boiling drives off aromatics over time, so choose your timing carefully: the later, the better. A “hot stand,” letting the wort steep without chilling for 30 to 40 minutes post-boil, will also help intensify late kettle additions.

If you are seeking to clone a schedule of your favorite commercial beer, check if the brewery offers some clues on its website.

First Wort Hopping

First wort hopping is an old German method used to smooth out the hop profile and marginally increase hop utilization. It has gotten the attention of modern brewers and is an excellent option for homebrewers. Hops (up to a third of the overall measure) are added to kettle while it is being filled, exposing the hops to hot, but not boiling, wort. This prolonged exposure seems to seal and enhance the more delicate flavors and aroma, while at the same time increasing AA extraction and softening the harsher, hoppy edges.

First wort hopping will increase utilization by about 10 percent.

Dual-purpose varieties are tailor-made for this method since they offer excellent flavor/aroma qualities as well as decent AA content. First wort hopping is wise for any beer that favors later hop additions, be it a modern hoppy barrage or something more subdued. Whole hop flowers are extraordinarily suited for FWH.

Dry Hopping

Dry hopping, originally used to help preserve aging cask beer, had the side benefit of imparting wonderful hop aromatics. It is now largely used for the aromatic effect, and seldom are those hops in contact with the beer for more than a few days. It is done at cellar or fermentation temperatures, and all fleeting volatiles are retained. Dry hopping is best employed late in the fermentation stage or in the keg/cask used for serving.

Brewers who opt for the fermenter method have a couple of options. Hops can be added to the primary fermenter as activity wanes, left for a few days and then racked to the secondary. Use pellets in carboy primaries and either pellets or whole cones in a bucket primary. Alternatively, the hops can be added to the secondary fermenter during racking. They will eventually sink to bottom of the carboy, out of the way of the racking cane during transfer to bottling bucket or keg/cask. Expect a little hazy carryover during the rack.

Since most homebrewers keg rather than cask their beer for serving, 5-gallon corny kegs offer a superb chance to duplicate the cask method. Whole hops are preferred to pellets. Stuffed into a muslin or hop sack, they can be suspended with a string in the keg or the “pillow” allowed to sink to the bottom. The flavor will change dramatically over a few days as the scrumptious soluble compounds are leached from the cones. There is no need to pasteurize the hops used for dry-hopping.

SMaSH and Single Hop Brewing

There is no better way to investigate the footprint of a single-hop variety than with SMaSH (Single Malt and Single Hop) brewing. Dual-purpose hops fairly scream for the practicality and simplicity of this strategy, especially if you are a minimalist brewer, as I am. There are so many American hops available now that a virtually endless array of beers can be crafted. Classic noble hops are excellent candidates for German or Czech SMaSH brews. Explore English dual-purpose hops, such as Bramling Cross, First Gold, Pioneer or Progress, and one can’t go wrong with the classic East Kent Goldings. Once a recipe has been honed, iadjustments are easier to make.

Body and mouthfeel can be adjusted by altering mash temperature, color and caramelization, and intensified by prolonging the boil. With some creative thought, you’ll be amazed at the number of beers that can be made this way with English pale ale, Pilsner, Vienna or Munich malts and two to five single-cultivar hop additions. If single-malt brewing isn’t your thing, add some character malt to the grist, but keep the grain bill simple to tease out the hop character more distinctly.

Hop Bursting

The popularity of hop-forward beers has brought the concept of hop bursting to the forefront. If you’ve ever wondered how brewers get that sublimely round bitterness and enormous flavor and aroma into their beer, it is probably via hop bursting. The method entails adding nearly all hops within the last 30 minutes of the boil, including the bittering hops. This will preserve all ephemeral flavor and aroma, and softly contour the bitterness. It requires at least twice the normal amount for bittering, and even more for subsequent doses.

Boil for 30 minutes to get good kettle interactions and then start the hop schedule over the next 30 minutes. An addition every 5 or 10 minutes through kettle knockout followed by a “hot stand” and dry hopping will furnish an impressive burst. I think this method works impeccably for regular IPAs, offering an intense hop profile with less potential palate fatigue.

No matter what kind of beer is on your brewing docket, there is always a way to make it better. These simple strategies should help get you there. From helles to hop bombs, all will benefit from a deft hoppy hand.

When thinking about great beer cities in the United States, Portland, Denver, Seattle and San Francisco might come to mind. But New York? Probably not. At least not yet.

At the forefront of mixology culture and the setting of more than a few wine bars, New York has lacked in local brews. That’s not to say contributions from institutions like Brooklyn Brewery, Chelsea Brewing or the Heartland chain haven’t had an impact on the local scene, but for a long time they were the only names in the game.

Now, a spate of dedicated homebrewers are opening craft and nano breweries throughout the city, particularly in the outer boroughs. These brewers are so committed to improving New York City’s beer landscape that many fit brewing into the off hours from their full-time jobs.

Paul Sciara had been brewing with his brothers John and Jeff for years. Since the response to their beers was so positive, they decided to launch City Island Beer Co. in the Bronx. Their flagship pale ale is contract-brewed at Paper City Brewery in Holyoke, MA, while the brothers look for space for a brewery in their home borough. “We’re a local brand,” says Sciara, who works as an engineer by day. “Craft beer is a big growth area in the city. … It’s more exciting than you can imagine.”

Queens was a veritable brewing desert until 2012 when three breweries opened in the borough. Ethan Long and Marcus Burnett, friends and longtime homebrewing partners, led the trend with Rockaway Brewing Co. As California transplants, they felt New York City needed more local beer. “If Portland can have [more than 70] breweries, New York City can have more than a handful,” Long says. He works for a scenery fabrication operation and Burnett works as a cinematographer during the day.

Though the brewery takes its name from the Rockaway neighborhood, Long and Burnett brew out of Long Island City. Being a part of the brewing trend is “pretty amazing,” Long said. “I was calling it a small wave, but it’s really like a tsunami.”

Bridge and Tunnel Brewery opened in Maspeth, Queens, in late 2012. It’s a one-man nano brewery by homebrewer Rich Castagna. He manages to fit in brewing between family obligations (he has a wife and three kids) and a full-time job arranging exports for a shipping company.

In December Rich Buceta opened SingleCut Beersmiths in Astoria, Queens. Buceta began homebrewing in the ’90s. He aims for SingleCut to be a “true local brewery.”

With a focus mainly on lagers, Buceta takes inspiration from guitar and rock legends, such as Cult guitarist Billy Duffy, who has two of SingleCut’s IPAs named for him. The 19-33 Queens Lagrr is a shout-out to the year Prohibition ended. “I hold the standard very high,” he says. “My heroes are the brewers on the West Coast and in Vermont. Opening a local brewery isn’t good enough. It has to be great.”

This trend of homebrewers going pro in New York City shows no signs of stopping in 2013.

EST Brewing will debut in mid-2013 at the Brooklyn Flea’s Smorgasbar section of its summer food market Smorgasburg. EST is the brainchild of Erica Shea and Stephen Valand, owners of a successful homebrewing kit business, the Brooklyn Brew Shop, along with their production manager, Tim Evans.

“It’s the coolest thing in the world to realize that you can do this at home and serve your friends something delicious,” Shea says. “We like re-creating that experience for people, but we also really like drinking our beer.” EST’s beers will reflect food and flavors of the seasons, the first being a jalapeño saison.

Slated to launch in autumn 2013 is Finback Brewery, started by homebrewers Basil Lee and Kevin Stafford. Lee and Stafford are closing in on a location for their 20-barrel system. Meanwhile, the pair has been bringing beers to homebrewing events. “The homebrewing community is pretty awesome in New York City,” Lee says. “Everyone’s excited and fundamentally interested in making the beer.”

BOULDER, CO—The American Homebrewers Association (AHA) released the results of its fourth annual Homebrew Supply Shop Survey, detailing the current state of the home beer and wine supply retail industry. The results indicate that, on the whole, shops are thriving as they cater to the growing community of homebrewing enthusiasts.

Reviewing data from 275 shops spanning 47 states—a 32 percent increase in participants from last year’s survey—the survey found that on average, participants saw gross revenue increase by 26 percent in 2012. For shops that primarily sell homebrew supplies, gross revenue increased on average by 29 percent. This is 2 percent higher than last year’s results and 10 percent higher than results from the first AHA supply shop survey conducted in 2009.

“As homebrewing continues to grow, retail shops are responding accordingly, satisfying the needs of their increasing customer base,” said Gary Glass, director, American Homebrewers Association. “Homebrew supply shops serve as the heart of local homebrewing communities. The success of a local shop will ensure a thriving community of homebrewers.”

Additional highlights from the survey include:

• Homebrew Beginners: The majority of shops (80 percent) experienced increased sales of beginner homebrew equipment kits, signifying a considerable boost in interest in the hobby. The largest segment of people buying the beginner kits were individuals 30 to 39 years old.

• New Lease on Brewing: In 2013, 43 percent of responding shops said they have been open for three years or less, up from 34 percent in 2012, indicating considerable growth in new shop openings.

• Beer vs. Wine: Sales of beer ingredients outpaced wine ingredients among home beverage supply retailers, with an average of 35 percent of retail revenue coming from beer ingredients versus 21 percent from wine ingredients.

The full report contains additional information on customer demographics, marketing and sales. Results demonstrated significant advancement in several areas considered by the AHA, including gross revenue, store openings and beginner equipment sales, indicating a growth in the industry. The AHA conducts this survey every year to provide homebrewers and supply retailers with the latest industry information.

The more elusive, though, are German Kölsch and altbier of the Rhine Valley. Not only are they quite different from all other German brews, but each is also distinctive enough to be the calling card of a city, and it is this provenance that sets them apart.

The two cities that they call home, Köln (Cologne) and Düsseldorf, are separated by barely 20 miles, but the cultural differences and rivalries are great. Ironically, the two beers share some essential brewing methods, and they are both something of a challenge to make well. If you’re up to the task, they can be brewed by following a few unique and rigid guidelines. Beyond that, the possibilities are actually rather broad if you want to make some interesting and very personalized hybrids, German-accented or otherwise.

Hybrid Defined

Kölsch and altbier combine top fermentation (typical of ales) and cold conditioning (typical of lagers). I love the self-explanatory, seemingly oxymoronic designation obergaerige lagerbier (top-fermented lager beer) that is often used to refer to these two indigenous German brews.

The yeasts used for both are specialized, selected over centuries to accommodate the environs and critical to their brewing. Tailored to the mild climate of the Lower Rhine Valley, Kölsch and altbier yeast work most comfortably at 55 to 65 degrees F, conditions that suppress the fruity esters and spicy notes associated with the ales of Britain and the other top-fermented brews of Europe.

Lagering is done at a modest 40 degrees F for about four to six weeks, warmer than the near-freezing condition of bottom-fermented lagerbiers. The character of the yeast and the lagering method suggest that these strains have been culled from bottom fermenters but adapted to slightly higher temperatures (much like the California Lager yeast used to make California common).

Beyond that, brewing Kölsch and altbier is merely a matter of selecting a proper grain bill and hop schedule, and selecting one of the several yeasts available to craft your homebrew. The stickiest requirement is ensuring that the yeast is comfortable during fermentation, always a consideration, but more so with these.

Brewing Kölsch

Kölschbier is the lighter of the two, always a shade of gold. This means, of course, that it is made primarily with Continental pilsner malt, and usually that malt alone. A simple bill of pilsner malt from Germany or Belgium, mashed for high fermentability, will produce classic Kölsch. Traditional wort strength is OG 1044 to 1048. I like to mash at about 148 degrees F, leaving little residual dextrine.

Malted wheat is not a stranger to Kölschbier grist, and it will add a bit of mouthfeel and depth. A touch of Vienna malt, up to 15 percent, will also provide extra character and deeper gold color.

Should you opt for a more dextrinous brew, mash into the low 150s, or use about 5 percent dextrine malt in the grist. Caramel flavors are not part of the Kölsch profile, so stick with dextrine malt over light caramel/crystal varieties. If you use American two-row malt, light specialty or toasted malt addition is advised. Extract brewers should use the lightest malt extract available, either on its own or with a touch of wheat or Munich malt extract.

Hop rates in the low- to mid-20s provide the perfect complement to the elegant malt character. Minimal aroma hops are traditional and, in a beer this delicate, even a meager aromatic addition will be noticeable. As one who loves to make classic versions of beers, I usually stick with German low-alpha-acid varieties such as Tettnang, Hallertau, or Hersbrucker, as well as Czech Saaz for aroma. American hops with German pedigree are also acceptable.

There are several Kölsch yeasts available from both Wyeast and White Labs; all of them are highly attenuative and will serve to retain the feathery malt character that you have so ardently striven to achieve. I have found that some lend an herbal character, enhancing the hops, while others provide a soft malty and even vinous note. As always, consult the vendor specs online.
