A yeast strain originating from the McEwans's brewery, Wyeast's Scottish Ale yeast is used classically in all Scottish style ales. However, it is a highly versatile yeast with a good alcohol tolerance and high flocculations, making it suitable for beers of just about any style. Indeed, many brewers (including a few of us here at Great Fermentations) routinely use this as a house strain. Malt character is allowed to shine when this yeast is used. It has an incredible temperature range and can ferment at any temperature between 55-75°F. A cleaner, less estery profile will be created at lower temperatures, and more ester production will occur at higher temperatures. Try this yeast on the suggested styles, or in just about anything you feel like!

An excellent choice in the production of stouts and other dark beers, Wyeast's Irish Ale strain is the classic strain from the Guiness Brewery. Although it is most popularly used in stouts, it can produce a number of wonderful beers and can be used to great effect with high gravity worts. At lower temperatures this yeast is crisp and dry, with an underlying fruitiness that becomes more evident and estery with higher fermentation temperatures.

Wyeast's West Yorkshire strain of yeast is known for balance. While producing the characteristic British profile full of fruity esters with some nuttiness, its dry finish keeps these notes in check, making for beers that are delicious and quite pleasing to the palette. It has been said by some to have a slight mineral note that is common in some English and British style beers. Cask-conditioned beers and traditional British beers will benefit from this yeast, as the flavors produced by the yeast lend to the fullness of such styles. A great choice for English pales, bitters, browns and stouts.
Beer Styles: English IPA, Extra Special/Strong Bitter (English Pale Ale), Oatmeal Stout, Southern English Brown, Special/Best/Premium Bitter, Standard/Ordinary Bitter, Sweet Stout.
Bohemian Lager is one of our favorite lager strains. It is malty with a crisp bite to it that serves well in the production of a wide range of lagers, from light European and American style Pilsners to rich, malty Bock beers. This strain exhibits a slightly pronounced ester profile. It does very well on all lagers at its recommended temperature range, but it can also be fermented warmer to produce California Common beers and other styles as well. Wyeast recommends utilizing a diacetyl rest with this strain in order to produce as clean a beer as possible.
Beer Styles: Baltic Porter, Bière de Garde, Bohemian Pilsner, Classic American Pilsner, Dark American Lager, Doppelbock, Dortmunder Export, Eisbock, German Pilsner (Pils), Maibock/Helles Bock, Munich Dunkel, Munich Helles, Oktoberfest/Märzen, Schwarzbier (Black Beer), Traditional Bock, Vienna Lager.
Wyeast's Bavarian Lager strain produces malty, rich beers, and as such is a great choice for a number of malt-forward German lagers. This yeast produces rich, malt-forward beers that clear and attenuate well. Many brewers use Bavarian Lager yeast for bock beers, Munich dunkels and Oktoberfest/Märzens with astounding results. While Wyeast recommends a diacetyl rest after fermentation, many brewers report that this yeast performs a very clean fermentation that throws little to no diacetyl. Pitching rates and temperature can affect results with this strain (or any strain, for that matter). Treat this yeast well and the results will impress the lederhosen off you!
Beer Styles: Classic Rauchbier, Doppelbock, Eisbock, Maibock/Helles Bock, Munich Dunkel, Oktoberfest/Märzen, Schwarzbier (Black Beer), Traditional Bock.
Northwest Ale yeast hails from a brewery in Seattle, but has roots in the United Kingdom where it originated. It is known to be a very clean strain even at higher temperatures, with just enough fruit to give character without being overbearing. Light malt characters come out in the finish, which combines well with hops in the final product. This strain is often used in making IPAs and pale ales with an underlying malt complexity, but is a wonderful choice for many American style ales. Highly flocculant, this yeast clears well, yielding crystal clear beers.
Beer Styles: American Amber Ale, American Barleywine, American Brown Ale, American IPA & Pale, American Stout, Blonde Ale, American Pilsner, Fruit beer, Imperial IPA, Spice, Herb, or Vegetable beer.
Many brewers believe this to be the strain from Hoegaarden that gives Blue Moon its unique spice and tartness. Whether this rumor is true or not, this yeast is certainly our choice for classic witbiers, and makes excellent Belgian ales as well. It produces dominating phenolics, allowing spice notes, such as clove and peppercorn, to stand out over the more subtle esters this strain creates. It can be tart in the finish and ferment out somewhat dry. Because of this, it is well suited for use in beers with heavy amounts of wheat and oats, though you might try this with a rye beer as well. Belgian Witbier is a very vigorously fermenting yeast, and excess headspace of 33% is recommended in the primary fermenter, as well as a blowoff assembly. However, it has been known to be a strain that can take some time to fully attenuate, especially when fermenting cool. For making classic witbiers serves with a slice of citrus fruit, there is no substitute for this strain!
Beer Styles: Belgian Dubbel, Belgian Tripel, Spice, Herb, or Vegetable Beer, Witbier.
London Ale III is Wyeast's strain cultivated from the Boddington's brewery, long famous for their creamy pub ale. This yeast can be used to make similar ales, fruity and rich with a flavor profile allowing malt and hops to dominate in harmony. It can leave a slight sweetness and may not be quite as highly attenuative than other strain that leave beers drier. This makes London Ale III perfect for sweeter, more malt forward styles as well as rich, hoppy pales where malt sweetness is desired to balance out hop character. It is known to be a vigorous fermenter which leaves a thick krausen behind due to high flocculation. Cold-conditioning beers fermented with this strain will cause the highly flocculant yeast to drop out, leaving behind incredibly clear, delicious beers.
Beer Styles: American Amber Ale, English Barleywine, English IPA, Extra Special/Strong Bitter (English Pale Ale), Mild, Oatmeal Stout, Old Ale, Scottish Export 80/-, Scottish Heavy 70/-, Scottish Light 60/-, Southern English Brown, Special/Best/Premium Bitter, Standard/Ordinary Bitter, Sweet Stout.
Roselare is another great blend of yeasts and bacteria from Wyeast, designed to produce excellent sour beers, from fruit lambics and Gueuze to Flanders browns and red. The full gamut of yeast and bugs have been included in this blend: a Belgian ale strain, pediococcus, lactobacillus, flor sherry and two Brettanomyces strains. These all contribute their unique flavor and aroma to the beers in which they are utilized, creating uniqueness and depth of character. A sour pie cherry note is often associated with Roselare, and is very useful in the creation of representative Flanders beers. This blend does well if allowed to come into its own over a period of at least 18 months. Like the Belgian lambic blend by Wyeast, Roselare will change character over time if propagated due to genetic drift, and ferments beers extremely dry, especially with proper time and conditioning.
Beer Styles: Flanders Brown Ale/Oud Bruin, Fruit Lambic, Gueuze, Straight (Unblended) Lambic.
Wyeast's London Ale strain is a classic strain for fermenting all sorts of English and British ales, specifically milds, browns, porters, and stouts. Some fruitiness is to be expected, especially near the high end of the temperature range for this yeast (60-72°F). A minerally finish on the palate is expected. This strain is recommended on some high gravity styles as it can attenuate well, fully fermenting the beers in question.
Beer Styles: Brown Porter, Dry Stout, English Barleywine, Foreign Extra Stout, Mild, Northern English Brown Ale, Old Ale, Robust Porter, Russian Imperial Stout.
Thames Valley yeast is clean and relatively fruit-free, as opposed to some British strains that can be fruitier and more estery. Maltiness comes through in the finish, with some rich grain and honey notes. This yeast has been described as being somewhat minerally, and can lend complexity to beers without having an overly heavy flavor character. Hop character is allowed to come through, and many excellent English pale ales will benefit from this strain. It is also often used in the making porters and stouts, as the cleanliness of this yeast allows for cleaner flavor profiles in both of these styles. An excellent all-around English yeast for a wide array of beers.
Beer Styles: Brown Porter, Dry Stout, Düsseldorf Altbier, Extra Special/Strong Bitter (English Pale Ale), Foreign Extra Stout, Northern English Brown Ale, Robust Porter, Special/Best/Premium Bitter, Standard/Ordinary Bitter.
Originating from the August Schell brewery in Minnesota, Wyeast's American Lager strain has more complexity than the Pilsen Lager strain. The August Schell brewery is one of the oldest family-owned breweries in the United States, and as such, have developed unique house strains of yeast that produce beers with significant character. This strain is known to be more bold and robust than other strains used in the production of classic American Pilsners, but comes highly recommended by a number of brewers who have used it to great success.
Beer Styles: Classic American Pilsner, Dark American Lager, Lite American Lager, Premium American Lager, Standard American Lager.
Perhaps our most popular lager strain, California Lager yeast is a very versatile strain that makes wonderfully clean beers without cold fermentation temperatures. In fact, Wyeast states that this yeast is not recommended for cold fermentation. With a temperature range between 58°F and 68°F, beers made with this strain purportedly keep lagers characteristics up to 65°F, though beers fermented warmer than this may also be very lager-like as well. It is known as the quintessential yeast in the production of California Common beer, coming from the California brewery that may have saved the style from being lost to history. Malty and highly-flocculant, this strain behaves like a slightly-cool fermenting ale yeast while producing extremely clear lagers.
Beer Styles: Baltic Porter, California Common Beer, Christmas/Winter Specialty Spiced Beer, Cream Ale, Other Smoked Beer, Premium American Lager, Spice, Herb, or Vegetable Beer.
Belgian Ardennes might well be called the American Ale yeast of Belgian Strains. While Wyeast's American Ale yeast strain can be used in the production of almost any American ale, Ardennes can be used in the production of almost any Belgian ale, from light blondes and pales to dark and golden strong ales. It produces a subtle and well-balanced flavor profile, balancing the fruity esters typical of Belgian yeast with spicy and rich phenols. It is highly flocculant, therefore producing very clear beers with little effort. Try this in just about any Belgian style!
Beer Styles: Belgian Blond Ale, Belgian Dark Strong Ale, Belgian Dubbel, Belgian Golden Strong Ale, Belgian Pale Ale, Belgian Specialty Ale, Belgian Tripel, Flanders Brown Ale/Oud Bruin.
Wyeast's American Ale yeast is the definitive American ale strain. A clean, neutral profile with low ester production makes this the ideal choice for a wide range of beers, American or otherwise. This strain is used popularly in many breweries and homes alike as a house strain. While it is often used in American Pale Ales and IPAs, its versatility means it can produce many other styles with ease. Medium-to-low flocculation means that yeast will stay in suspension longer than more flocculant British strains, but will produce clean and crisp beers of exceptional quality.
Beer Styles: American Amber Ale, American Barleywine, American Brown Ale, American IPA, American Pale Ale, American Stout, Braggot, Brown Porter, Christmas/Winter Specialty Spiced Beer, Cream Ale, Dry Stout, Fruit Beer, Imperial IPA, Irish Red Ale, Other Smoked Beer, Russian Imperial Stout, Spice, Herb, or Vegetable Beer, Strong Scotch Ale, Wood-Aged Beer.
Wyeast's Belgian lambic blend is a very unique and complex blend of belgian ale yeast, lactobacillus, pediococcus, a sherry strain, and two brettanomyces strains. With all these different yeast and bacteria in one conveneint smack pack, brewers are sure to produce Belgian-style lambic beers and other traditional sours of unsurpassed quality. Because of genetic drift over time, it is not recommended to collect and reculture this blend if a consistent end product is desired. This blend is also known to be very highly attenuative, and beers often finish extremely dry, especially with extended conditioning times. A great choice in traditional Belgian style beers that are traditionally spontaneously fermented.
Beer Styles: Flanders Red Ale, Fruit Lambic, Gueuze, Straight (Unblended) Lambic.
Pediococcus, A.K.A. pedio, is a lactic acid producing bacteria, and as such is often used in a blend to create complexity and sourness in sour beers, lambics and gueuzes. Because it is known to produce diacetyl, many brewers and breweries pitch it together with a strain of Brettanomyces, which can clean up the diacetyl, as well as add more layers of complexity to a beer. Over time, acid production will increase in beers inoculated with pediococcus. Used when more acidity is desired, pediococcus can be utilized for just this purpose.
Beer Styles: Fruit Lambic, Gueuze, Straight (Unblended) Lambic.
Wyeast's German Ale strain has a wide temperature range and can ferment down to 55°F. Maltiness is accentuated, though some mild fruitiness can be expected at higher temperatures. Beers using this strain mature rapidly, even when fermenting cool. This German ale strain is less flocculant than many ale strains and may stay in suspension for longer than a British or American strain. A good choice for a wide range of German Ales.
Beer Styles: American Wheat or Rye Beer, Berliner Weiss, Bière de Garde, Düsseldorf Altbier, Kölsch, Northern German Altbier.
Belgian trappist high gravity yeast is an ideal yeast to use in the production of high gravity Belgian ales. It has good fruity esters reminiscent of dried stone fruits, which are balanced well with spicy phenolic compounds. Many fine dubbels and trippels have been made with this yeast. However, it can be used to wonderful effect in other Belgian styles, such as golden strong. It is a highly attenuative yeast, and can produce very dry beers that retain a lot of character and flavor when treated right. Many brewers, professional and homebrewers alike, find that this strain makes an excellent house strain for Belgian beers. Another top-cropping yeast strain, Belgian trappist high gravity can ferment vigorously, and extra care should be taken to avoid the inevitable messes that this eager strain can make. It can also produce a lot of sulfur during fermentation, but this clears up well, leaving behind wonderful beers full of delicious character.
Beer Styles: Belgian Dubbel, Belgian Golden Strong Ale, Belgian Specialty Ale, Belgian Tripel, Bière de Garde.
British Ale II lends a classic British character to beers. It combines high flocculation with a finish that can be, at times, slightly dry, though some have experienced this yeast to be a lower attenuating strain than some other British and American strains. It can be used to produce anything from cream ales to dry stouts, with every style in between. It is also used in a few more highly alcohol styles where malt notes form an invaluable backbone for other flavors.
Beer Styles: American Brown Ale, Brown Porter, Cream Ale, Dry Stout, English Barleywine, English IPA, Extra Special/Strong Bitter (English Pale Ale), Foreign Extra Stout, Irish Red Ale, Northern English Brown Ale, Special/Best/Premium Bitter, Standard/Ordinary Bitter
Czech Pils is a strain perfect for use in classic Bohemian and American pilsners, but does well in many dark, malty lager styles as well. This yeast allows malt to dominate in a dry finish that is crisp and satisfying. While the fermentation temperature range for this yeast stretches between 50°F and 58°F, sulfur production can be reduced by fermenting on the warm end, and Wyeast states that sulfur produced during fermentation will dissipate with conditioning. A unique yeast strain that will clear well and produce delicious beers with proper conditioning.
Beer Styles: Bohemian Pilsner, Classic American Pilsner, Dark American Lager, Munich Dunkel, Schwarzbier (Black Beer), Vienna Lager.
