Wyeast 3763 Roselare Ale Blend

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 1318 London Ale III

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.


Wyeast 2124 Bohemian Lager

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.

Wyeast 3056 Bavarian Wheat Blend

Bavarian Wheat Blend from Wyeast is a perfectly balanced blend of a neutral ale strain and a fruity, spicy wheat strain. The two influence each other out nicely, the neutral ale yeast providing a balanced base while the wheat yeast produces esters and phenolics reminiscent of classic continental wheat beers. The resulting beers often have a fair fruit-and spice character without being too strong, making this yeast a great choice for making traditional German wheat beers that are subtle and balanced. A decently-flocculating strain that is not as overwhelming as other wheat strains, it is a good standby for those making a foray into German Wheat territory.

Beer Styles: Dunkelweizen, Weizen/Weissbier, Weizenbock.


Wyeast 4632 Dry Mead

This strain from Wyeast, is a great choice for dry meads, and is used in many award winning meads. Low foaming and with little or no sulfur production. Use additional nutrients to aide in the fermentation process for mead making.

Ideal Temp Range: 55-75F (13-24C) | Alcohol Tolerance: 18% | Flocculation: Low-Medium


Wyeast 1332 Northwest Ale

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.


Wyeast 3944 Belgian Witbier

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.


Wyeast 1084 Irish Ale

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.

Beer Styles:   American Barleywine, Baltic Porter, Dry Stout, Foreign Extra Stout, Imperial IPA, Irish Red Ale, Oatmeal Stout, Other Smoked Beer, Robust Porter, Scottish Export/80, Scottish Heavy/70, Scottish Light/60, Spice, Herb, or Vegetable Beer, Strong Scotch Ale, Sweet Stout, Wood-Aged 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.

Ideal Temp Range: 65-75F (18-24C) | Alcohol Tolerance: 11% | Flocculation: Medium


Wyeast 5733 Pediococcus

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 5526 Brett Lambicus

Brettanomyces Lambicus, like many of Wyeast's wild yeast strains, comes from a Belgian brewery. Its dominant aromatic component is a very distinctive sour pie cherry, which comes through in the nose and on the palate, together with traditional leathery Brett notes. The character that this strain of Brett produces are highly sought after and go well in many different sour beers, especially fruit lambics. It works best in conjunction with other yeasts and bacteria in a blend, creating an unparalleled Belgian sour profile. Wyeast recommends conditioning with Brett Lambicus for 3 to 6 months to fully develop its unique flavor and aroma properties.

Beer Styles: Berliner Weisse, Flanders Red Ale, Fruit Lambic, Gueuze, Straight (Unblended) Lambic.


Wyeast 3638 Bavarian Wheat

Bavarian Wheat from Wyeast is another great strain to use in the production of German wheat beers, as well as roggenbiers. It is popularly known to have a more complex ester profile than other strains such as Weihenstephan. Notes of apple, pear, and other fruits complement the banana esters typical of German wheat strains. This strain also has a subtle vanilla undertone intertwined in its spicy clove phenols. As with other strains, Bavarian wheat can be manipulated to produce more fruity esters at warmer temperatures and more phenolic compounds lower, and high pitching rates can diminish or eliminate the estery flavors and aromas. It is also known to be a very vigorous fermenter and a low flocculator that stays in suspension for an extended period. Be conscious of its powerful fermentation activity and plan accordingly, with extra headspace in the primary fermentor and a blowoff tube. Also, be aware of the flavorfully complex wheat beers that this yeast can produce!

Beer Styles: Dunkelweizen, German Hefe-Weizen, Roggenbier (German Rye Beer), Weizen/Weissbier, Weizenbock


Wyeast 3787 Belgian Trappist High Gravity

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.

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.
