SPECIALTY/BELGIAN YEAST

WLP300 Hefeweizen Ale Yeast
This famous German yeast is a strain used in the production of traditional, authentic wheat beers. It produces the banana and clove nose traditionally associated with German wheat beers and leaves the desired cloudy look of traditional German wheat beers.
Attenuation: 72-76%
Flocculation: Low
Optimum Fermentation Temperature: 68-72°F
Alcohol Tolerance: Medium

WLP320 American Hefeweizen Ale Yeast
This yeast is used to produce the Oregon style American Hefeweizen. Unlike WLP300, this yeast produces a very slight amount of the banana and clove notes. It produces some sulfur, but is otherwise a clean fermenting yeast, which does not flocculate well, producing a cloudy beer.
Attenuation: 70-75%
Flocculation: Low
Optimum Fermentation Temperature: 65-69°F
Alcohol Tolerance: Medium

WLP351 Bavarian Weizen Yeast
Former Yeast Lab W51 yeast strain, acquired from Dan McConnell. The description originally used by Yeast Lab still fits: "This strain produces a classic German-style wheat beer, with moderately high, spicy, phenolic overtones reminiscent of cloves." 
Attenuation: 73-77%
Flocculation: Low
Optimum Fermentation Temperature: 66-70°F
Alcohol Tolerance: Medium

WLP380 Hefeweizen IV Ale Yeast 
Large clove and phenolic aroma and flavor, with minimal banana. Refreshing citrus and apricot notes. Crisp, drinkable hefeweizen. Less flocculent than WLP300, and sulfur production is higher. 
Attenuation: 73-80%
Flocculation: Low
Optimum Fermentation Temperature: 66-70°F
Alcohol Tolerance: Medium

WLP400 Belgian Wit Ale Yeast
Slightly phenolic and tart, this is the original yeast used to produce Wit in Belgium.
Attenuation: 74-78%
Flocculation: Low to Medium
Optimum Fermentation Temperature: 67-74°F
Alcohol Tolerance: Medium

WLP410 Belgian Wit II Ale Yeast:
Less phenolic than WLP400, and more spicy. Will leave a bit more sweetness, and flocculation is higher than WLP400. Use to produce Belgian Wit, spiced Ales, wheat Ales, and specialty Beers. 
Attenuation: 70-75%
Flocculation: Low to Medium
Optimum Fermentation Temperature: 67-74°F
Alcohol Tolerance: Medium

WLP500 Trappist Ale Yeast
From one of the few remaining Trappist breweries remaining in the world, this yeast produces the distinctive fruitiness and plum characteristics. Excellent yeast for high gravity beers, Belgian ales, dubbels and trippels. 
Attenuation: 75-80%
Flocculation: Medium to low
Optimum Fermentation Temperature: 65-72°F
Lower temperatures (under 65) will result in less fruity and more earthy beers.
Alcohol Tolerance: High

WLP510 Bastogne Belgian Ale Yeast:
A high gravity, Trappist style ale yeast. Produces dry beer with slight acidic finish. More ‘clean’ fermentation character than WLP500 or WLP530. Not as spicy as WLP530 or WLP550. Excellent yeast for high gravity beers, Belgian ales, dubbels and trippels.
Attenuation: 74-80%
Flocculation: Medium 
Optimum Fermentation Temperature: 66-72°F
Alcohol Tolerance: High

WLP515 Antwerp Ale Yeast
Clean, almost lager like Belgian type ale yeast. Good for Belgian type pales ales and amber ales, or with blends to combine with other Belgian type yeast strains. Biscuity, ale like aroma present. Hop flavors and bitterness are accentuated. Slight sulfur will be produced during fermentation, which can give the yeast a lager like flavor profile.
Attenuation: 73-80%
Flocculation: Medium
Optimum Fermentation Temperature: 67-70°F

WLP530 Abbey Ale Yeast:
Used to produce Trappist style beers. Similar to WLP500, but is less fruity and more alcohol tolerant (up to 15% ABV). Excellent yeast for high gravity beers, Belgian ales, dubbels and trippels.
Attenuation: 75-80%
Flocculation: Medium to high
Optimum Fermentation Temperature: 66-72°F
Alcohol Tolerance: High

WLP550 Belgian Ale Yeast
Saisons, Belgian Ales, Belgian Reds, Belgian Browns, and White beers are just a few of the classic Belgian beer styles that can be created with this yeast strain. Phenolic and spicy flavors dominate the profile, with less fruitiness then WLP500.

Flocculation: Medium
Optimum Fermentation Temperature: 68-78°F
Alcohol Tolerance: Medium-High

WLP565 Belgian Saison I Yeast
Classic Saison yeast from Wallonia. It produces earthy, peppery, and spicy notes. Slightly sweet. With high gravity saisons, brewers may wish to dry the beer with an alternate yeast added after 75% fermentation. 
Attenuation: 65-75%
Flocculation: Medium
Optimum Fermentation Temperature: 68-75°F
Alcohol Tolerance: Medium

WLP566 Belgian Saison II Yeast
Saison strain with more fruity ester production than with WLP565. Moderately phenolic, with a clove-like characteristic in finished beer flavor and aroma.  Ferments faster than WLP565.
Attenuation: 78-85%
Flocculation: Medium

Flocculation: Low
Optimum Fermentation Temperature: 68-75°F
