Description

What was a Seasonal Strain is now a permanent strain at MoreBeer due to a very positive overall response. This yeast can supposedly ferment up to 25% alcohol. We have not had the opportunity to test it anywhere near that type of alcohol. We welcome feedback from customers. Produces ester character that increases with increasing gravity. Malt character dominates at lower gravities. After using this yeast strain we found out that it can sometimes produce a Belgian Character and sometimes not. Try this yeast with your big Belgians as well as other unique hybrids and you will find yourself pleasantly surprised. We would not recommend it for creating classic true-to-style variations of Barleywines, Imperial Stouts, Strong Ales or any other high-gravity style where Belgian flavors would not be appropriate. This yeast might be a great fit for really big Dunkelweizens.

To find out how to ferment to 20-25% visit www.whitelabs.com

Also note that with any beer with a starting gravity over 1.060 you should consider using nutrients. A recommended nutrient schedule is to add Servomyces to the kettle at the end of the boil, and then follow that with a 6 grams per 5 gallons addition of Fermaid K half-way through the fermentation.

Attenuation: 80%
Flocculation: Medium
Fermentation Temperature: 65-69F

For best results we always recommend ordering an ice pack with your liquid yeast.

Powerful Beast Escaped from its Cage
This is one powerful beast. I've used it three times now, and each time I've gotten at least 85% attenuation within three days. It's led me to be super-careful about mash temperatures, because this monster will eat every last drop of fermentable sugar, leaving you with a bone-dry brew if you're not careful. It also has a wonderful flavor if you can get the temperature right: at < 70F, it imparts very little flavor; < 75F it can impart tart apple or pear flavors; > 75F it imparts vanilla/bubblegum flavors (delicious, IMO).

My advice: pitch this yeast into fresh wort, and run as fast as you can in the other direction before it gets you, too!

Powerful yeast
I designed a Belgian Tripel recipe that would ferment out to about 9.3% ABV. The Belgian yeast vial I had (WLP 530) was a few days past its prime but was plenty viable. I decided to add a half vial of WLP 099 to it just to be sure all the sugar fermented out.

The combination of the two yeasts exceeded my wildest expectations. They fermented well past my estimated final gravity and brought the beer to 11% ABV. The fermentation was amazingly vigorous (though I did use yeast nutrient and dissolved pure oxygen into it, so the yeast probably had optimal growing conditions).

The finished beer was delicious, with no off flavors, and packs quite a punch at that ABV level. I wouldn't hesitate to use that combination of yeasts again.

Must have for high gravity
Used with a Bourbon County RIS clone. Couldn't have achieved 12%ABV without it. Highly recommended.

Hit Our Target ABV
We were looking to get a higher ABV on our Belgian Strong. Achieved a little over our goal with 15.1%. Would love to try again to push the boundaries a little

great yeast
my go to yeast for anything 1.090 and up, works super fast, even eith poor aeration. one of a kind yeast that can handle any barley wine or super strong beer you may brew.

Worked great in a 20% abv barley wine
I used this yeast in a 3L starter to make a barley wine with multiple dextrose additions during fermentation in the spirit of Dogfishhead 120 min IPA. It kept chugging all the way to the end and approaching 20% ABV. I fermented between 64 and 68F and really enjoyed the fruitiness imparted by the yeast. The beer is still conditioning in secondary but I'm really happy with how this yeast handled the primary fermentation and will definitely use it again.

Really gets Stuff Going!
Great product started fermenting immediately!

Worked okay, need to try again.
I used this yeast to ferment one of my favorite Russain Imperial Stouts. Previously I was using 1056 on it with good results and attenuation. This time i got the gravity a little too high from boil off and this yeast failed to push it down to where I would like. I'll try it again with the proper gravity and see how it compares.

A Great Yeast !
Have been using for years with several beers and always great fermentations and excellent flavors from this yeast.

Imperial Stout
Pitched a 2L starter into an Imperial Stout @ 1.088 OG and it finished MONTHS ahead of my expectation. Didn't have a whole lot of the estery character I was thinking it would. I would use this again, but might pitch it into secondary after primary with a strain w/a more specific flavor profile.
