Comments: I brewed a barley wine with this yeast and had great results. It finished at 10%. My friend and family are begging me to brew it again.

Beers brewed: IPA, Amber, High Gravity Wheatwine
Brewery name: Sleeping Lady Brewing Co.
Comments: I purchased a 7bbl of WLP099 and propped it up in a 5 bbl batch of Amber with a gravity of 15P. The Amber turned out awful, it was overattenuated and astringent with some autolysis flavors. This was immediately following fermentation. The IPA was a little better because the hops masked the astringency a bit but it still was not as good as my house yeast. I would not recommend this yeast ! for average gravity beers. It is a great attenuator of high gravity worts but it tastes bad. I would recommend WLP001 instead as it attenuates well, flocs better than 099 and tastes much better. I will never buy this strain again.

(Editor's note: WLP099 is designed to be used in big beers that need a lot of attenuation, and the big flavors from those beers match well with the yeast. Others have used in normal gravity worts and enjoyed the results, however).

Q: Hello! I read with great interest your write-up on WLP099 yeast. I wonder if any of your customers have tried to make a 25% sugar wine using this yeast? I would love to see their results (and process) if it has been published.

A: People have, but we do not know of published recipes.

Q: I have some questions concerning your high gravity tips: Can a hand-held blender be used for both the initial and subsequent aerations?

A. This would not get good aeration; an aquarium pump with an inline air filter is better.

Q. In a 25L batch, what weight of yeast and nutrient should be used? Which nutrient(s)?

A. 1-3 vials of yeast would be good; 1 tablet of Servomyces.

Q. What would be the best temperature to control to, to minimize impurities? At this temperature how long would you estimate it would take for completion?

A. 75 degrees F would be good, which would take about 5-15 days to complete.
