Damn good yeast
Used a double does in a 1.100 barley wine fermented above 75 degrees. Fermented well off the bat and stayed good in the bottle for years afterward. A little hard to tell what yeast characteristics it provided with all the other stuff flying around, but it had good flocculation with specified attenuation.

Great Flavor
Living in Texas where its stays warm 9 months out of the year, this yeast allows me me to ferment without the off flavors. When it does cool down (around 55-60 F) this yeast really does a great job on the flavor and taste to a South Texas ale.

Great Summer Yeast
Used this yeast mostly because it can ferment in warmer weather (being able to use in 75 degrees is a must in Kentucky). Was able to keep it around 70 degrees in the basement, it was a little slow starting off but shot off around the 24hr mark filling the basement with great fruit aromas which also come through nicely in the taste. Overall this is a killer yeast for summer brewing being able to ferment at higher temperatures and also adds a great aroma and taste to the beer. A must try!

Excellent flavor
I was a little concerned at first - this was my slowest starting yeast. I thought I'd ruined a batch. Confession - I'm an impatient brewer. I was really excited when it finally started. Primary and secondary fermentation were much slower than I'm used to, but I hung in there, and am very pleased with the flavor and clarity of my brew (British bitter with honey).

So much flavor.
Wow, this yeast give so much flavor to the lightest, simplest beers. I recently used 1099 in an Irish golden ale recipe (60% optic, 30 white wheat, 10% mild malt, Kent Goldings to bitter and Cascade for aroma). A very simple beer that turned out wonderfully. In the nose and taste I pick up peach and pineapple from the malt and that classic grapefruit flavor from the Cascade hops. The fruit flavors did not overpower the hops. This yeast is well balanced and I fermented at around 74 degrees.The color (6 srm) turned out to be bright gold and it was crystal clear. You need at least 7-10 days in the bottle to get your carbonation right because this yeast drops out so quickly. I did give the bucket a few swirls near the end of fermentation and it chugged along slowly the last couple of days.So gonna get more of this.
