Great for Porters and Stouts

This is a fantastic yeast for porters and stouts. I have used it for a coffee stout and a bourbon barrel porter with great success. I made a 1.5L starter to give this yeast a high cell count for the 1.65 gravity porter,

The strain is fairly aggressive and will floc well after fermentation, but I would recommend a blow-off tube for other than a lower gravity recipe.

This yeast produced very few off-flavors as compared to other yeasts I have tried for stouts and porters. I have to believe that using better crystal malts and well-oxygenating the wort have something to do with the smoother flavor as well.
