JY001 - Czech Lager I
JY001 is a beautiful strain from a small Czech microbrewery isolated by Jasper Yeast. A very smooth flavor with a touch of maltiness, this yeast will bring out the best in your refreshing lager! Aromatics produced complement hoppy pilsners perfectly while also letting the malt shine. A slow starting strain but one that keeps on chugging until the job is done. Can be used at higher temperatures without problems, lagering cold when fermentation is complete for a minimum of 3 weeks is advised. Flocculates very hard, resulting in a dense yeast cake - plan ahead when you intend to repitch.
