Description
A cold-running German strain for pilsner, American lager and vienna lager, with a short lag time even at the low end of its range. Esters are minimal and the finish is dry with a faint grainy note. Low flocculation leaves haze that needs a diacetyl rest and extended lagering to clear, and its 7 percent alcohol tolerance rules out strong or high-gravity worts.
