Description
A Kölsch-type Saccharomyces cerevisiae that stays out of the way of the hops, adding only faint citrus and floral esters. Cold fermentation keeps it neutral and crisp; run it warmer and it turns noticeably more fruit-forward. It can be slow to start but then holds a steady pace and drops reasonably bright.
