The Yeast Bay - Franconian Dark Lager (WLP4030)
Franconian Dark Lager is a single strain of Saccharomyces pastorianus that hails from the Franconia region of Germany. This yeast exhibits a short lag time and has flavour profile characteristics that complement dark, roasted malts. The dark malt complementing nature of this yeast makes it a perfect fit for any big, malt driven dark lagers. We recommend a brief diacetyl rest at ~ 60-65 ºF (2-3 days) at the end of primary fermentation. An extended lagering phase at 33-35 ºF will encourage the yeast to settle and create a clean profile.
