I used the new WLP862 Cry Havoc yeast strain for the first time this week. I pitched it into 5 gallons of 1.062 wort at 75°F.
I used the new WLP862 Cry Havoc yeast strain for the first time this week. I pitched it into 5 gallons of 1.062 wort at 75°F. It took almost 40 hours to start fermenting. Did I under-pitch originally?

Lag times certainly vary, but the Cry Havoc can be a slow starter (based on our trials). You did not under-pitch as it was starting to ferment.

WLP833 German Bock Lager Yeast

From the Alps of southern Bavaria, this yeast produces a beer that is well balanced between malt and hop character. The excellent malt profile makes it well suited for Bocks, Doppelbocks, and Oktoberfest style beers. Very versatile lager yeast, it is so well balanced that it has gained tremendous popularity for use in Classic American style Pilsners. Also good for Helles style lager beer.
