Product details

A traditional Czech lager organic strain, Urkel allows for balance between hops and malt. It is the perfect choice for Bohemian-style Pilsners. This strain can be slightly sulphery during fermentation, but it cleans up during lagering. Fermentation at the higher temperature range will produce a beer with minimal sulfur and a light ester profile.

*NOTE:*During summer months, we include complimentary ice packs will all liquid yeast orders. However, it is difficult to guarantee that the ice packs will stay frozen given transit times and particularly hot temperatures. For this reason, we recommend ordering dry yeast during summer months.

Great fermentation at cold temperature

I made a starter 48 hours ahead of time due to pitching at 48F. I let the temp free rise to 51F and the first krausen foam appeared within 24 hours. At this temp, there has been plenty of sulphur, but I have no worries that it will dissipate during lagering. I usually use dry yeast, but for this Czech amber, I wanted to use an authentic Czech strain. Glad I did.

Dead on arrival

You sent me a package of years with an October 2019 manufacture date. By the time I received the yeast it was past it’s “ use within three months” date. It was dead and I was not pleased.

Love me some Imperial

Lagering like a champ at 47-51*F. Allowing time and true lager temperatures to clean and clear my German leichtbier. Excited to see how it turns out.
