From BYO Magazine jan feb 2019 p. 54. Notes on Imperial yeast. LHBS says the lager yeast is great for this style beer. Lagering unnecessary. Just reduce temps as long as possible He fermented in basement and produced great beer. I will be using a fermentation chamber converted fridge. Will see how it goes.
