General Info
This is my first ever true lager, made possible by the purchase of a 7 cubic foot chest freezer hooked up to a Johnson Controls temperature regulator. I will use this setup for both fermentation and lagering.
Due to worldwide hops shortage, I had to use Magnum and Tetnanger hops insead of Hallertauer as planned. Brew store only had half of German Pils needed, substitued some Belgian Pils for the other half.
