Some friends and I are going all-in together with a 50 gal batch of Altbier this weekend. In collecting the ingredients I messed up and got 1 bag of Weyerman Type 2 (dark) instead of Type 1 (light). For this batch, we'll be using the following recipe (based on Kai's, but with some melanoidin subbed in since we can't decoct this enormous volume):
Munich I - 80 lbs - 82%
CaraMunich I - 10 lbs - 11%
Carafa II Special - 1 lbs - 1%
Melanoidin - 6 lbs - 6%
I have 50lbs of Munich I (light) on hand so I'm just short 30 lbs. Can I just use the darker Munich in place of that, and just end up with a little darker beer? Or should I split that 30lbs between Vienna and the dark Munich? Or split it Pils and the dark Munich? (I have enough Pils and Vienna on hand) We're not planning to enter this in a comp, and we don't care if we're a little darker than style, but we also don't want it coming out too malty or full like a Dunkel (I love Kai's dunkel recipe, which is 99% dark Munich and 1% Carafa II).
Any tips?
