Oh, you want an Oktoberfest that will be ready in 5 weeks do ya? IMPOSSIBLE!!!!!!!!!!!!!!!!!!!!
jk. I have this fermenting right now and all signs are pointing towards being 4 or 5 weeks until ready. Shout out to Brulosophy for all they do! I've done this once with the WLP029 Kolsch, was outstanding. This time around my LHBS was a bit limited on their yeast stash so I'm giving it a go with Wyeast's Bavarian lager strain and fermenting about 5 degrees cooler. Same idea though.
