Ok, I was searching around for suggestions on yeast for an Oktoberfest (kit from NB). I've listened to the archives and done searches on the site and I've narrowed down to several choices. I prefer whitelabs over wyeast....just personal quirk.
Here is what I'm looking at...
WLP820, Oktoberfest/Marzen
WLP833, German Bock lager
WLP838, Southern German lager
So far I'm prepared to do a starter and can handle a long fermentation so time and equipment is not a problem. I just hear so many wonderful things about the 833 and 838, but how much of that "oktoberfest flavor" is derived from using a more "proper straing: 820?"
