Im working on a paper and want to know what everyone thinks are some of the most hotly debated brewing techniques?
Two that immediately come to mind are:
Extract vs. All Grain
SS vs plastic vs glass for fermentation. A boring debate based on opinions alone.
dry v. liquid yeast...
Fly vs batch sparging
Stainless steel vs aluminum brew-pots.
How about the plastic mash tun debacle we had recently?
