This question might be a bit broad, but what I'm trying to understand is generally how the brewing process and the subsequent end result differed before the early-modern to modern era.
I had asked a question here some months back on where I could find some historical styles of beer, but without having much luck I thought I'd try to get at least an understanding of what's known about the evolution of beer from ancient to medieval to modern times.
So the question is: if I was a European medieval man drinking beer circa 6th-15th centuries what would that beer have been like? How did it differ from what we've been brewing for the last few centuries? And is that product distinct from what existed in ancient times?
