barclay perkins for sure, or simply buying a large amount of some 2row barley malt, toasting some, making homemade crystal if you want etc. i think that would be the key thing in pre-industrial brewing. the physical act of dealing with the malt., potentially not using hops. i think do research on the evolution of beer and you can figure out something that interests you in creating.
anyone done any barclay perkins recipes to the letter?
