When sipping from the Antiquities menu, hopefully you notice something unusual about the water.
For beers designated by the Antiquities logo, reverse osmosis is performed on Columbiana municipal water - stripping it of its chemical and mineral content and rendering it pure H2O. The pure H2O is then rebuilt to match each style's specific water source from its historic city of origin. Local water reports are obtained and replicated. For the Irish Red, you are drinking the same mineral content as a Dubliner. The English Pale is adjusted to match the sulfuric "snatchy" profile of Burton-Upon-Trent, England. Grains and hops are imported from their respective regions and yeast from their original breweries. For the helles (brewed with replicated Munich water), the grains and hops derive from Bavaria and the yeast grown from Spaten - where the Sedlmayrs invented the style in 1894. Antiquated (tedious and often entirely unnecessary by modern standards) practices like decoction mashes are deployed when historically appropriate, culminating in beers designed to deliver the most authentic representations possible.
The logo not only denotes these practices, but also a difference in corporate structure. Ownership shares of Antiquities differs from that of Ill Will Brewing and thus operates as a subsidiary.
Example Water Profile: Burton-Upon-Trent, England (in ppm)
Calcium 275, Magnesiun 40, Sodium 25, Sulfate 610, Chroride 35, BiCarbonate 270
The abnormally high concertration of sulfate, naturarlly occuring due to sandstone, lends a peculiar flavor (dubbed Burton Snatch) and sharpens bitterness giving rise to the styles of English Pale Ale, India Pale Ale, and Extra Special Bitter.
Ill Will Brewing also performs reverse osmosis, but instead builds brewing water with the specific intent to enhance certain characteristics of your beer. Antiquities plays by the rules, Ill Will ignores them.
