Here is an extremely rare American whiskey: one of the only bottled-in-bond single malts. It is extremely difficult to do. Bottled-in-Bond has a higher production standard than single-malt Scotch and more protective rules than Cognac. It must come from a single US distillery and be the product of a single distilling season. Bottled-in-bonds whiskies must also be aged for at least 4 years in oak barrels, in a federally bonded warehouse, bottled at 100 proof and contain no additives whatsoever. This Single-Malt is made of 100% non-GMO malted barley grown in California, Washington and Ireland. Wright & Brown mill, mash, ferment, distill, barrel-age and bottle it on site in Oakland, just across the Bay, east of San Francisco.
