The new George Dickel Single Barrel Aged At Least 15 Years, according to those behind it, is an older Tennessee whiskey that’s being made available to purchase by the bottle from retailers or by the barrel directly from the distillery. Those who order a barrel, noted the brand, “are able to add custom branding and messaging to their bottles and choose from the highest proof options that were stored in the top tiers of the warehouse. Those buying-by- the—bottle can expect to see a variety of proofs of the liquid at their retailers.”
