This past spring, Barrell Craft Spirits introduced a new product to the market. That product was not just new to Barrell, it was new to the whiskey industry, at least commercially. It is the Barrell Infinite Barrel Project. Barrell took a number of different barrels (more on what these are in a moment) and blended them together. After some time marrying, Barrell then took a percentage of that blend and bottled it. It then replaced what it removed with additional barrels of whiskey. Rinse and repeat. Assuming Barrell does keep adding the same ratio of whiskey components as the first batch, the result is an ever changing whiskey experience.
