20 Litre American Oak Aging Barrel

You know your recipe. Now build inventory.

The 20 Litre American Oak Aging Barrel is for the home enthusiast or bar program that has moved beyond experimentation and knows what the finished batch should taste like. Handcrafted from American white oak with a medium char, it gives you the capacity to turn a proven method into a meaningful run of finished bottles.

20L — The Inventory Barrel

The 20L is not simply a restaurant or commercial barrel. It is the natural next step for anyone who has perfected a whiskey finish, spirit blend or barrel-aged cocktail and wants enough finished volume to create a real bottled inventory.

Age your proven batch, then bottle it, label it, date it and wax it. Build a private bottle library for your home bar, create your own numbered releases, prepare bottles for special occasions, or maintain a repeatable signature batch for a hospitality program.

A 20L fill represents about 26 standard 750 mL bottles before tasting and normal barrel loss. In practice, a finished batch can produce roughly 25 bottles, depending on sampling and evaporation.

Build a Bottle Library

At this stage, the barrel is part of a complete process: develop the recipe in a smaller barrel, prove that you can repeat it, scale the batch, track the aging window, bottle the finished liquid and organize the inventory. That gives every bottle a story and every new batch a reference point.

See how the same barrel-to-bottle approach can be used in a real bar program, including aging, bottling, labeling, dating and wax finishing.
