Oak barrels are ideal for storing a wide variety of alcoholic beverages, but these vessels have one feature. In order for them to retain the taste and aroma of wine or cognac, it is necessary to keep them constantly filled. But what to do in the off-season when the tank is empty and there is simply nothing to fill it with? If you are faced with a similar situation, we suggest using the tips below.
What to do with the barrel after use?
As soon as the drink stored in the tank comes to an end, it is advisable to immediately thoroughly wash the container with clean drinking water. After that, prepare a solution of soda ash (about 2 grams of this disinfectant per liter of boiling water) and scald the barrel thoroughly. Such an insignificant concentration of soda will not cause any harm, but it will remove all extraneous odors.
If immediately after this filling of the container is not provided, we perform the following actions:
- thoroughly wash the barrel again with clean cold water to remove even the smallest traces of the soda solution;
- we send the barrel for storage in any ventilated room – in a barn, utility room or summer kitchen.
In this case, it is advisable to place it on a specially prepared flooring made of boards in order to exclude the appearance of mold due to contact with damp earth.
Do not store the wooden barrel near a heating device, in direct sunlight, or near strong-smelling substances. Also, do not store the barrel filled with water.
Never wrap the tank in a plastic bag, as many internet sites advise. The thing is that when the temperature drops on the inner surface of such a “package”, condensation will surely appear, which will cause dampness, the appearance of mold and fungi. Follow our advice and the barrel will be in perfect condition for the new season.

Frequently Asked Questions
How do you prepare and cure a new oak barrel so it never leaks?
Insert the wooden spigot and fill the barrel completely with cold tap water for 48 to 96 hours before adding any spirit or wine. The dry Canadian white oak staves absorb water and expand against the steel hoops to form a permanent hydraulic seal.
How fast do small oak barrels age whiskey, bourbon, and moonshine?
Because a 2L to 5L oak barrel offers up to 8x more charred wood surface contact per liter than a commercial 200L barrel, spirits extract deep amber color, vanillins, and toasted caramel notes in 4 to 10 weeks.
How should an oak barrel be stored when empty?
Store barrels in a cool, shaded cellar (55%–70% relative humidity) away from radiators or direct sunlight. Keep spirit barrels filled with a small splash of high-proof neutral spirit or water changed weekly so the staves never dry out.
Canadian White Oak (Quercus alba) Stave Geometry & Long-Term Durability
A barrel’s longevity depends on quarter-sawn stave selection and mechanical hoop compression. At BarrelsWood in Ontario, our coopers split and air-season slow-growth Canadian white oak (Quercus alba) whose vessels are naturally plugged by dense microscopic tyloses. Joined purely by tongue-and-groove compression under heavy galvanized or stainless steel hoops—with zero synthetic glues, paraffin wax, or interior epoxy lacquers—each cask expands into a permanent hydraulic seal after a 48-to-96-hour cold water cure.
When maintained at 55–65°F (13–18°C) and 65%–75% cellar humidity between batches, a single 10L Oak Barrel ($210), 20L Oak Barrel ($215), or 50L Cellar Cask ($330) delivers 3 to 5 full spirit or wine maturation cycles across 8 to 15+ years of service.
