Barrels should be stored in a cool place and away from sunlight. This will protect both the exterior of
the barrel and the aging spirits inside. In time liquid will be absorbed by the barrel or evaporate,
generally about 5% over 2 years. Dry climates or heated homes tend to cause more evaporation.

You need to remember that wood is a material that needs to be hydrated, therefore, in the first few times you fill the barrel you will lose a percentage of the liquid and or liquor that is poured in, this will decrease with constant use. There are several factors that play a role in the percentage loss. Some of the factors can be the climate where you currently keep the barrel as well as the type of wood it is made of and its origin. Curing the barrel helps reduce any possible leaks it might have.

Any liquids poured inside the barrels should not stay more than three days as it can cause fungi and give off flavors that will affect the taste and quality of your beverage.

The best way to keep your barrel in good condition is to have it constantly filled with the beverage you would like to age. A second option would be to fill it with water but make sure to change it.

The barrel should not be empty for more than 6 days otherwise the hoops will begin to loosen and open cracks between the staves and the lids which will cause leaking.
