These barrels have a capacity of over 75 litres, (just over 16 imperial gallons). Finishes and colours may vary slightly as these are produced from natural materials and as a result of this, size variation of approximately 15% can occur. They feature a variety of finishing touches, all are based around a core design that include standard, hand curved staves and metal bands, but finishing specifications do differ and some may be daubed with paint around the bilge.
Note that whisky barrels are made to hold moisture; whilst empty, especially in drier weather, the wood may temporarily shrink. As such, some bands may become loose. Once the barrel has been filled with soil, the timber will expand and the bands will remain tight again. If the bands are loose they only require being tapped back into place.
