As is common with liquids shipped in wooden barrels, leakage may be due to the fact that the barrel hoops have not been adjusted to take up the slack which can develop in storage, with the result that general slackness of hoops causes the staves to yield to normal pressure in stowage. It is possible that at the time of discharge the barrels may show no evidence of this pressure, but it may be found by careful examination that the staves were not being sufficiently gripped by the bands.
In the case of citrus syrup and other similar commodities, barn may be waxed internally, and therefore any slackness would not become apparent until they had been subjected to pressure in stowage, and for this reason slackness may escape notice at the time of shipment. See also FRUIT PULP.
