In this work, the effect of the barrel bung-hole stave on the volume loss during rum natural ageing in palletized (vertical) system is statistically assessed. Eighty-four traditional 250 L (+/- 10 L) hogshead barrels typically applied in rum natural ageing were studied. For the 50 % of the barrels the bung-hole stave was removed (without bung-hole: WBH) and the others barrels kept the bung -hole stave (BH). Barrels were jointly stored (randomly assorted) under palletized ageing system during one year into a non-conditioned cellar of the major rum producer in Cuba. The volume loss of the barrels was determined after one year of ageing period. Statistical analyses demonstrated significant differences in the volume loss between barrels with and without bung-hole staves. It was found, that the bung-hole stave can increase the average volume loss (%/year) in about 17% compared with barrels without bung-hole staves during rum ageing in palletized system at the studied conditions. Theoretical arguments to explain the increment of the liquid evaporation due to barrel bung-hole stave during palletized ageing system are presented and debated.
