I managed to source a freshly dumped 10 gallon bourbon barrel and started the aging process for the first time. Should I expect the density of the syrup to change after ageing? I only ask because I'm spraying the barrel a lot to keep the staves tight, so I'm assuming the barrel may be absorbing some moisture (both inside and out?). Do those of you that age your syrup in bourbon barrels find the density gets a little heavier after ageing?
