How much whiskey is in a barrel?
There are many variables in the yield of a barrel, but on average, our 15 gallon barrel option will yield 100-110 750 ml bottles at 80+ proof. There is a bit of loss through Angel’s Share (evaporation) and initial absorption, but these factors are fairly predictable. We barrel most whiskey at right around 120 proof (60% alcohol by volume) so when it’s cut to bottling strength the yield is higher with the added water. If you want to do the math, take 60% (120 proof) of 15 gallons for a total of 9 gallons of alcohol. Divide that by your final ABV precentage for total gallons.
