Yes! It's Actually 3.94 Gallons...
And now you all know how bad I am with math!
Good job to all who caught the discrepancy and came up with the actual answer which is approximately 3.94 gallons after aging for 25 years in barrels. I hope this exercise helped to underscore the reality surrounding the process of aging balsamic in barrels in Modena for 25 years, let alone 50+ - and exactly how ridiculous it is to say that one has copious amounts of this staggeringly rare product for dispensing out of bulk containers - despite how thick it may look coming out of the spigot.
