Wine Production Volume

Flooring reflects reality: a batch that computes to 1,847.6 bottles physically fills 1,847 whole bottles, with the leftover 0.6 bottle's worth of wine either topped up into existing bottles or left as ullage — it can't become a sellable 1,848th bottle. Rounding up would overstate your actual inventory, which matters for label ordering, case-good purchasing, and revenue projections. The same logic applies to cases: 12-bottle cases are counted only when fully formed.

Those floors exist purely to prevent a zero, blank, or negative input from producing a nonsense result like an infinite or negative gallon figure — they don't reflect a realistic minimum harvest or press performance. In practice you should never see them applied unless you leave a field empty or enter an implausibly low value; entering your real tonnage and yield bypasses them entirely.

59.4 gallons is the exact volume of a 225-liter Bordeaux barrique, the barrel size that became the de facto commercial standard across most wine regions — 225 liters converts to 59.4 US gallons, not the other way around. The calculator divides total gallons by 59.4 to tell you how many of these standard barrels your press run would fill, which is the figure most wineries actually plan barrel purchases and cellar space around.

No — it only converts your entered tonnage and press yield straight through to gallons, liters, bottles, cases, and barrels, with no deduction for racking losses, fermentation lees, or evaporative loss during barrel aging (the "angel's share," typically a few percent per year). Your final bottled volume will come in below this calculator's figures once those real-world losses are factored in, so treat the output as a starting production estimate rather than a final bottling forecast.
