Mulled wine calculator
Guests, ounces each and bottle price — the bottle count follows from them, rounded up.
★ FOOD · HOLIDAY · MULLED WINE
On the default figures — 12 guests, 5 ounces each, $9.00 a bottle — the answer is 60 ounces, 3 bottles, $27.00 in all. Change any figure and the ounces, bottles and total update at once, so a bigger party never catches the mulled wine short.
Guests, ounces each and bottle price — the bottle count follows from them, rounded up.
The bottle count is the number of bottles to buy, not the number of glasses poured: 60 ounces from bottles of 25.4 ounces is 3 bottles, and a party needing 61 ounces is still 3 bottles, because the third bottle holds 76.2 ounces and only the sixty-first ounce past two full bottles opens it. The total cost follows the bottles, not the ounces, so a bottle that is only half poured still costs a full bottle price — which is why bottle size matters as much as guest count when the budget is tight, and why a 750 ml bottle is the figure to check against your own shelf, not a litre bottle.
| Output | Formula | What it means |
|---|---|---|
| Total ounces | Guests × ounces per guest | Ounces the party must pour, before bottles are counted. |
| Bottles | Total ounces ÷ 25.4, rounded up | Bottles to buy; a part bottle counts as a whole bottle. |
| Total cost | Bottles × price per bottle | What the bottles cost in all, at the price you entered. |
First, check the ounces per guest against the party: a small festive glass is 5 ounces, while a generous mug is closer to 8, and that difference across twelve guests is a whole bottle. Second, check the bottle size against your own shelf: 25.4 ounces is a standard 750 ml bottle, while a litre bottle holds 33.8 ounces and changes the count. Third, check the price per bottle against the basket: $9.00 a bottle should look like the wine alone, since oranges, spices and sugar sit on top of it.
Twelve guests are coming, each drinking 5 ounces, and a bottle holds 25.4 ounces at $9.00 a bottle. Ounces are 12 × 5 = 60. Bottles are 60 ÷ 25.4 = 2.36, rounded up to 3. Cost is 3 × $9.00 = $27.00. If four more guests arrive, the same steps give 16 × 5 = 80 ounces, 80 ÷ 25.4 = 3.15 bottles rounded up to 4, $36.00 at $9.00 a bottle — and if the glass were a generous 8 ounces, the original 12 guests would need 96 ounces, 4 bottles instead of 3, which is exactly the kind of check that saves a dry pot.
At 16 guests the answer moves to 80 ounces, 4 bottles, $32.00 at $8.00 a bottle, because the eighty-first ounce past three bottles opens a fourth. At 6 ounces each the answer rises to 72 ounces, 3 bottles, $27.00 at the default price, since three bottles hold 76.2 ounces. At $0.00 a bottle the bottles stay 3 and only the total drops to $0.00, which is the cellar-stores case: the bottles are still needed, only the new spending disappears.
The calculator is exact for the figures you enter, but the figures themselves are judgements: ounces per guest varies with the glass, and a bottle varies a little by brand. A mug poured generously holds more than a small glass, so pour one glass once, measure the ounces, and use that number. The rounding is always up, which is the safe direction for a party: an extra bottle is next weekend’s wine, a missing bottle is a dry pot.

On the default figures, 3 bottles: 12 guests at 5 ounces each need 60 ounces, and bottles of 25.4 ounces hold 76.2 ounces across 3 bottles.
Five ounces is the default here, about a small festive glass — a generous mug is closer to 8 ounces.
A standard 750 ml bottle holds 25.4 ounces; a litre bottle holds 33.8 ounces and changes the bottle count.
Then the party needs 80 ounces at 5 ounces each — 4 bottles, $32.00 at $8.00 a bottle.
Because wine from the cellar costs nothing new: the bottles stay 3, only the new spending drops to zero.
Yes — one spare bottle across 12 guests is cheap insurance against a pot that empties before the last toast.
