Figuring out how much wine to buy for a wedding is one of those things that feels like it should be simple — and then suddenly you're deep in spreadsheets at 11pm wondering if 40 bottles is too many or not nearly enough. The good news: there's a straightforward formula, and once you know it, the math takes about two minutes.
This guide walks you through exactly how to calculate wine for your wedding reception, with ready-made tables for every common guest count, tips on the red vs. white split, and what to do about guests who don't drink.
The Simple Formula
Wine is typically the most popular drink at a wedding reception, accounting for roughly 40–50% of all drinks consumed when you're also serving beer and cocktails. If wine is your only alcohol offering, that number climbs to 70–80%.
A standard 750ml wine bottle pours approximately 5 glasses. The average wedding guest drinks about one glass of wine per hour. So the core formula is:
For a wine-only bar:
Bottles = (Guests × Hours × 0.75) ÷ 5
For a full bar (wine + beer + spirits):
Bottles = (Guests × Hours × 0.40) ÷ 5
Multiply by 0.75 instead of 1.0 to account for non-drinkers and guests who pace themselves.
For example: 100 guests, 5-hour reception, full bar. That's (100 × 5 × 0.40) ÷ 5 = 40 bottles of wine. Add 10–15% buffer and you're buying 44–46 bottles.
Wine Quantities by Guest Count
Here are pre-calculated amounts for common wedding sizes, assuming a 5-hour evening reception with a moderate drinking crowd and a full bar (wine, beer, and spirits).
| Guests | Total Bottles | Red Wine | White Wine | With 10% Buffer |
|---|---|---|---|---|
| 50 guests | 20 bottles | 9 bottles | 11 bottles | 22 bottles |
| 75 guests | 30 bottles | 13 bottles | 17 bottles | 33 bottles |
| 100 guests | 40 bottles | 18 bottles | 22 bottles | 44 bottles |
| 125 guests | 50 bottles | 22 bottles | 28 bottles | 55 bottles |
| 150 guests | 60 bottles | 27 bottles | 33 bottles | 66 bottles |
| 200 guests | 80 bottles | 36 bottles | 44 bottles | 88 bottles |
How to Split Red vs. White Wine
At most weddings, white wine outsells red by a meaningful margin — especially at evening summer receptions. A good default split is 45% red, 55% white. If your wedding is in cooler months, skew slightly more red (50/50). If it's outdoors in summer, go 40% red, 60% white.
A few other factors that shift the split:
Heavy meat-focused menu → more red. Light seafood or vegetarian menu → more white. Older crowd → slightly more red. Younger crowd → more white and rosé. Outdoor daytime wedding → more white and rosé by a wide margin.
Rosé is increasingly popular at weddings and worth adding as a third option — especially for summer weddings. If you include rosé, a reasonable split is 40% white, 35% red, 25% rosé.
What About Champagne for the Toast?
The champagne toast is calculated separately from your regular wine. Plan for one glass per guest regardless of whether they drink — the toast is a ritual, and even non-drinkers typically hold a glass.
| Guests | Champagne Bottles Needed | Note |
|---|---|---|
| 50 guests | 13 bottles | A standard bottle pours 4 glasses |
| 75 guests | 19 bottles | |
| 100 guests | 25 bottles | |
| 150 guests | 38 bottles | |
| 200 guests | 50 bottles |
Prosecco and Cava are excellent budget alternatives to Champagne for the toast — most guests can't tell the difference once it's poured in a flute, and you can save $8–15 per bottle.
Accounting for Non-Drinking Guests
The formula above already factors in a 25% reduction for non-drinkers and light drinkers. If you know your crowd skews heavily toward non-drinkers — say, a dry wedding or a family with many pregnant guests — reduce your totals by an additional 20–30%.
Don't forget to provide good non-alcoholic alternatives. Non-drinking guests who have interesting options (sparkling water, Spindrift, NA wines, batch mocktails) tend to be far happier than those handed a glass of tap water while everyone else has wine.
Where to Buy and What to Spend
For weddings, always buy from a retailer that accepts returns on unopened bottles — Total Wine, BevMo, and Costco all do. This lets you buy 15% more than you think you need without financial risk. Running out of wine at a wedding is a far worse outcome than returning two cases the next morning.
Budget roughly $12–18 per bottle for perfectly good wedding wine. You don't need to spend more — at a reception, presentation matters more than label. A well-chosen $14 bottle served at the right temperature in a clean glass beats a $30 bottle served lukewarm.
| Guests | Budget ($12/bottle) | Mid-range ($16/bottle) | Premium ($22/bottle) |
|---|---|---|---|
| 50 guests | ~$264 | ~$352 | ~$484 |
| 100 guests | ~$528 | ~$704 | ~$968 |
| 150 guests | ~$792 | ~$1,056 | ~$1,452 |
| 200 guests | ~$1,056 | ~$1,408 | ~$1,936 |
Quick Tips from Wedding Planners
Wine goes fast in the first hour. Guests arrive thirsty and nervous. Staff the bar heavily at the start and make sure wine is circulating during cocktail hour.
Temperature matters more than most couples realize. Red wine served too warm tastes flat. White wine served too cold loses its flavor. Red at 60–65°F, white at 48–55°F. Pull reds from the cooler 20 minutes before serving.
Rent glasses, don't buy disposable ones. Rental glasses are cheap ($0.50–1 each), return clean, and make the wine taste better. Plastic cups make even good wine taste cheap.
Order by the case for discounts. Most wine retailers offer 10–15% off when you buy by the case (12 bottles). Worth planning your order to hit case quantities.

How many bottles of wine for 50 guests?
For 50 guests at a 5-hour reception with a full bar, plan on 20–22 bottles of wine (9 red, 11–13 white). If wine is your only alcohol, increase that to 35–40 bottles.
How many bottles of wine for 100 guests?
For 100 guests at a 5-hour reception with a full bar, plan on 40–44 bottles of wine (18 red, 22–26 white). For a wine-only bar, budget 70–80 bottles.
How many bottles of wine for 150 guests?
For 150 guests at a 5-hour reception with a full bar, plan on 60–66 bottles of wine (27 red, 33–39 white). Always buy from a store with a return policy and add a 10% buffer.
Is it cheaper to buy wine by the case for a wedding?
Yes — most retailers offer 10–15% off when you buy 12 bottles of the same wine. Plan your order to hit case quantities where possible. For a 100-person wedding you're buying enough wine that a case discount saves $50–100 easily.
What wine should I serve at a wedding?
Crowd-pleasing choices: a smooth Cabernet Sauvignon or Malbec for red, a Sauvignon Blanc or unoaked Chardonnay for white. Avoid very tannic reds and heavily oaked whites — they're divisive. When in doubt, ask your wine retailer for their best-selling bottles in your price range; they answer this question constantly and know what works.
