How Much Alcohol for a Wedding? Calculator & Guide
"How much alcohol do we need for the wedding?" It's one of the first questions you'll ask once the venue is booked and the guest list is drafted. Too little, and the party might fizzle out early. Too much, and you're left with cases of vodka and a bill that was higher than it needed to be. In this guide, you'll find specific per-person amounts, ready-to-use calculations for 50, 100, and 150 guests, and the key factors that can change your numbers. All presented responsibly—with an emphasis on moderation and a safe celebration. If you just want a quick answer without the maths, use our wedding alcohol calculator. Here, we'll break down the logic behind it.
The Per-Person Calculation for Adult Guests
The foundation of any good estimate is the amount per person. The figures below are tried-and-tested planning ranges for one adult guest who drinks alcohol at a lively wedding reception that lasts until the early hours. Use the lower end of the range if your guests are a quieter crowd or if many don't drink; aim for the higher end if you're expecting a big party.
| Drink | Amount per person | Planning estimate |
|---|---|---|
| Vodka | 0.3–0.5 L | 0.4 L |
| Wine (table) | 0.3–0.5 L | 0.4 L |
| Beer | 1–2 bottles (0.5–1 L) | 1.5 bottles |
| Champagne / Prosecco (for the toast) | 0.1–0.15 L | 0.1 L |
| Soft drinks | 1.5–2.5 L | 2 L |
| Water | 1–1.5 L | 1.2 L |
Two important notes. First: these numbers are calculated based on adult guests who drink alcohol, not your entire guest list. If you have 100 guests, including 10 children and 10 non-drinkers, you should calculate the alcohol for 80 people, but the soft drinks and water for all 100. Second: you don't need to offer every single category. Most couples opt for a core selection of vodka + wine + beer, with champagne just for the toast, and allocate the rest of the budget to soft drinks and water.
How Much Alcohol for a Wedding — Ready Calculations for 50, 100, and 150 Guests
The table below translates the planning estimates into a real shopping list. The assumption is that roughly 80% of your guests are adults who drink alcohol (i.e., 40, 80, and 120 people, respectively), while soft drinks and water are calculated for everyone present.
| Drink | 50 guests | 100 guests | 150 guests |
|---|---|---|---|
| Vodka (0.4 L/person) | ~16 L → 32 x 0.5 L bottles | ~32 L → 64 x 0.5 L bottles | ~48 L → 96 x 0.5 L bottles |
| Wine (0.4 L/person) | ~16 L → 22 x 0.75 L bottles | ~32 L → 43 x 0.75 L bottles | ~48 L → 64 x 0.75 L bottles |
| Beer (1.5 bottles/person) | ~60 x 0.5 L bottles | ~120 x 0.5 L bottles | ~180 x 0.5 L bottles |
| Champagne for toast (1 btl. ≈ 7 ppl) | ~7 x 0.75 L bottles | ~12 x 0.75 L bottles | ~18 x 0.75 L bottles |
| Soft drinks (2 L/person) | ~100 L | ~200 L | ~300 L |
| Water (1.2 L/person) | ~60 L | ~120 L | ~180 L |
A practical example for 100 guests: you'd buy around 64 half-litre bottles of vodka, 40–45 bottles of wine, 5 cases of beer (24 bottles each), a dozen or so bottles of bubbly for a single toast, and a generous supply of water and soft drinks. This is a "well-stocked for a big party" scenario—for a more relaxed crowd, you could easily reduce the alcohol quantities by 15–20%.
A rule for a safe party: it's always better to plan for slightly less hard liquor and significantly more water and soft drinks. Having plenty of water available on tables and at the bar is the cheapest way to ensure your guests have a great—and safe—time all night long.
How Much Vodka for a Wedding
In many cultures, vodka is a wedding staple, but it's also the easiest to over-buy. A safe starting point is 0.3–0.5 L per adult guest who enjoys spirits. In practice:
- 0.3 L/person — A good amount when you have a mixed-age crowd, lots of guests who prefer wine or beer, or a reception that ends before midnight.
- 0.4 L/person — The universal middle ground and a great place to start your calculations.
- 0.5 L/person — Only for a really lively crowd that you know prefers vodka over wine and beer.
Vodka is usually placed on tables in 0.5 L bottles (one per 2–4 guests) or served from the bar. If you're buying it yourself, ask your venue about their corkage fee, as this can sometimes be added to your bill.
How Much Wine and Champagne for a Wedding
Wine is perfect with meals and for guests who don't drink spirits. You'll get about 6 glasses from a standard 0.75 L bottle. Plan for 0.3–0.5 L per wine-drinking guest—which works out to roughly one bottle for every 2 people over the course of the evening. It's a good idea to split your purchase between white and red, aiming for a 50/50 ratio, or slightly favouring whichever best complements your menu.
Champagne or prosecco is, in most cases, only needed for a single toast—either a welcome toast or one at midnight. The calculation here is simple: a 0.75 L bottle fills 6–8 flutes, so one bottle will serve 6–7 guests. For 100 people, that means buying around 12–15 bottles. If you plan to have bubbly available for guests to help themselves to all evening, the quantity needed will increase several times over—in which case, a good sparkling wine is often a more budget-friendly choice.
| Occasion | How much champagne | Example (100 guests) |
|---|---|---|
| One toast | 0.1 L/person (1 btl. ≈ 7 ppl) | ~12–15 bottles |
| Welcome toast + midnight toast | 0.15–0.2 L/person | ~20–27 bottles |
| Champagne available all evening | 0.4 L+/person | 50+ bottles |
How Much Beer for a Wedding
Beer is often underestimated in wedding planning, but it can disappear faster than vodka—especially in summer and with a younger crowd. Assume 1–2 bottles (0.5 L) per person, with 1.5 bottles as a good starting point. For 100 guests, that's about 120 bottles, or 5 cases of 24. If you're opting for draught beer, convert this to litres (1.5 × 0.5 L = 0.75 L per person) and confirm the keg size with your venue.
How Many Soft Drinks and How Much Water
This is the one category where you must not cut corners—and it's one of the most common mistakes couples make when they only focus on alcohol. Guests will drink soft drinks and water all evening, whether they're drinking alcohol or not.
- Soft drinks (cola, juices, lemonade, tonic, flavoured water): 1.5–2.5 L per person — plan for 2 L.
- Water (sparkling and still): 1–1.5 L per person — and make sure it's readily available on tables and at the bar.
- Remember your drivers, pregnant guests, children, and non-drinkers—for them, an attractive selection of non-alcoholic options is just as important as the vodka is to everyone else.
For 150 guests, this adds up to around 300 L of soft drinks and 180 L of water. A plentiful supply of water isn't just good hospitality—it's a key ingredient for a safe and long-lasting party.
What About Cocktails and Liqueurs?
If you're planning a cocktail bar, you'll need to factor in base spirits (gin, rum, whisky, liqueurs) and mixers (tonics, juices, fruit, ice). It's hard to give a single calculation here—the amount you need depends on your cocktail menu and whether the bar is open all night or for specific hours. A practical approach:
- Limit the menu to 3–5 signature cocktails to control your shopping list and keep service moving.
- Assume that some of the vodka/wine consumption will shift to cocktails, and reduce your base quantities of those drinks accordingly.
- Homemade liqueurs can be a charming, personal touch, but they are strong. Treat them as a small tasting extra (served in small glasses), not as a primary alcoholic drink.
A bar with ice, fruit, and a few great non-alcoholic options (mocktails) often makes a bigger impression than another case of vodka—and encourages moderation.
Factors That Change the Numbers
These calculations are a starting point. Before you finalise your order, adjust the numbers based on the specifics of your wedding:
- The season. In summer, consumption of beer, water, and soft drinks goes up; in winter, guests tend to drink more wine and spirits. In hot weather, increase your water and soft drinks budget by 30–40%.
- Your guest profile. A younger crowd with lots of friends who love to dance will likely mean more alcohol. A guest list with lots of family, children, and older relatives means less hard liquor and more wine and soft drinks.
- Length of the reception. A party that goes on until the early hours will use significantly more than one that wraps up at 2 a.m.
- Open bar vs. table service. With an open bar, consumption can be higher than when bottles are just on the tables—it's easier for guests to get a top-up.
- The food menu. Hearty, hot meals served regularly will slow down alcohol consumption. Serving alcohol without enough food is never a good idea.
- Number of children and non-drinkers. Every one of these guests means less alcohol but more soft drinks and water.
How to Avoid Overpaying and Ending Up with Leftovers
A smart calculation isn't just about "how much to buy," but "how to buy wisely."
- First, count the drinking adults, not the entire guest list. This is the first step to cutting your costs by a significant percentage.
- Buy from a supplier with a sale-or-return policy. Many wholesalers and retailers will take back unopened, undamaged cases and boxes. Confirm this before you buy—it allows you to purchase a little extra "just in case" without the risk.
- Split your purchase into a core amount and a buffer. Buy the core amount (about 80% of your estimate) upfront, and keep the buffer in reserve to be bought closer to the day if needed.
- Calculate the corkage fee. If your venue charges a fee for bringing your own alcohol, compare the total cost of buying it yourself (including the fee) with the venue's drinks package.
- Don't overdo the variety. Three or four well-chosen options will go down better than ten different types of spirits, half of which will be left nearly full at the end of the night.
- Plan for chilling and logistics. Ice, fridges, and storage space are often the real bottleneck, not the quantity of drinks itself.

The Legal Side — Serving vs. Selling
A quick but important note: if you are providing alcohol to your guests for free as part of a private party, you generally don't need a license. The situation changes if alcohol is being sold (e.g., a cash bar). In that case, the venue or bar service must have the proper licenses to sell alcohol. In practice, at most weddings, the alcohol is provided by the couple or is part of the venue's package. It's always wise to ask your venue about their policy on bringing your own alcohol, corkage fees, and who is responsible for serving it.

Frequently Asked Questions (FAQ)
How much vodka per person for a wedding?
A safe estimate is 0.3–0.5 L per adult guest who drinks alcohol, with 0.4 L being a good starting point. Remember to base this calculation only on the guests who will be drinking, not your entire guest list—exclude children and non-drinkers from the vodka count, but include them when calculating soft drinks and water.
How many soft drinks for a wedding of 100 people?
For 100 guests, plan for around 200 L of soft drinks (2 L per person) and 120 L of water (1.2 L per person), calculated for everyone attending. In the summer or during a heatwave, increase the amount of water and soft drinks by 30–40%, as they will be the first things to run out.
How much alcohol for a wedding of 50 people?
Assuming ~40 adult drinkers: about 32 x 0.5 L bottles of vodka, 20–22 x 0.75 L bottles of wine, 60 bottles of beer, and 7 bottles of champagne for a single toast. On top of that, you'll need ~100 L of soft drinks and ~60 L of water for all 50 guests. Opt for the lower end of this range for a more relaxed celebration.
How much champagne for a wedding toast?
A 0.75 L bottle fills 6–8 flutes, so one bottle is enough for about 6–7 guests for a single toast. For 100 guests, this means you'll need roughly 12–15 bottles. If you're planning two toasts or want champagne to be freely available, you'll need to increase the quantity accordingly.
Is it better to buy our own alcohol or get it from the venue?
It depends on the venue's corkage fee and the price of their drinks packages. Buying your own can be cheaper, but you have to manage the logistics (transport, chilling, returning leftovers) and potentially pay a corkage fee. Always calculate both options and confirm the venue's policy on bringing your own alcohol before you decide. If you buy it yourself, choose a supplier that offers a sale-or-return policy on unopened cases.
