How Much Alcohol for a Villa Party in Phuket: A Calculator for 10, 20 and 40 Guests

How much alcohol for a party of 20? A good starting point is about three drinks per guest over four hours, then a split into beer, wine and spirits. For a villa party that means 24 cans of beer, 4 bottles of wine and 2 bottles of spirits for 20 guests, plus mixers and ice, and ALCOSHOP Phuket can deliver the whole list to your villa in one order.

This guide is for hosts planning a villa evening with 10 to 40 adult guests (20+). The numbers sit in one table, the calculator, and the assumptions behind them are written out so you can change them for your own crowd. Everything here is a planning guide, not a target: many guests drink less or nothing at all.

Quick answer: how much alcohol per guest

If you only read one section, read this one.

• Plan about 3 drinks per guest for a 4-hour party. It is a planning average, not a norm and not a goal. Part of any group drinks slowly or does not drink, and the average already counts them.
• Split the drinks 40 / 30 / 30: 40% beer, 30% wine, 30% spirits.
• Round bottles and packs up. The table below is already rounded up to whole packs.
• Ice, mixers and water are separate lines. Mixers are counted only for spirits; ice is a range in kilograms; water has no number because it should be more than you think.
• Adults only (20+), with food and a ride home planned. The safety section below covers the basics.

The calculator: 10, 20 and 40 guests

Per party	10 guests	20 guests	40 guests
Total drinks (3 per guest)	30	60	120
Beer, 0.33 l (cans/bottles)	12	24	48
Wine, 0.75 l (bottles)	2	4	8
Spirits, 0.7 l (bottles)	1	2	3
Mixers, 0.33 l (cans)	5	9	17
Ice (kg)	5–10	10–20	20–40

These are our planning assumptions for a four-hour evening with adult guests. Shift them up or down for your own group using the next sections.

How to read the table: find your guest count, take the row for each drink, and buy that number or the next full pack. A “drink” here means one serving: a 0.33 l can of beer, a glass of wine or a measure of spirits. Water is missing on purpose, see Mixers, ice and water.

Our planning assumptions

The model is simple arithmetic, so you can check every number.

• Reference serving. In the US, a standard drink is about 14 g of pure alcohol: roughly 355 ml of 5% beer, 150 ml of 12% wine or 44 ml of 40% spirits (NIAAA). Serving sizes differ by country, so we use one reference size and call it an assumption.
• Length. A common party-planning rule of thumb is 2 drinks per guest in the first hour, then 1 per hour, which is about 5 drinks in four hours for a guest who drinks throughout. It is a planning guide, not a health guideline. We plan on 3 drinks per guest on average, because part of the group drinks little or nothing (our assumption).
• Shares. 40% beer, 30% wine, 30% spirits (our assumption).
• Beer. One 0.33 l can or bottle per serving.
• Wine. A 150 ml glass; a 0.75 l bottle pours about 5 glasses.
• Spirits. A 0.7 l bottle holds about 16 measures of 44 ml (our calculation from the reference serving). With a 50 ml pour, it is 14.
• Mixers. One cocktail takes about 150 ml of mixer, so one 0.33 l can covers about two. Mixers are counted for spirits only; beer and wine need none.
• Ice. Ice suppliers suggest about 1–2 lb (0.5–1 kg) per guest. In Phuket heat, plan toward the upper end or more (our assumption).
• No buffer. The table is rounded up to whole packs but has no reserve. If you want a safety margin, add one pack per category.

Check for 20 guests: 60 drinks, of which 40% beer is 24; 30% wine is 18 glasses, or 4 bottles after rounding; 30% spirits is 18 measures, or 2 bottles; 18 cocktails at 150 ml is 2.7 l, or 9 cans.

How to adjust the numbers for your party

The table fits an average four-hour evening. Real parties differ, and the fix is usually a simple multiplication.

• Longer or shorter party. Scale in proportion. A six-hour party is 1.5 times the table; a two-hour one is about half, with a little extra in the first hour.
• If everyone drinks. Using the “2 in the first hour, then 1 per hour” rule, a drinking guest has about 5 drinks in four hours. Multiply the table by 5/3 (about 1.7). For 20 guests that is 100 drinks: 40 beers, 6 bottles of wine and 2 bottles of spirits (30 measures).
• Birthday or evening cocktails. Shift toward spirits and mixers: for example 30% beer, 30% wine, 40% spirits, and add mixers and ice accordingly.
• Daytime pool party. Beer, light wine and sparkling go faster in the heat. Keep the beer share, add ice and water.
• A wine or beer crowd. Move 10 points between categories, then recalculate: drinks × share ÷ serving size.
• Heat. Ice and cold drinks go quickly outdoors. Take the upper end of the ice range, and more water.
• Unknown guest count. Plan for the confirmed number plus about a fifth, and order the stable items (beer, mixers) a little higher than the fragile ones.

Example: 25 guests, four hours. 25 × 3 = 75 drinks. Beer 40% = 30 cans. Wine 30% = 22.5 glasses, about 4.5 bottles, so 5. Spirits 30% = 22.5 measures, about 1.4 bottles, so 2. Cocktails 22.5 × 150 ml = 3.4 l of mixer, so 11 cans. Ice 12.5–25 kg.

Beer, wine, spirits: what to choose for a villa party

The table says how much; this section is about what. We do not compare brands or prices here, only the logic of a sensible villa shelf.

Beer

Pick a light lager that is good very cold. In the heat, beer that is only cool goes flat in the glass, so the cold chain matters more than the label. Cans pack neatly into a cooler box and are easy to carry around the pool; bottles need a safe place away from the water’s edge. Browse the beer category for what is in stock. Which lager suits the heat: our guide to Thai beer.

Wine

White, rosé and sparkling suit a hot evening better than heavy reds. Buy by bottles: 0.75 l is about 5 glasses. If the party is mostly wine, buy glasses too (stemless or plastic by the pool) and chill the bottles a day ahead. See the wine category.

Spirits and cocktails

One or two base spirits beat six half-used bottles. A simple mix works for most groups: one vodka or gin for tonic and soda, one whiskey or rum for cola. Do not chase the most expensive bottle; at a party with mixers, the extra price rarely shows in the glass. Price ranges are in our guide to alcohol prices in Phuket. The categories are vodka, whiskey, rum, gin and tequila.

Mixers, ice and water

This is the part hosts forget, and the part that runs out first.

Mixers to buy:

• Tonic for gin and vodka;
• cola for whiskey and rum;
• soda water for long drinks;
• juice for people who want a color in the glass without the spirit.

Our catalog has mixers: tonic, cola and 1 l juice. Buy more cola or tonic than you expect; they are the cheapest way to stretch spirits without anyone feeling short.

Ice, two jobs:

• For chilling. Ice in the cooler box that keeps beer, wine and water cold. Layer ice and drinks, and top up as it melts.
• For glasses. Ice for cocktails and soft drinks. The table range of 0.5–1 kg per guest covers both; in heat, take the top of the range.

Water and soft drinks:

• Keep more water than you think you need, and more again if the party is outdoors in the sun.
• Put bottles of water in every area where people gather, not just in the kitchen.
• Add juice, soda and one or two non-alcoholic options so that guests who do not drink are not left with tap water.

Ice and drinking water are not in our catalogue, so pick them up at a nearby shop on the day; everything else comes in one ALCOSHOP order.

Logistics at the villa: cooling, storage, timing

A well-calculated party can still go wrong if the drinks are warm or locked behind a gate.

Cooling and storage:

• Count the fridge space before you order. Beer for 40 guests is 48 cans, which will not fit in a kitchen fridge.
• Use cooler boxes or large tubs for the rest, and put them in the shade.
• Chill wine and beer a day ahead; ice alone will not cool a warm case in time.
• Keep spirits and mixers away from the pool edge, on a table or bar area.
• Keep glass away from the water and use plastic cups by the pool.

Receiving the order:

• Tell the villa staff or manager that a delivery is coming and who accepts it.
• Check gate and access rules, especially in gated villa areas.
• Give the courier a clear contact for the day.
• Unpack and check the order against your list as soon as it arrives.

Timeline checklist:

• Three days before: confirm the guest count, finish the list from the table, check fridge and cooler space, decide on glasses and cups.
• One day before: have the drinks on site, chill beer, wine and mixers, buy ice and water, confirm transport home for guests.
• Three hours before: fill the cooler boxes with ice and drinks, set up the bar, put out water and food, charge phones for taxi apps.

Villa areas we cover: Kamala, Bang Tao, Laguna, Rawai and Surin.

Safety and responsible hosting

A party is a good one when everyone gets home well. Some practical rules for the host:

• Guests are adults, 20 and over. Thai law sets the minimum age for buying alcohol at 20.
• Alternate with water. Put water within reach of every drink station and encourage guests to take a glass between drinks.
• Serve food. Eat before and during the party. Add food, pizza or fruit to the order.
• Keep pool and alcohol apart. Heat, water and drinking do not mix well; keep a sober person watching the pool and do not pressure anyone to swim.
• Plan the ride home. Arrange taxis, a transfer or a sober driver before the party starts. WHO notes that the risk of a road crash begins at low blood-alcohol levels.
• Never push anyone to catch up. Let guests set their own pace, and do not top up glasses unasked.
• Offer real non-alcoholic options. Water, juice, soda and mocktails, not only as an afterthought.
• Keep alcohol out of reach of children.
• Know who to call. Save the villa manager’s number and the local emergency services in your phone before the party. If a guest feels unwell, get help early.

Plan your party around Thailand’s dry days

A few times a year, alcohol is not sold in shops across Thailand for a full day because of Buddhist holidays. If your party falls on or near such a day, order everything from ALCOSHOP the day before and check this year’s dates. The full rules and the dates are on our page about Thailand alcohol ban days.

For a party the day after a dry day, plan the same way: do not leave the drinks for the last evening.

Frequently asked questions

How much alcohol do I need for 20 guests?

For a four-hour party, plan 60 drinks: 24 cans of beer, 4 bottles of wine and 2 bottles of spirits, plus 9 cans of mixers and 10–20 kg of ice. See the calculator for 10 and 40 guests too. It is a planning average; adjust it for your group.

How many bottles of wine per person for a party?

A 0.75 l bottle pours about 5 glasses. If wine is 30% of the drinks, that is roughly one bottle for every 5 guests over four hours. If the party is mostly wine drinkers, raise the share and recalculate. What to pick, from prosecco to champagne: our guide to wine and champagne delivery.

How much beer for 40 people?

Plan 48 cans or bottles of 0.33 l as a planning average. Take more if the party is hot, long or mostly beer drinkers, and cool them well in advance.

How much ice do I need for a party?

Ice suppliers suggest about 0.5–1 kg per guest. In Phuket heat, take the upper end or more. Keep ice for chilling the cooler box separate from ice for the glasses.

What is a good drink for a birthday party?

Keep it simple: one or two base spirits (vodka or gin, whiskey or rum), a wine, a light beer and a non-alcoholic option. Add tonic, cola and soda, and you cover most tastes without a long list.

How many mixers per bottle of spirits?

A 0.7 l bottle is about 16 measures. At 150 ml of mixer per cocktail, that is about 2.4 l, or 8 cans of 0.33 l after rounding up. Mixers are counted for spirits only.

Should I buy in advance if a dry day is near?

Yes. On a dry day, alcohol is not sold in shops for a full day, so order from ALCOSHOP the day before. See Thailand alcohol ban days for the rules.

How early should I order for a party?

Order early enough that the list is complete and there is time to chill everything. A settled list a day or two ahead leaves room for changes.

Do I need non-alcoholic drinks?

Yes. Water, juice and soda are part of the plan, not an extra. Some guests do not drink, and everyone needs water in the heat.

What if the party runs longer than planned?

Recalculate by hours: each extra hour is about one drink per guest who is still drinking. Buy ice and water first, since they run out sooner than anything else.
