Planning drinks for a summer party is a balancing exercise.

Order too little and the most popular choices may disappear before the event ends. Order too much and you could be left with unnecessary stock, storage pressure and a larger bill than expected.

There is no universal beer, wine and water ratio that suits every London event. Guest preferences, weather, event length and whether food is being served should all shape the order.

Summer Party Drinks Checklist

Begin with the guest list, not the product list

The number of guests is only the starting point.

A daytime garden party may need more water, sparkling drinks and lighter wines. An evening celebration may create stronger demand for beer, wine and mixers.

You should also estimate how many guests are likely to drink alcohol, how many will be driving and whether children or younger guests will attend.

Use ratios as planning guides, not fixed rules

For a mixed adult summer party, a reasonable starting split for the alcoholic portion of the order may be:
  • Around 45% beer and cider
  • Around 40% still wine
  • Around 15% sparkling wine or event-specific drinks

This is not an industry rule or legal formula. It is simply a planning example that should be adjusted around the guests and event style.

A wine-focused lunch may need more white and rosé. A relaxed outdoor party with younger adult guests may require more beer, cider or canned ready-to-drink options.

How much wine should you allow?

A standard 750ml wine bottle normally provides around five 150ml servings.

For an event where wine is one of several drink options, one bottle for every two to three wine-drinking guests may be a reasonable starting estimate. The figure should be increased for a seated meal where wine is served throughout.

White and rosé often perform well during warmer weather, while red wine may account for a smaller part of a daytime summer order.

If sparkling wine is being served for a toast or arrival drink, Should I choose Champagne or Prosecco for an event in London? can help with that decision.

How much beer should you order?

Beer quantities depend heavily on format and event duration.

For a short afternoon event, two or three bottles or cans per beer drinker may be enough. A longer evening party may require more, particularly when beer is the main alcoholic option.

Do not forget alcohol-free beer. It can be useful for drivers, guests who are moderating their intake and people who still want a familiar adult-style serve.

The UK Chief Medical Officers advise that it is safest not to drink more than 14 units per week regularly, spread across three or more days. Event organisers should therefore provide enough non-alcoholic choice and avoid encouraging excessive consumption.

Water should never be treated as an extra

Water needs its own stock calculation rather than being added as an afterthought.

For a summer event, allow at least 500ml to one litre of drinking water per guest, with more available during hot weather, outdoor service or longer functions. This is a planning allowance rather than a fixed legal requirement.

Still water usually accounts for the majority of demand, but sparkling water can add variety and suit dining tables or more formal settings.

Drinkaware recommends alternating alcoholic drinks with water and limiting how much alcohol is consumed on a single occasion.

Do not underestimate soft drinks and mixers

Even an adult-focused party needs a strong non-alcoholic range.

Cola, lemonade, tonic water, soda water and ginger beer can serve several purposes. They work as standalone drinks, cocktail ingredients and alternatives for people who are not drinking alcohol.

A starting point may be to plan at least two or three non-alcoholic servings for every guest, then increase the quantity for children, daytime events or hot weather.

A sample order for 100 guests

For a mixed four-to-five-hour summer party, a starting order might include:
  • 120 to 160 bottles or cans of beer and cider
  • 30 to 40 bottles of still wine
  • 10 to 15 bottles of sparkling wine
  • 60 to 100 litres of still and sparkling water
  • 200 to 300 servings of soft drinks and mixers
  • A separate alcohol-free beer, wine or sparkling option

These figures are planning examples only. They should be adjusted according to the number of drinkers, service format, event length and confirmed guest preferences.

Remember ice, chilling and storage

Having enough drinks is only useful if they can be served properly.

Summer orders may require additional refrigeration, ice and cold-storage space. Larger venues should also decide whether the whole order should arrive at once or be divided into scheduled deliveries.

Keep licensing and age checks in mind

Where alcohol is sold or supplied under a premises licence in England and Wales, the mandatory licence conditions include an age-verification policy. Staff involved in alcohol service should understand and follow the venue’s procedures.

Private hosts should also serve alcohol responsibly and make sure guests have access to food, water and suitable transport arrangements.

Conclusion

A balanced summer drinks order should include enough beer and wine for expected demand without allowing alcohol to dominate the entire selection.

Water, soft drinks, mixers and alcohol-free choices should be planned just as carefully. The most accurate order will come from matching quantities to the guest list, event duration, weather forecast and serving format.
