Choosing ready-to-drink cocktails in the UK should be simple: select a flavour you enjoy, check the alcohol content and chill it before serving. However, attractive packaging and familiar cocktail names can make it difficult to compare products fairly. A can labelled “martini” or “mojito” may differ significantly in strength, serving size, sweetness and storage requirements.
This guide explains the practical details to check before buying premixed cocktails, whether you are planning a barbecue, picnic, festival, party or relaxed evening at home.
A lower-looking percentage does not always mean less alcohol overall. A 330ml can at 6% ABV contains around 2 UK units, while a smaller 125ml cocktail at 14.9% ABV contains approximately 1.9 units. Always consider both ABV and container size.
For reference, the UK Chief Medical Officers advise that adults should not regularly exceed 14 units per week. Alcohol should be avoided during pregnancy, and you should never drink before driving or operating machinery.
Some canned cocktails are designed to drink straight from the can, while others are more enjoyable poured over ice. Bottled cocktails may need refrigeration after opening, and cream-based liqueurs have different storage requirements from carbonated drinks.
Check the serving instructions before ordering. This is particularly important if you are buying for an outdoor event without access to a fridge or ice.
Fruit-flavoured alcoholic drinks can range from sweet and lemonade-based to dry and citrus-led. Ingredient lists may include sugar, sweeteners, sulphites, milk or caffeine. These details matter when you are buying for several guests with different preferences.
Do not rely on words such as “light”, “fresh” or “smooth” alone. Compare the nutritional panel and allergen information on the product page or packaging.
ABV means alcohol by volume. It helps you compare strength, but UK units provide a clearer indication of the alcohol in a serving. The approximate formula is:
ABV × volume in millilitres ÷ 1,000 = UK units
For example, a 250ml drink at 5% ABV contains approximately 1.25 units. Product labels may round this figure, so use the stated packaging information when available.
The selection of ready-to-drink alcoholic drinks includes lower-strength 3.4% options, familiar 4–5.4% mixed drinks and stronger cocktail-style serves at around 8–14.9% ABV.
A single-serve cocktail is convenient for individual use, while larger packs can be more suitable for sharing. Common formats include:
For a picnic or festival, cans are easy to transport and do not require glassware. At home, bottled cocktails and larger-format drinks can work well when served over ice.
Choose the base spirit first, then the mixer or fruit profile. Premixed vodka drinks often pair vodka with lemonade or passion fruit. Premixed rum drinks commonly use cola, pineapple, strawberry or lime. Citrus-led drinks may taste sharper and drier, while coconut, cream and berry combinations tend to be sweeter.
Look for named ingredients rather than relying only on cocktail titles. Check for:

Before you buy cocktails online in the UK, use this checklist:
They can be convenient for parties because they require no measuring, shaking or specialist equipment. Select a mixture of strengths and flavours, provide non-alcoholic alternatives and keep drinks chilled where recommended. Hosts should also monitor responsible serving and ensure alcohol is not supplied to anyone under 18.
The answer depends on the recipe, spirit and quantity required. Premixed cocktails include the cost of preparation and convenience, while homemade drinks may offer more control over ingredients and serving size. For a small gathering, single-serve cans can reduce the need to buy several full-size bottles and mixers.
Follow the product label. Unopened drinks are commonly stored in a cool, dry place away from direct sunlight, but some bottled cocktails require refrigeration after opening and should be consumed within a specified period. Always check the individual product instructions rather than assuming every RTD cocktail has the same shelf life.
