Who is each format for?
The useful distinction is whether each person will finish a drink at lunch or need to close it and carry it afterwards.
Organisers serving a group
A 24 × 330ml case gives you 24 defined servings and 7.92 litres in total. Joybuy lists that format for Cano Water still ring-pull cans, while South Downs Water lists a case of 24 still-water cans. Count the drinks your group will need rather than assuming one case covers the whole outing.
People carrying a drink after lunch
If a drink may be opened during the meal and carried on a walk, check the closure. The Cano Water 24 × 330ml variants listed by Amazon.co.uk distinguish resealable lids from ring-pull lids; the two should not be treated as interchangeable.
Shoppers choosing a larger bottle serving
If 500ml per person and a conventional closeable bottle suit the picnic better, Tesco and Sainsbury’s list bottle multipacks from brands including Highland Spring, Buxton, Evian and Volvic. Those listings are alternatives to the can format, not canned versions of the same products.
What should you check before buying?
Settle the serving size and closure first. Then check how you will carry the drinks, deal with empties and keep food that needs refrigeration cool.
| Priority | What to check | Your needs |
| Servings | Check the number of drinks and volume per drink. A 24 × 330ml case contains 7.92 litres; a 12 × 500ml pack contains 6 litres. | I’m counting drinks for the group, not just choosing a pack by its size. The length of the picnic and planned activity matter too. |
| Closure | Read the exact variant name for ring-pull or resealable lids. Do not assume every water can closes after opening. | If we’ll finish drinks with lunch, ring-pull servings work for that plan. For drinks carried between stops, I want a closure I can use again. |
| Water and format | Confirm still or sparkling water, and whether the listed multipack contains cans or bottles. Check whether a 330ml or 500ml serving suits the group. | Some guests may want still water; others may prefer sparkling. A larger individual serving could matter more to us than buying cans. |
| Empties | Check for a suitable recycling point at the venue or plan to take empties home. Recycle Now advises emptying and rinsing drink cans before recycling. | We’ll need somewhere to put empty cans during the picnic rather than assuming the venue has a suitable recycling bin. |
| Chilled food | Plan separately for food normally kept in the fridge. Food Standards Agency picnic guidance says to keep it cool; frozen drinks can help keep a cool box cold. | I want cold drinks, but I also need a way to keep picnic food that requires refrigeration cool. |
Brand and retailer references
The named products cover both water cans and bottle multipacks. Check the individual pack format rather than assuming every range includes a canned option.

- The named variants let you choose a closure for drinks finished at lunch or carried after opening.

Picnic water questions
Should I choose ring-pull or resealable water cans?
Choose ring-pull cans if drinks will be finished after opening; look for an explicitly resealable variant if someone may carry an unfinished drink. Amazon.co.uk lists the Cano Water 24 × 330ml ring-pull and resealable-lid variants separately, so check the exact pack.
Can we recycle empty water cans after the picnic?
Yes, but plan where the empties will go. Recycle Now advises emptying and rinsing drink cans and says only some out-of-home recycling points accept them; take them home if the venue has no suitable point.
Do chilled drinks replace a cool box for picnic food?
No. Food Standards Agency picnic guidance says foods normally kept in the fridge also need to be kept cool at a picnic. Frozen drinks can help keep a cool box cold, but they do not remove the need to plan for chilled food.
How many drinks should I pack for a picnic lunch?
Count the people, the servings each may want and the time you will be out. A 24 × 330ml pack contains 7.92 litres, while a 12 × 500ml pack contains 6 litres; neither pack count alone tells you whether it will cover your group’s plans.
