Who is a 2-litre bottle for?

People sharing water at lunch

A 2-litre bottle provides one shared still-water container. If several guests will need more than one bottle, decide whether carrying a multipack is practical.

Shoppers choosing a particular water

If the source, mineral composition or brand matters to you, check the exact bottle size and current retailer listing. A brand’s wider range does not establish that its 2-litre bottle is available where you shop.

Hosts bringing chilled food

Water is only one part of the packing plan when lunch includes sandwiches, salads or dairy foods normally kept in the fridge. Food Standards Agency guidance calls for a cool box or bag with ice or frozen gel packs for those foods.

What should you check before buying?

Start with the amount the group needs and what you can carry, then choose still or sparkling water. Check the exact bottle and its label before packing.

Priority What to check Your needs
Bottle size and pack count Check whether the listing is for one 2-litre bottle or several. Tesco Groceries lists both a single 2-litre still bottle and a 6 x 2L still-water pack; a multipack means more to carry. I want enough water to share, but I need to decide whether one bottle will do or several unopened bottles are worth carrying.
Still or sparkling Check the carbonation type and bottle size separately. Tesco Groceries lists a 2-litre sparkling option, while Highland Spring lists different sizes for its sparkling range. If the group wants bubbles with lunch, I’ll look for sparkling water rather than assume a still-water multipack suits everyone.
Chilled-food packing For food normally kept in the fridge, the Food Standards Agency advises a cool box or bag with ice or frozen gel packs. It suggests separating drinks and perishable food when using more than one cooler. Lunch includes chilled food, so I need room to keep it cool even if the drinks are packed elsewhere.
Exact bottle and label Confirm the retailer’s current listing and read the bottle label for storage instructions. Tesco’s 6 x 2L still-water listing says opened bottles should be refrigerated and consumed within 3 days. A particular brand or mineral composition matters to me, and I want to know how to store any bottle left open after lunch.

What can go wrong when packing water?

  • Planning around a bottle that is not in stock

    Tesco Groceries marked its Evian 2-litre listing out of stock when it was reviewed. A product listing or a brand range does not confirm that you can buy that bottle for this picnic.

    Check the exact retailer listing when you shop, and have another acceptable format in mind if the bottle you wanted is unavailable.

  • Using a water bottle in place of cold storage

    Food normally kept in the fridge still needs to be kept cool at a picnic, according to the Food Standards Agency.

    Use a cool box or bag with ice or frozen gel packs for chilled food. If you have two coolers, consider putting frequently accessed drinks in the other one.

  • Assuming every brand sells the size you need

    A brand may appear in the bottled-water aisle without the particular 2-litre format you want. For example, the cited Tesco listing for Volvic is 1L, while its cited Buxton listing is a 6 x 1.5L pack.

    Read the capacity and pack count on the exact product listing rather than choosing by brand name alone.

  • Overlooking instructions on the bottle

    Storage and recycling directions can be specific to the product. Tesco’s 6 x 2L still-water listing includes instructions for both opened bottles and packaging.

    Check the label on the bottles you buy, particularly if some water will be left after the picnic.

Which brands and ranges are relevant?

These range examples can help you identify a bottle size to look for; they do not establish what your chosen shop has in stock.

Tesco

Tesco Groceries lists own-label still and sparkling water in 2-litre bottles, as well as a 6 x 2L still-water pack.

  • The listings distinguish a single bottle from a pack of six.
  • Check the current listing and the bottle label when buying.

Highland Spring

Highland Spring’s still-water range lists a 2L screw-cap bottle alongside smaller sizes.

  • The brand’s range identifies the 2L still-water format.
  • Confirm the exact bottle with your retailer before planning around it.

Evian

Tesco Groceries has a listing for Evian Natural Mineral Water in a 2-litre bottle, including mineral-composition information.

  • The listing identifies the bottle size and composition for shoppers comparing labels.
  • Tesco marked that listing out of stock when it was reviewed; check current availability.

Volvic

The cited Tesco Groceries listing identifies a 1L Volvic natural mineral-water bottle and gives mineral-composition information.

  • The 1L listing provides a specific bottle size to compare with your packing plan.
  • Check an exact product listing if you need a 2-litre bottle.

Buxton

Buxton appears in the cited Tesco Groceries water category as a 6 x 1.5L still-water pack.

  • A pack of smaller bottles may suit a plan based on separate containers.
  • That listing is not evidence of a 2-litre Buxton bottle; check capacity before buying.

Sainsbury's

Euromonitor International’s November 2025 UK bottled-water report identifies Sainsbury's among private-label retailers in the category.

  • Its own-label range is another retailer route to check.
  • Confirm the bottle size on a current product listing if 2 litres is essential.

White Rock Still Spring Water 6 x 2L

Six 2-litre bottles provide a shared still-water supply, with unopened bottles to set aside if the whole pack is not needed at lunch. The pack contains 12L in total and will be bulkier to carry than a single bottle. Check the bottle label for instructions after opening.

Picnic water questions

Does bringing bottled water keep chilled picnic food safe?

No. Food Standards Agency guidance for England, Northern Ireland and Wales says food normally kept in the fridge should be kept cool at a picnic. Use a cool box or bag with ice or frozen gel packs; if you have more than one cooler, you can keep drinks and perishable food separate.

Can frozen drinks help cool a picnic box?

Yes. The Food Standards Agency says frozen drinks can help keep a cool box cold. They do not remove the need to pack foods normally kept in the fridge so that those foods stay cool.

How should I store an opened 2-litre bottle after the picnic?

Follow the instructions on that bottle. For Tesco British Natural Mineral Water Still 6 x 2L, Tesco Groceries says to refrigerate an opened bottle and consume it within 3 days; instructions for another product may differ.

Can a 2-litre water bottle be recycled after use?

Check the instructions on the exact bottle and your local collection arrangements. For its British Natural Mineral Water Still 6 x 2L product, Tesco Groceries says to recycle the bottle with its cap on at a large supermarket rather than at home.
