For a picnic needing about six pints, four 1-litre bottles provide 4 litres and make sense when you can serve drinks in cups; separate bottles suit guests who need individual portions, but you will need more containers. Six pints is approximately 3.408 litres, so check the total pack volume rather than assuming one family bottle will cover it. Keep dairy drinks that require refrigeration in a cool bag or cool box with ice or frozen gel packs until serving.
If your picnic calls for about six pints of milkshake, compare the combined volume of the bottles you plan to buy with approximately 3.408 litres. The choice between larger bottles and individual portions also affects how you will serve them.
Separate bottles avoid pouring from a shared container. Tesco Groceries lists Müller Frijj in 330ml bottles and a Mars chocolate-flavoured milk drink in 400ml bottles; check how many you need for the group.
If the drinks need refrigeration, plan how to keep them cold on the journey and at the picnic. The Food Standards Agency advises packing dairy products in a cool bag or cool box with ice or frozen gel packs.
Decide whether you will pour drinks into cups or hand out separate bottles, then check the combined volume and the storage instructions for the packs you choose.
Choose when: Your group can share from cups and you can keep bottles cold where required.
Trade-off: You need cups, and an opened bottle may need continued chilled storage.
Choose when: Guests need separate drinks without pouring from a shared bottle.
Trade-off: Reaching the group volume means carrying more bottles and packaging.
| Priority | What to check | Your needs |
|---|---|---|
| Total volume | Six pints is approximately 3.408 litres, using the 568ml pint size shown by Tesco Groceries. Three 1-litre bottles provide 3 litres; four provide 4 litres. | I need enough for the whole group, so I’ll add up the stated bottle volumes before choosing a pack count. |
| Portion size | Tesco Groceries lists 330ml Müller Frijj bottles and a 400ml Mars drink. Eleven 330ml bottles provide 3.63 litres; nine 400ml bottles provide 3.6 litres. | Separate drinks would make serving easier at our picnic, but I still need the combined volume to reach roughly six pints. |
| Chilled storage | Read the pack’s storage instructions. For dairy drinks that require refrigeration, the Food Standards Agency advises a cool bag or cool box with ice or frozen gel packs for a picnic. | I’ll be travelling and waiting outdoors before serving, so I need a way to keep refrigerated drinks cold. |
| Ingredients and allergens | Check the ingredient and allergen information on each current pack, particularly if buying different flavours or formats. | Someone in the group may need to check a particular ingredient; a brand or flavour name alone won’t answer that question. |
A six-pint target is approximately 3.408 litres. The 1-litre milkshake and flavoured-milk formats listed by Tesco Groceries each cover less than a third of that amount.
Add up the bottle sizes before buying: three 1-litre bottles fall short, while four provide 4 litres.
Drinks that must be kept chilled still need suitable storage during travel and while waiting to be served outdoors.
Follow the pack instructions. For refrigerated dairy drinks, use a cool bag or cool box with ice or frozen gel packs, as the Food Standards Agency advises for picnics.
Individual portions vary in size: nine 400ml bottles total 3.6 litres, whereas nine 330ml bottles total only 2.97 litres.
Multiply the volume on the pack by the number of bottles. To reach approximately six pints with 330ml bottles, you need eleven.
Ingredients and allergen information belong to the specific product and pack, not to a flavour name shared by different drinks.

These examples describe formats listed by Tesco Groceries, not the full range available from each brand or retailer.
Tesco Groceries lists 1-litre Yazoo chocolate and banana milkshakes, making the listed format relevant when serving a group from larger bottles.
Tesco Groceries lists a 330ml Müller Frijj chocolate milkshake, a format to consider when guests need separate bottles.
Tesco Groceries lists a Mars chocolate-flavoured milk drink described as no added sugar in a 400ml format.
Tesco Groceries lists its own-label chocolate-flavoured milk in a 1-litre bottle, another larger format for a shared drink supply.
This option is a multipack of individual, ready-to-drink protein nutrition shakes described as milkshake-style. Check whether that type of drink suits your picnic rather than treating it as a conventional milkshake.

Eight separate 500ml bottles provide 4 litres in total, exceeding an approximate six-pint group target. This is a ready-to-drink protein nutrition shake described as milkshake-style, rather than a confirmed conventional milkshake. Check the pack’s storage instructions before planning how to transport unopened bottles, and follow its instructions after opening.
Six pints is approximately 3.408 litres, using the 568ml one-pint pack size shown by Tesco Groceries. Three 1-litre bottles provide only 3 litres; four provide 4 litres.
A 1-litre bottle cannot cover an approximately 3.408-litre requirement on its own. Tesco Groceries lists relevant 1-litre milkshake and flavoured-milk formats, so check the volume of any larger bottle you consider rather than assuming its label or description means six pints.
Follow the storage instructions on the drinks you buy. For dairy drinks that need refrigeration, the Food Standards Agency advises using a cool bag or cool box with ice or frozen gel packs at a picnic; keep drinks chilled until they are needed.
Yes. Check the ingredient and allergen information on each current pack before serving someone who needs to avoid an ingredient. Do not assume that different flavours, bottle sizes or drinks from the same brand have identical ingredients.
