What should you check before buying?
Decide whether skimmed milk or a 6-pint bottle is the firmer requirement. Then compare the pack format with how much milk your household expects to use after opening.
| Priority | What to check | Your needs |
| Milk type |
Read “skimmed” or “semi-skimmed” on the bottle. Dairy UK’s milk composition table gives 0.3g fat per 100ml for skimmed milk and 1.8g per 100ml for semi-skimmed milk. |
I want skimmed milk, so I would not swap to a 6-pint semi-skimmed bottle just to get the larger size. |
| Pack size |
Compare the stated volume and container: the cited fresh skimmed listings include 4 pints, or 2.272L, while cited 6-pint semi-skimmed bottles hold 3.408L. Check whether a multipack contains separate cartons. |
Several people may use milk, but I want the quantity and format to match our first shop, not just a large number on the listing. |
| Storage |
Check the exact bottle’s refrigeration and after-opening instructions. Sainsbury’s says to consume its 6-pint semi-skimmed milk within 3 days of opening; Tesco says its 6-pint semi-skimmed milk is best within 5 days and by the use-by date. |
If our milk use is uncertain, I would rather choose a quantity we expect to finish within that product’s stated period. |
| Label details |
Check the date mark and allergen information on the bottle received or selected in store. GOV.UK distinguishes safety-related use-by dates from quality-related best-before dates. |
I need to check the actual label, particularly when a household member has a milk allergy or the date affects when we will use it. |
Brand and retailer references
These examples help distinguish the milk types and pack sizes; a brand name alone does not establish what is in a particular bottle.
Tesco
Tesco Groceries lists British skimmed milk in a 4-pint bottle and a separate British semi-skimmed milk product in a 6-pint bottle.
- The listed 6-pint semi-skimmed bottle holds 3.408L.
- Its product information says it is best used within 5 days of opening and by the use-by date; it is not a skimmed-milk substitute.
Sainsbury’s
Sainsbury’s lists a 4-pint British skimmed milk bottle alongside a 6-pint British semi-skimmed bottle.
- The separate listings make it possible to choose by milk type or by the larger pack size.
- Sainsbury’s says to keep its 6-pint semi-skimmed bottle below 5°C and consume it within 3 days of opening.
Asda
ASDA Groceries lists British semi-skimmed milk in a 6-pint bottle.
- The listed semi-skimmed pack states a 6-pint volume.
- Its label information calls for refrigeration below 5°C; check the milk type rather than assuming a 6-pint bottle is skimmed.
M&S
Ocado lists an M&S 6-pint semi-skimmed bottle and a separate 4-pint M&S skimmed option.
- The 6-pint semi-skimmed product is stated as 3.408L.
- M&S product information says that bottle is best consumed within 3 days of opening.
Waitrose
When browsing Waitrose milk, choose by the milk type shown on the particular product, not by bottle size alone.
- A skimmed-milk choice can be considered separately from a 6-pint semi-skimmed choice.
- Do not treat the two descriptions as an interchangeable 6-pint skimmed product.
Cravendale
Cravendale filtered skimmed milk is listed in smaller 1L and 2L formats on Ocado.
- Separate smaller cartons offer a different pack-size choice from a single 6-pint bottle.
- Waitrose’s statement of up to 7 days after opening applies to a Cravendale filtered semi-skimmed product; check the exact skimmed carton’s label for its own instructions.

Questions about pack size and storage
Should I buy a 6-pint bottle if I want skimmed milk?
Buy a bottle labelled skimmed if milk type is your priority. Tesco, Sainsbury’s and Ocado list 4-pint fresh skimmed options, while the cited 6-pint products are semi-skimmed; check the exact product listing before substituting one for the other.
Is semi-skimmed milk the same as skimmed milk in a larger bottle?
No. Dairy UK’s milk composition table gives 1.8g fat per 100ml for semi-skimmed milk and 0.3g per 100ml for skimmed milk. A 6-pint semi-skimmed bottle changes both the milk type and, compared with a 4-pint skimmed bottle, the quantity.
How long can I keep a large fresh-milk bottle after opening?
Follow that bottle’s label rather than a single period for all milk. Sainsbury’s specifies consumption within 3 days of opening for its 6-pint semi-skimmed product; M&S says its 6-pint product is best consumed within 3 days, while Tesco says its equivalent is best within 5 days and by its use-by date.
What does the use-by date tell me?
GOV.UK says use-by dates relate to food safety, whereas best-before dates relate to quality. Check which date appears on your milk and follow the product’s storage and after-opening instructions as well.
Does skimmed milk avoid a milk-allergen concern?
No: “skimmed” describes the milk type, not an absence of milk. Sainsbury’s identifies milk as an allergen on its cited semi-skimmed product; anyone shopping for a household member with a milk allergy should check the current label of the exact product.
