What should you check before buying?
Start with the milk type in the recipe, then choose a pack quantity that fits the bake and your likely use after opening.
| Priority | What to check | Your needs |
| Milk type and size |
Read the milk type and volume on the same label. Tesco and Sainsbury's list four-pint skimmed milk alongside six-pint semi-skimmed milk. |
I need skimmed milk, so a larger bottle labelled semi-skimmed would not meet that requirement. |
| Recipe substitution |
Check whether the recipe specifies skimmed, semi-skimmed or whole milk. If it specifies a type, do not change it solely to obtain a larger bottle. |
If the bake relies on a stated milk type, I would rather adjust the number of packs than make an unplanned substitution. |
| Pack format |
Distinguish one six-pint bottle from multiple smaller cartons. Check the volume of each unit and the number of units in a multipack. |
Several cartons could suit separate baking days, while one bottle suits a session that needs a larger amount at once. |
| Storage after opening |
Follow the particular pack's refrigeration, opened-life and date instructions. Sainsbury's six-pint semi-skimmed milk says three days after opening; Tesco's says it is best within five days and by its use-by date. |
I want a quantity we can use within the instructions on the bottle we actually buy. |
| Milk allergy |
Check the current ingredient and allergen label. The Food Standards Agency identifies milk as an allergen; NHS guidance distinguishes cow's-milk allergy from lactose intolerance. |
Where a child has a known or suspected cow's-milk allergy, I cannot assume ordinary, filtered or lactose-free cow's milk is a suitable substitute. |
Relevant brand ranges
These retailer listings illustrate the difference between skimmed pack sizes and larger bottles; check the exact product label when buying.
Tesco
Tesco lists British skimmed milk in one-, two- and four-pint sizes, and a separate six-pint British semi-skimmed milk.
- The four-pint listing offers a skimmed option when that is the milk type the recipe calls for.
- The cited six-pint product is semi-skimmed, so it is not the same milk type in a larger bottle.
Sainsbury's
Sainsbury's lists four-pint British skimmed milk and six-pint British semi-skimmed and whole milk.
- The range offers different milk types and capacities to check against a recipe.
- Its cited six-pint semi-skimmed product says to consume it within three days of opening.
M&S
M&S lists a 2.272L, four-pint Scottish skimmed milk and describes it for use in recipes.
- The identified four-pint product keeps the choice focused on skimmed milk.
- Confirm the exact pack size on the product you select rather than assuming a larger listed milk is also skimmed.
Waitrose
Waitrose lists filtered British skimmed milk in a two-litre pack.
- Its product instructions specify refrigeration below 5°C and consumption within seven days of opening.
- Two litres is not a six-pint bottle; check whether that quantity fits the planned bake.
Cravendale
The Cravendale product listed by Waitrose is two-litre filtered semi-skimmed milk.
- The brand's listing states up to three weeks unopened and seven days after opening; follow the pack's storage and date instructions.
- This product is neither skimmed milk nor a six-pint pack.

Frequently asked questions
Do Tesco, Sainsbury's or M&S list six-pint skimmed milk?
The cited Tesco and Sainsbury's ranges list skimmed milk up to four pints, while their six-pint products are labelled semi-skimmed; Sainsbury's also lists six-pint whole milk. M&S lists a four-pint skimmed product. Those listings cannot establish what every shop stocks, so check the milk type on any six-pint pack you find.
Can I replace skimmed milk with six-pint semi-skimmed milk in a bake?
Consider the substitution only if the recipe allows a different milk type. Tesco and Sainsbury's label the cited six-pint bottles semi-skimmed, not skimmed; if a recipe specifies skimmed milk, following that instruction avoids changing the ingredient simply to obtain a larger pack.
How long can an opened six-pint bottle be kept?
Follow the instructions on the bottle you buy. Sainsbury's cited six-pint semi-skimmed milk says to refrigerate it below 5°C and consume it within three days of opening; Tesco's six-pint semi-skimmed milk says it is best within five days of opening and must be used by the date shown.
Is lactose-free cow's milk suitable for a child with cow's-milk allergy?
Do not assume it is suitable. NHS guidance distinguishes cow's-milk allergy, which concerns milk proteins, from lactose intolerance. For a child with a known or suspected allergy, follow their clinician's advice and check the ingredients and allergen label.
