One-tin shoppers
You need one tin for a meal rather than a multipack. Tesco Groceries, Sainsbury’s and ASDA Groceries each list a single 145g tin of tuna chunks in spring water.
Who is choosing a single tin?
Drained-weight comparers
You want to know how much tuna remains once the packing liquid is removed. Check the drained weight on the exact tin: net can weights alone do not give that comparison.
Label-led shoppers
You choose according to packing liquid, the stated nutrition or sourcing details, and what you will do with any leftovers. Read the current label for the particular product you pick.
What matters when choosing?
| Concern | What to check | Who this matters to |
|---|---|---|
| One tin rather than a multipack | Confirm the listing is for one tin and that its packing liquid suits your meal. | If I only need tuna for one meal, I do not want to take home several tins. About 36% of consumers put buying just one tin first. |
| Usable amount | Compare drained weights, not only the net weights printed on cans. | When I am planning a portion, I need to know how much fish I can use after draining. For about 29% of consumers, usable amount is the primary concern. |
| Meal and label fit | Check chunks versus flakes or steak, the packing liquid, and nutrition figures on the exact tin. | If a recipe calls for plain chunks, a seasoned flake product may change the dish. About 21% of consumers chiefly consider the format and label details needed for their meal. |
| Sourcing and leftovers | Read any catch-method statement and the product’s own after-opening instructions. | I may want a particular sourcing statement or need to store part of the tin after opening. Those are the leading needs for about 14% of consumers. |
Checks that are easy to miss

Judging the amount of tuna by can size
A larger net weight does not necessarily mean more drained tuna. Tesco Groceries lists its 145g spring-water tin at 102g drained, while the John West 125g single tin listed by Waitrose & Partners also states 102g drained.
Use the drained weight when the amount of fish matters to your meal, and compare tins in a suitable format and packing liquid.
-
Assuming spring-water tins have identical labels
The packing liquid alone does not tell you the tin’s stated salt figure or all its ingredients.
Read the nutrition and ingredients panels on the exact product, using the same per-100g basis when comparing figures.
-
Keeping leftovers in the opened can
The retailer listings give product-specific instructions for transferring leftover tuna to another container and refrigerating it.
Follow the storage and use-by directions on the tin you open.

Frequently asked questions
Should I compare a tuna tin’s net weight or drained weight?
Use drained weight to compare the amount of tuna left after removing the packing liquid. Tesco Groceries lists 102g drained for its 145g spring-water tin, while Waitrose & Partners lists 102g drained for a John West 125g spring-water tin.
How should I keep tuna left over from an opened tin?
Follow the exact tin’s after-opening directions. The retailer listings for these single tins instruct shoppers to transfer leftovers to a non-metallic container and refrigerate them; use the interval stated on your product’s label.
Does a sourcing statement apply to every tin from the same brand?
No: check the statement on the particular product you choose. Sainsbury’s describes its listed 145g spring-water tin as pole-and-line caught and MSC certified, but that description should not be applied to every tin in its range.
