Christmas meal planners
If the tuna might go into pasta, jacket potatoes, sandwiches or salads, spring-water chunks give you a plain ingredient to use across those plans. Choose the number of tins around the meals you expect to make.
Who is stocking the cupboard?
Household cupboard stockers
If you are stocking up for visitors or the days after Christmas, count the drained tuna rather than relying on the size printed on a tin. Separate cans can remain unopened until each meal needs one.
Label-first shoppers
If you are buying for guests or have a particular fishery-sourcing preference, inspect the exact pack. Its ingredient and allergen information, sourcing statements and instructions for opened tuna matter more than assumptions about a whole brand range.
What matters when choosing tuna?
Decide which issue will determine this purchase, then check the corresponding detail on each tin you are considering.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable quantity | Check drained weight and whether the planned meals call for separate tins or one larger can. Tesco Groceries lists 102g drained weight for its 145g spring-water tin and 280g for its 400g can. | If several festive and post-Christmas meals are planned, I need enough tuna after the liquid is drained without opening more than we can use. About 29% of consumers put usable quantity first. |
| Packing liquid | Choose spring water, brine or sunflower oil for the intended recipe; inspect the ingredients and nutrition panel on the exact pack. | When the same cupboard tin might become a sandwich filling or go into a cooked dish, I want a liquid that fits what I am making. For about 29% of consumers, recipe fit is the primary concern. |
| Ingredients and nutrition | Read the ingredient list and compare nutrition figures on the same per-100g basis, noting whether the label specifies drained tuna. | For a quick lunch, I may want plain tuna and a clear ingredients panel rather than choosing by the front of the tin. Ingredients and nutrition come first for about 21% of consumers. |
| Pack-level assurance | Check fish-allergen information, any certification or catch-method statement, and the opened-tin storage instructions on the individual product. | If I am shopping for guests or choosing tuna by its sourcing statement, I need to know what this particular tin says before it goes in the cupboard. About 21% of consumers primarily look for that pack-level assurance. |
Buying mistakes to avoid
-
Confusing tin size with tuna quantity
The weight on the front can include packing liquid. Tesco Groceries lists 102g drained tuna in its 145g spring-water tin and 280g in its 400g can.
Use drained weight to work out how much tuna a meal will have, particularly when comparing single tins with a multipack or large can.
-
Treating every packing liquid alike
Spring water and sunflower oil are different recipe choices. The cited Princes sunflower-oil tuna lists 9.5g fat per 100g drained, while the cited Princes spring-water product lists 0.5g on that basis.
Choose the liquid for the dish, then read the exact product’s nutrition panel if fat, calories or salt affect your meal plan.
-
Opening a large tin without planning the remainder
A larger tin is less convenient if one meal uses only part of it. Marks & Spencer instructs shoppers to transfer unused tuna to a non-metallic container, refrigerate it and eat it within two days of opening.
If meals will be further apart, consider separate tins instead; follow the storage instructions on the pack you buy.
-
Applying a sourcing claim to an entire shelf
A retailer policy, an own-label statement and a claim on one tuna product do not necessarily describe every branded or own-label tin beside it.
Look for the certification or catch-method wording on the individual can when that information determines your choice.
Brands and retailers to consider
These examples help distinguish formats and product-level claims; check the particular tin rather than assuming a statement applies across a range.
John West
Its cited range includes brine chunks and a three-can no-drain spring-water format.
- Tesco Groceries describes the cited John West no-drain 3 x 100g product as MSC-certified.
- Check the exact variant for its ingredients, sourcing statement and directions; a claim on one pack does not establish those details for another.
Princes
Its cited chunk-tuna products offer spring-water and sunflower-oil choices in multipacks.
- Tesco Groceries lists four separate 102g drained portions for the cited spring-water multipack.
- The cited oil-packed product has a different nutrition profile; read its panel rather than treating the two liquids as interchangeable.
Tesco
Its cited own-label spring-water tuna comes in both 145g and 400g tins.
- Tesco Groceries lists drained weights of 102g and 280g respectively, making the difference between tin size and tuna quantity clear.
- The cited products state MSC certification and FAD-free fishing; check those statements on the pack selected.
Sainsbury's
Its cited own-label range includes spring-water and brine multipacks.
- In a 2023 statement, J Sainsbury plc described its own-label canned tuna as MSC-certified and pole-and-line caught.
- That statement concerns Sainsbury's own label, not every branded tuna product it sells.
Asda
Asda is a retailer to consider when checking tuna formats alongside its published seafood-sourcing policy.
- Asda says it aims to source wild-caught fish from MSC-certified fisheries or registered fishery-improvement projects.
- A retailer-wide aim does not confirm the certification or catch method of an individual tuna tin.
M&S
Its cited spring-water tuna is an option for shoppers checking a stated catch method on a particular product.
- Marks & Spencer describes its cited 160g spring-water chunks as pole-and-line caught.
- Check the chosen pack’s catch-method statement and storage directions rather than extending the description to other M&S tuna.

John West No Drain Tuna Chunks in Springwater, 3 x 100g
Consider this format if you want to open a separate spring-water portion for each meal. Check the pack’s nutrition basis and sourcing statement if either affects your choice; the stated 100g can size is not a drained-weight comparison.
No image available
Morrisons Fad Free Tuna Chunks in Spring Water, 6 x 145g
Six separate spring-water tins suit meals planned across different days. The 145g figure describes each can, so check drained weight for the tuna quantity; inspect the pack’s catch-method wording if that claim matters to you.
No image available
John West Tuna Chunks in Springwater, 4 x 125g
Four individual tins allow you to keep unopened portions for later sandwiches, salads or pasta. Check drained weight on this variant, and follow its own directions rather than assuming that wording for John West’s No Drain range applies.
No image available
Princes Tuna Chunks in Brine, 4 x 145g
Choose brine when it suits the intended dish rather than assuming it will work like spring water. The four tins can be opened separately; read the pack’s salt information and drained weight when planning portions.
No image available
Princes Tuna Chunks in Sunflower Oil, 4 x 145g
This four-tin format suits meals for which sunflower oil is part of the intended flavour and texture. Check the pack’s nutrition basis before comparing it with drained spring-water tuna, and use drained weight rather than the 145g can size to plan tuna portions.
Questions about tinned tuna
Should I use tin size or drained weight to plan Christmas meals?
Use drained weight to work out the amount of tuna available after the packing liquid is removed. Tesco Groceries lists 102g drained tuna for its cited 145g spring-water tin and 280g for its cited 400g can; check the figures on whichever products you choose.
What should I do with tuna left in an opened tin?
Follow the chosen pack’s instructions. Marks & Spencer directs shoppers buying its cited tuna to move unused contents to a non-metallic container, refrigerate them and eat them within two days of opening.
What should I check when buying tuna for a guest with a fish allergy?
Read the exact pack’s ingredients and allergen information before serving it. GOV.UK states that specified allergens in prepacked food must be clearly labelled in the ingredients list; fish is among those allergens.
Does a retailer’s sourcing statement cover every tuna tin it sells?
No. J Sainsbury plc’s 2023 MSC and pole-and-line statement concerns its own-label canned tuna, not every brand on its shelves. Check the individual tin for the certification or catch-method claim you want.
