What matters when choosing?
Plan the dishes and the number of tins you will open, then choose between spring water, brine, sunflower oil and no-drain formats. The figures below describe consumers grouped by their main purchase concern, rather than every consideration they might have.
| Concern | What to check | Who this matters to |
| Usable quantity |
Compare the number of tins and the drained weight, not just the total weight including liquid. Match the tin count to the planned meals. |
If I am making several Easter meals, I need enough tuna without opening more tins than a dish requires. About 36% of consumers put usable quantity first. |
| Recipe and label fit |
Choose the packing liquid for the dish; read the exact variant's ingredients and nutrition panel when those details matter. |
A sandwich filling and an oil-dressed salad may call for different packing liquids. For about 29% of consumers, fitting the recipe and their label preferences is the primary need. |
| Preparation |
Check whether the tins are labelled no-drain and compare their size and opening style with conventional packs. |
When I am assembling buffet sandwiches or quick lunches, draining several tins adds a step. Reduced handling comes first for about 21% of consumers. |
| Pack assurance |
Read the fish allergen and storage information, and check any sourcing claim on the specific pack. |
Serving guests makes the current allergen details important, while a product-specific sourcing claim may also affect my choice. About 14% of consumers prioritise these label checks. |
Brands to consider
These brands provide examples of different tin sizes, packing liquids and label information. Compare the particular product, rather than assuming every range has the same format or instructions.
John West
Conventional chunks and no-drain tins offer different preparation choices.
- Sainsbury's lists John West sunflower-oil chunks in a 4 x 125g pack; Tesco lists a 3 x 100g no-drain pack.
- The smaller no-drain tins should not be treated as equivalent in quantity to conventional 145g tins. Opening and recyclability statements on retailer listings are product or brand claims, not findings about the whole range.
Princes
Its spring-water range includes several stated tin counts for a multi-meal shop.
- Princes lists 4 x 145g, 6 x 145g and 8 x 145g spring-water formats on its own product page.
- Check which format the chosen retailer carries. Sourcing statements on individual listings should be checked against the exact product.
Tesco
Its own-label range includes multipacks and larger individual tins.
- Tesco lists own-label 4 x 145g chunks in brine and spring water, as well as 400g tins.
- A larger individual tin and a pack of separately sealed tins serve different meal plans; check the drained quantity and storage directions for the one selected.
Sainsbury's
Own-label 4 x 145g chunks are listed in spring water, brine and sunflower oil.
- The spring-water listing identifies skipjack tuna and spring water in its ingredients.
- That listing directs shoppers to transfer leftovers to a non-metallic container, refrigerate them and use them within one day. Follow the directions for the variant actually bought.
Asda
Own-label four-packs allow a choice of packing liquid in the same stated 4 x 145g format.
- Asda lists tuna chunks in spring water, brine and sunflower oil.
- The listed energy and fat values differ between its spring-water and sunflower-oil products. Read the panel for the chosen pack rather than transferring figures between variants.
M&S
Individual tins are an option when the specific product and its sourcing statement matter more than a multipack format.
- M&S lists a 160g spring-water chunks tin and describes it as pole-and-line caught under its Forever Fish policy.
- The cited 160g tin is an individual product, not a bulk multipack; the sourcing statement is M&S's product claim.

John West Tuna Chunks in Springwater, 4 x 125g

Questions about buying and storing tuna
How many tins should I buy for several Easter meals?
Start with the number of dishes you plan to make and how many separate tins each will use. Tesco, Asda, Sainsbury's and Princes list 4 x 145g formats; Princes also lists 6 x 145g and 8 x 145g spring-water formats. Check the drained weight and the selected pack's tin count before choosing a larger format.
Should I choose spring water, brine or sunflower oil?
Choose the packing liquid that fits the dish, then check the exact product's ingredients and nutrition panel. Asda's listings show that even its spring-water and sunflower-oil four-packs differ in listed energy and fat values, so figures for one variant should not be applied to another.
Can leftover tuna stay in an opened tin?
Follow the directions on the tin you opened. Sainsbury's instructs shoppers to transfer leftovers from its cited spring-water four-pack to a non-metallic container, refrigerate them and use them within one day; the cited Morrisons brine tin allows two days after transfer and refrigeration.
What should I check before serving tuna to guests?
Ask guests about fish allergy and read the current pack's ingredients and allergen information before serving. Fish appears in the ingredients of the cited tuna products; use the label on the product in hand for the meal you are preparing.
Does pregnancy affect how much tuna to plan for?
Yes. NHS guidance for pregnancy says not to eat more than four cans of tuna or two tuna steaks a week because tuna can contain mercury. Take that weekly intake guidance into account when planning portions; buying a multipack does not mean eating it all in one week.
