Who is this for?

Rushed weekday breakfast planners

If you make toast, wraps or sandwiches before work, the choice is whether avoiding the draining step matters more than the format and usable quantity of a standard tin.

Regular tuna buyers

If tuna appears in several breakfasts, compare the drained quantity in each tin and how many tins you will use, rather than relying on the pack’s net weight.

Sourcing-conscious shoppers

If certified sourcing matters to you, check the ecolabel on the individual tin alongside its drained weight, nutrition panel and format.

What should you compare?

Spring-water chunks

Choose when: You can drain a tin before making toast, a wrap or a breakfast sandwich.

Trade-off: Draining adds a step, and chunks give a different presentation from larger steak pieces.

No-drain tuna

Choose when: You need to assemble breakfast quickly and want to avoid dealing with packing liquid.

Trade-off: The no-drain description does not establish how its usable quantity or nutrition compares with another tin.

Tuna steaks

Choose when: Larger pieces matter for an open sandwich or another breakfast where the tuna remains visible.

Trade-off: Check drained weight separately from net weight; the cited M&S tin contains 200g net and 150g drained.

Priority What to check Your needs
Usable quantity Compare drained weight with net weight. For multipacks, check the drained quantity per tin as well as the number of tins. I make tuna breakfasts regularly and want to know how much tuna each tin will provide.
Nutrition Use the same basis when comparing labels. Sainsbury's lists 26.1g protein and 0.70g salt per 100g drained for its spring-water chunks; Princes lists 23.5g protein per 100g drained for its spring-water chunks. For tuna on toast or in a wrap, I want to compare the protein and salt stated on the exact products I am considering.
Preparation Check whether the tin is standard, no-drain or drained-ready. Confirm what needs doing before adding it to a sandwich. If breakfast must be assembled quickly, avoiding a draining step is useful to me.
Sourcing Look for an MSC ecolabel on the particular product; do not assume it applies to every tin in a range. Check drained weight and nutrition separately. I want certified sourcing to be part of my choice without using the label as a substitute for the rest of the product information.
Texture Distinguish chunks from steak-style pieces. For steak tins, compare net and drained weights rather than assuming the full tin weight is tuna. For an open sandwich, larger pieces may matter more to me than they do for a mixed filling.
Opening and storage Check the fish-allergen declaration and the exact tin’s leftover instructions. The cited Sainsbury's and M&S products specify different refrigerated-use periods after opening. If I will not use a whole tin at breakfast, I need to follow its instructions for transferring and storing the remainder.

Common buying mistakes

  • Reading net tin weight as usable tuna

    Packing liquid can account for part of the stated weight: the M&S tuna steak example is 200g net and 150g drained.

    Check drained weight on the tin before comparing the quantity you can use for breakfast.

  • Assuming no-drain means more tuna

    A no-drain format removes a preparation step, but that feature alone does not establish its usable quantity or nutrition relative to standard chunks.

    Choose it when avoiding draining matters, and compare the individual product labels for everything else.

  • Assuming all spring-water chunks have the same nutrition

    Sainsbury's lists 26.1g protein per 100g drained for its cited own-label chunks; Princes lists 23.5g per 100g drained for its cited chunks.

    Read the nutrition panel on the exact tin, including the basis used for its figures.

  • Using one leftover-storage rule for every tin

    The cited Sainsbury's product says to refrigerate transferred leftovers and use them within one day; the cited M&S product specifies two days.

    Transfer leftovers to a non-metallic container, refrigerate them and follow the time stated on your tin.

Brand and retailer references

These ranges illustrate formats to compare; the details of the individual tin matter more than the brand name alone.

Tesco

Tesco Groceries lists own-label spring-water chunks in single tins, larger tins and multipacks.

  • Its listing includes 145g, 400g and 4 × 145g formats.
  • Check the drained quantity for the format you choose; pack size alone does not give the usable tuna weight.

Sainsbury's

Its cited own-label product is skipjack tuna chunks in spring water.

  • The product information states 26.1g protein and 0.70g salt per 100g drained.
  • Its instructions say to refrigerate transferred leftovers and use them within one day; follow the label on the tin you buy.

Princes

Princes describes standard spring-water chunks and a separate drained, ready-to-use range.

  • Its spring-water chunks list tuna and spring water as ingredients, with 23.5g protein per 100g drained.
  • Check the specific format and nutrition panel rather than applying the standard-chunk figures to another Princes product.

John West

John West products listed by retailers include standard spring-water chunks and a separate no-drain format.

  • The cited listings identify 4 × 125g standard chunks and 3 × 100g no-drain chunks.
  • Do not assume a standard-chunk multipack has the no-drain feature; check the exact product name.

M&S

The cited M&S tuna steak in spring water offers a larger-piece format.

  • Its product information states 200g net, 150g drained and 25.3g protein per 100g drained.
  • The listing warns that bones may be present and says to refrigerate transferred leftovers and eat them within two days.

Frequently asked questions

How can I compare the usable tuna in different packs?

Check drained weight, not just the net weight printed on the front of the tin. For multipacks, compare the drained quantity per tin and the number of tins; then consider whether a no-drain format saves a preparation step you care about.

Does spring-water tuna always have fewer calories than tuna in oil?

Check the exact products rather than relying on their packing liquids alone. Sainsbury's lists 180kcal and 9.5g fat per 100g drained for its cited Princes sunflower-oil chunks; use the same per-100g-drained basis when reading a spring-water tin’s nutrition panel.

How should I store tuna left over after breakfast?

Transfer leftovers to a non-metallic container and refrigerate them, following the time on your tin. The cited Sainsbury's product says to use them within one day, while the cited M&S product says within two days.

Which allergen should I check on tinned tuna?

Check for fish. The cited Princes product information and Joybuy product page both identify fish as an allergen; read the label of the exact product before use if this affects your choice.

Does an MSC label settle which tin to choose?

No. An MSC ecolabel identifies a sourcing criterion, not the tin’s drained quantity, nutrition or texture. Check that the individual product carries the label, then compare those other details separately.
