Festival-goers packing individual bags
A labelled single bag makes its portion size and calories easier to check before it goes into your day bag.
Who is choosing these snacks?
Shoppers specifically looking for maize
A puffed texture does not identify the main ingredient. Check the ingredient list if maize, rather than simply a small savoury pack, is the requirement.
Groups sharing snacks around allergies
Keep each flavour’s packaging available so the person eating it can check its ingredients and allergen information.
What should you check?
Start with the calories and weight of the exact pack, then check its ingredients and allergen label. A multipack may contain a different bag size from the single-pack examples below.
| Priority | What to check | Your needs |
|---|---|---|
| Pack calories | Read the calories alongside the bag weight. Walkers UK lists Monster Munch Pickled Onion at 98 kcal per 20 g pack and Wotsits Cheese at 123 kcal per 22.5 g pack. | I want to know what one bag contributes, rather than compare packs as though they were the same size. |
| Maize ingredients | Check the first ingredient for the exact flavour. Walkers UK lists maize first for Monster Munch Pickled Onion and Wotsits Cheese, but potato starch first for Quavers Cheese. | If I’m looking for a maize snack, a small bag of another puffed snack does not meet that requirement. |
| Allergens | Read the current ingredients, highlighted allergens and any cross-contact statement on each flavour’s pack. Walkers UK lists milk and soya ingredients in Monster Munch Pickled Onion and milk in Wotsits Cheese. | When sharing snacks, I need each person to be able to check the bag they will eat. |
| Serving basis | Distinguish calories per pack, per serving and per 100 g. For a sharing bag, check the stated serving size and how much you intend to portion out. | A single bag is simpler to account for; with a sharing bag, I need to decide the portion rather than count the whole bag as one serving. |
Common buying mistakes
-
Calling a small bag a low-energy food
Calories in one small bag and calories per 100 g describe different things. Walkers UK lists 98 kcal per 20 g pack but 492 kcal per 100 g for Monster Munch Pickled Onion.
Use the per-pack figure for the portion you are packing. Do not treat an under-100-kcal bag as a claim about the food’s energy density.
-
Assuming every puffed snack is made from maize
Walkers UK lists potato starch first for Quavers Cheese. Its 16 g pack has 86 kcal, but that does not make it a maize-snack alternative.
Check the ingredient list before using pack calories to compare products for a maize-specific shortlist.
-
Assuming flavours share an allergen declaration
Seasonings can change the ingredients relevant to someone with an allergy. Walkers UK lists milk and soya ingredients for Monster Munch Pickled Onion and milk for Wotsits Cheese.
Keep individually labelled packs available when sharing and check the exact flavour’s current declaration.
Brand and retailer references
These references help distinguish product types and pack sizes; they are not a list of products available from any one retailer.
Monster Munch
Monster Munch Pickled Onion is a maize-based option with an individually stated pack size.
- Walkers UK lists 98 kcal per 20 g Pickled Onion pack and 492 kcal per 100 g.
- That flavour includes milk and soya ingredients; check the declaration for any other flavour separately.
Wotsits
Wotsits Cheese is a maize-based, cheese-flavoured snack that Walkers UK describes as baked, not fried.
- Walkers UK lists maize first in the ingredients for Wotsits Cheese.
- The stated 22.5 g pack has 123 kcal and contains milk; check other bag sizes on their own labels.
Quavers
Quavers Cheese offers a smaller stated pack, but it is not a match for a maize-specific search.
- Walkers UK lists 86 kcal per 16 g Cheese pack.
- Its ingredient list begins with potato starch, not maize; check its allergen label before sharing.
Tesco
Tesco is a retailer whose under-100-calorie snack category illustrates why individual bag sizes matter when looking at multipacks.
- Its category listing included Quavers Cheese 16 g bags and Wotsits Cheese 16.5 g bags in multipacks when reviewed in October 2026.
- A category listing does not establish that every product is maize-based or suitable for someone with an allergy.

Walkers Monster Munch Variety 12 x 20 g
The individual bags suit a festival group that wants separate portions. This variety pack contains twelve 20 g bags; check each flavour’s own calorie and allergen information rather than applying the Pickled Onion figures to the whole assortment.
No image available
Walkers Wotsits Really Cheesy 12 x 16.5 g
This multipack offers individual cheese-flavoured bags for taking to a festival. Its 16.5 g bags differ from the 22.5 g Wotsits Cheese pack discussed above, so use the calories on this pack’s label for a per-bag comparison and check its allergen declaration before sharing.

Propercorn Lightly Sea Salted 70 g
The 70 g bag is a sharing-size option rather than a set of individual portions. If pack calories matter, check its labelled serving size and portion out the amount you intend to eat; check the ingredients and allergen information on the bag too.

Walkers Wotsits Giants Really Cheesy 130 g
This 130 g sharing bag suits a group planning to divide a cheese-flavoured snack. Check its own serving and allergen information: the calories listed for a 22.5 g Wotsits Cheese bag do not describe a portion taken from this 130 g variant.

Nik Naks Nice Spicy Corn Snacks 6 x 20 g
Six individual 20 g bags provide a spicy corn-snack option for packing separately. Check this product’s per-bag calories if you have an under-100-kcal preference, and read the current allergen label before sharing.
Questions about festival snacks
Does a bag under 100 kcal mean the snack is low in energy?
No: a per-bag figure does not describe energy per 100 g. Walkers UK lists Monster Munch Pickled Onion at 98 kcal per 20 g pack and 492 kcal per 100 g. Use the first figure to compare the stated bags, without treating it as a claim about the food’s energy density.
Is Quavers Cheese a maize snack?
No for a maize-specific shortlist: Walkers UK lists potato starch first in the Quavers Cheese ingredients. Its 16 g pack has 86 kcal, but a smaller stated calorie figure does not change its ingredient base.
Can I assume maize snacks are suitable for someone avoiding milk or other allergens?
No. Walkers UK lists milk in Wotsits Cheese and milk and soya ingredients in Monster Munch Pickled Onion. Check the exact flavour’s current ingredients, allergen declaration and any cross-contact statement with the person who will eat it.
What should I check on a snack bought at a festival stall?
For a sealed, prepacked snack, read its own ingredients and allergen label rather than relying on the flavour name. For food that is not prepacked, ask the seller for its allergen information; the Food Standards Agency says food businesses must provide this information for both prepacked and non-prepacked food and drink.
