Late-night snackers watching portion size
If you plan to have a small treat, a serving stated per biscuit or by weight makes it easier to work out how much you intend to eat.
Who this helps
The useful comparison changes depending on whether portion size, nutrition information or ingredients are your main concern.
Shoppers comparing sugars and saturates
Similar-looking chocolate biscuits can have different labelled values. Compare sugars and saturated fat for the portion you would actually have, rather than judging by shape or coating alone.
Shoppers checking allergens
Check the current pack for milk, wheat or gluten, soya and any precautionary nut statement relevant to you. Sainsbury's advises checking packaging because ingredients can change.
What to compare
Start with the labelled serving, then compare its nutrition values and ingredients. A per-biscuit figure and a 25 g serving are not necessarily equivalent.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check whether the serving means one biscuit or a stated weight, and how many biscuits you intend to eat. Tesco Groceries lists one digestive as 17 g and one covered bourbon as 27 g; its Mikado listing gives values per 25 g. | I want a portion I can identify before opening the pack, rather than assuming that one biscuit or one handful is the same across products. |
| Sugars and saturates | Compare both values on the same labelled basis and note the serving weight. Tesco Groceries lists 5.4 g sugars and 2.0 g saturates per 17 g digestive, 8.6 g and 2.7 g per 25 g Mikado serving, and 12.6 g and 4.0 g per 27 g covered bourbon. | If sugars or saturated fat matter to my choice, I need the values for the amount I would eat, not a judgement based on the biscuit's appearance. |
| Ingredients and allergens | Read the current pack's ingredients, emphasised allergens and precautionary statements. The Tesco Groceries examples list milk and wheat; its Mikado listing also states that it may contain nuts. | I need to check the particular pack against my dietary requirements, especially if I have bought the product before and its ingredients may have changed. |
Common buying mistakes
-
Treating every serving figure as one biscuit
Tesco Groceries gives per-biscuit values for its digestive and covered bourbon, but a per-25 g serving for Mikado. Comparing the figures without their weights can obscure how much biscuit each represents.
Read the serving definition first, then compare the values with the amount you expect to eat.
-
Choosing by coating or shape alone
The three Tesco Groceries examples have different sugars and saturates on their stated portions. A familiar biscuit format does not tell you those values.
Check the exact product's serving weight and nutrition label, including any traffic-light information shown on its pack.
-
Relying on an older ingredient list
An earlier pack or online listing may not reflect the ingredients of the pack you are about to eat. Sainsbury's advises shoppers to check packaging because products and ingredients can change.
Read the current pack's allergen declaration and any precautionary statement before purchase or consumption.
Brand references
These examples show biscuit formats to compare; a brand name alone does not establish the nutrition or ingredients of a particular pack.
McVitie's
Tesco Groceries lists McVitie's chocolate digestive and Mint Club Digestives products in its chocolate-biscuit category.
- Digestive and Club-style formats offer different biscuit types to consider.
- Check the exact pack before comparing portions, sugars, saturates or allergens; a category listing does not establish those values across the range.
Fox's
Tesco Groceries lists Fox's chocolate biscuit formats including Chocolate Viennese and Milk Chocolate Rounds.
- The listed formats give shoppers different biscuit styles to compare.
- Use the chosen pack's label for serving size, ingredients and nutrition rather than assuming the formats are alike.
Tesco
Tesco Groceries provides product information for its half-coated milk chocolate digestive and milk chocolate-covered bourbon.
- Their stated per-biscuit weights and nutrition values allow a comparison with the serving sizes kept in view.
- The digestive is listed per 17 g biscuit and the covered bourbon per 27 g biscuit. Check the current pack before relying on an online label.

Gullon Zero Dark Chocolate Ginger Oaties 285g
The dark chocolate and ginger flavour distinguishes this oat biscuit from the other options here. If a particular sugar or saturated-fat value matters to you, compare the current pack's figures for your intended portion.
Questions about choosing and storing biscuits
What should I check if I have a milk, wheat, soya or nut allergy?
Read the allergen information on the current physical pack before eating. The Tesco Groceries chocolate-biscuit examples list milk and wheat, while its Mikado listing also includes soya and a may-contain-nuts statement. Sainsbury's notes that ingredients can change.
How should I store chocolate biscuits after opening them?
Follow the instructions on the particular pack. Check whether it calls for cool, dry storage or an airtight container after opening, and keep chocolate-coated biscuits away from heat where the pack directs you to do so.
What if I expect to have chocolate biscuits regularly?
Compare the labelled portion, sugars and saturated fat for the amount you expect to eat. NHS packaged-snack guidance recommends checking traffic-light labels, so use any colours shown alongside the serving details rather than judging a biscuit by its name or size.
