Hosts serving a drink after dinner
A smaller glass may suit the occasion better than a whole bottle. Check the stated serving size, especially when a bottle contains more than one portion or a syrup needs mixing.
Who is this choice for?
Shoppers comparing sugar labels
If you want a no-added-sugar option, compare that claim with total sugars on the nutrition label. Milk can contribute sugars to the total, and some products contain sweeteners.
People buying for guests with dietary requirements
A vegan syrup, a lactose-free milkshake and a finished drink without milk are different choices. Check the exact product and every ingredient used to prepare it.
What should you check?
Decide how much you plan to serve, then compare labels for sugar, ingredients and dietary suitability on that same serving basis.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar labelling | Read both the no-added-sugar claim and total sugars per intended serving. Check the ingredients if you wish to avoid sweeteners. The NHS explains that naturally occurring milk sugars appear in the total-sugars figure. | I want to distinguish no added sugar from no sugar when choosing a drink for after dinner. |
| Serving size | Check portions per bottle and compare energy and sugars for the amount you will pour. ASDA Groceries lists two 200ml portions in a 400ml Mars bottle; its Crusha example makes 200ml from 30ml syrup and 170ml semi-skimmed milk. | A whole bottle may be more than I intend to serve, or I may prefer to mix a smaller glass. |
| Milk and allergens | Read the current allergen declaration for the exact drink. Check the chosen base as well as a vegan syrup; a lactose-free claim does not establish that a shake contains no milk. | For a guest avoiding milk, I need to know what is in the finished drink, not just what is in the syrup. |
| Drink format | Choose between a ready-to-drink serving and a syrup or powder that needs preparation. For mixes, check the directions and which milk or plant-based drink their stated nutrition uses. | I may want a bottle that needs no mixing, or the flexibility to choose the base and amount served. |
Common buying mistakes
-
Reading ‘no added sugar’ as ‘no sugar’
Milk sugars can still appear in the total. ASDA Groceries lists 24.3g total sugars for a whole 400ml Galaxy no-added-sugar milkshake.
Compare total sugars for the amount you intend to drink, as well as the front-of-pack claim.
-
Checking a vegan syrup but not the prepared shake
Mixing a vegan syrup with cow’s milk makes a milk-containing drink. ASDA Groceries calculates its Crusha chocolate example using semi-skimmed milk, so those prepared-drink figures do not describe a version made with a plant-based drink.
Check the syrup and your chosen base, including their ingredients and allergen information.
-
Treating lactose-free as milk-free
Lactose avoidance and milk-allergen avoidance are different requirements. The Food Standards Agency identifies milk as an allergen ingredient.
If a guest must avoid milk, check the current milk-allergen declaration rather than choosing from a lactose-free claim alone.
-
Comparing a bottle with a prepared glass
Serving definitions differ: ASDA Groceries lists two 200ml portions for its 400ml Mars drink, while its Crusha example describes one 200ml prepared shake.
Compare nutrition for the amount you would actually serve, rather than treating both packs as one serving.
Brand and retailer references
These examples show why the exact variant, pack size and preparation method matter; a brand name alone does not establish a drink’s ingredients or nutrition.
Yazoo
Tesco Groceries lists Yazoo no-added-sugar 200ml cartons alongside a standard 1-litre chocolate milkshake.
- Yazoo says its 200ml children’s cartons have no added sugar or artificial sweeteners; their sweetness comes from sugars in milk.
- Check the exact variant: the carton claim does not apply to every Yazoo drink.
Müller Frijj
Tesco Groceries lists 330ml Müller Frijj milkshakes, including chocolate and strawberry flavours.
- An individual bottle gives you a defined pack size to compare with other formats.
- Check the exact bottle’s nutrition and ingredients if a no-added-sugar option matters to you.
Mars
ASDA Groceries lists a 400ml Mars chocolate milkshake labelled no added sugar.
- Its label defines two 200ml portions and lists 13g total sugars per portion.
- It contains milk and barley; check suitability for the person drinking it.
Tesco
Tesco Groceries lists ready-to-drink milkshakes and an own-label no-added-sugar strawberry milkshake powder.
- The powder is described as containing a sweetener and added vitamins and as suitable for vegetarians.
- Tesco advises reading the current pack label because ingredients, nutrition and allergen information can change.
Sainsbury’s
Sainsbury’s lists a no-added-sugar Crusha strawberry syrup and a lactose-free Barebells Cookies & Cream ready-to-drink shake.
- The Crusha syrup is labelled suitable for vegans; the Barebells drink is labelled lactose free and lists 24g protein per serving.
- A syrup’s suitability does not establish the suitability of the finished drink. Lactose-free does not mean milk-free.
Asda
ASDA Groceries lists no-added-sugar ready-to-drink milkshakes and a Crusha chocolate syrup.
- Its Galaxy bottle lists nutrition for both 100ml and 400ml; its Crusha listing gives figures for a specified prepared shake.
- Compare those figures on the amount you plan to serve: a whole bottle and a prepared glass are different quantities.

Applied Nutrition Protein Nutrition Shake Strawberries & Cream Flavour, 8 x 330ml
A ready-to-drink bottle avoids mixing for an after-dinner serving. The stated 330ml bottle serving lists 198 kcal and 11.6g total sugars; check whether that is the amount you want to serve. It contains milk, and the product guidance calls for healthcare-professional advice before use for under-18s, pregnant or breastfeeding people, and those with relevant medical conditions or medication.

Applied Nutrition Protein Nutrition Shake Double Chocolate Flavour, 8 x 500ml
This ready-to-drink option has a larger stated bottle serving to consider after dinner. One 500ml bottle lists 240 kcal and 17g total sugars; compare those figures with the amount you intend to pour. It contains milk, and the product guidance calls for healthcare-professional advice before use for under-18s, pregnant or breastfeeding people, and those with relevant medical conditions or medication.
Questions about milkshakes
Does ‘no added sugar’ mean a milkshake is sugar-free?
No. A milk-based shake can contain naturally occurring milk sugars. ASDA Groceries lists 6.1g total sugars per 100ml and 24.3g per 400ml bottle for its Galaxy no-added-sugar shake, so check both total sugars and your intended serving.
Can a vegan syrup make a vegan Christmas drink?
Yes, if you mix a vegan syrup with a suitable plant-based drink and check the finished ingredients. ASDA Groceries labels its Crusha chocolate syrup suitable for vegans, but its prepared-drink nutrition uses semi-skimmed milk.
Does lactose-free mean suitable for someone avoiding milk?
No. A lactose-free claim does not establish that a milkshake is free from milk, which the Food Standards Agency identifies as an allergen ingredient. Check the current allergen declaration for the exact product if a guest must avoid milk.
How do I choose a smaller after-dinner serving?
Check how many portions the bottle lists, pour the amount you intend to serve, or prepare a smaller glass from a mix. Compare energy and total sugars for that amount rather than comparing a whole bottle with one prepared glass.
Should I check the pack label again when buying?
Yes. Tesco Groceries advises that food products can be reformulated, changing ingredients, nutrition and allergen information. Use the current pack label to check the exact variant you plan to serve.
