For one person’s road-trip snack stop, start with a 150ml can if you want a small portion without opening a larger bottle; Tesco Groceries lists 150ml Fever-Tree and Schweppes multipacks. A 200ml Fentimans bottle offers a fuller portion, while Britvic describes its 330ml tonic can as two serves, making it a different choice for sharing or drinking after arrival. If you will drive, keep the drink alcohol-free rather than trying to calculate a safe number of alcoholic drinks.
An unmixed tonic or other alcohol-free mixer can go in the snack bag for the person driving. GOV.UK cautions that the number of alcoholic drinks corresponding to the legal driving limit varies from person to person, so a drink count is not a driving plan.
A 150ml can suits someone who wants to open one mixer at a stop rather than carry a larger opened bottle. Tesco Groceries lists Fever-Tree and Schweppes multipacks in this size.
Fentimans documents a 200ml bottle range for a larger individual portion. For sharing or making two serves, Britvic describes its 330ml Indian Tonic Water can as providing two serves.
Choose the portion you expect to use first, then check the exact drink’s label and whether it is for the driver or for later mixing.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare the volume of each can or bottle with the number of people drinking. Tesco Groceries lists 150ml multipacks; Fentimans documents 200ml bottles; Britvic calls its 330ml can two serves. | I want to finish one small mixer at a snack stop, or choose a fuller bottle for later. If we will share, a two-serve can may make more sense than separate mini cans. |
| Ingredients | Read the ingredients and nutrition information on the exact variant. Check sugars and sweeteners separately: Sainsbury’s lists aspartame and a source of phenylalanine for its Schweppes Slimline 1L tonic, which does not establish the recipe of every pack size. | I may prefer a particular tonic recipe or avoid a specific sweetener, so the name ‘light’ or ‘slimline’ is not enough on its own. |
| Drink style | Decide whether the mixer is for drinking on its own or combining with something after arrival. Fentimans lists 200ml tonic, soda, ginger ale, ginger beer, rose lemonade and flavoured tonic options. | For a snack stop, I want something I would drink as it is. If the drink is for later, I can choose the mixer style to suit that plan. |
| Driver’s drink | Keep any drink intended for the driver free of added alcohol. GOV.UK says alcoholic drinks cannot be converted into one reliable count for the legal driving limit; limits also differ between Scotland and the rest of the UK. | If I am driving, I want an alcohol-free drink rather than an alcoholic mix or a calculation about when I can drive. |
Britvic describes its 330ml Indian Tonic Water can as two serves. That is a different portion plan from opening one 150ml can for one person.
For an individual stop, compare 150ml cans and 200ml bottles first; choose 330ml when you plan to share it or use two serves.
Sainsbury’s lists aspartame and a source of phenylalanine for its Schweppes Slimline 1L tonic. A no-sugar description does not tell you whether its ingredients suit your preferences.
Read the ingredients and nutrition panel on the exact size and variant you intend to pack.
GOV.UK says there is no fixed number of alcoholic drinks that equals the legal limit for everyone, and the limit differs between Scotland and the rest of the UK.
Pack an alcohol-free drink for anyone who will drive, and leave alcoholic mixed drinks until driving has finished.

Yes, tonic water consumed without added alcohol is a soft drink. Keep a mixer intended for the driver alcohol-free; Sainsbury’s describes its Schweppes Slimline tonic as a soft drink that can be drunk on its own.
No fixed drink count works for everyone. GOV.UK says the number of drinks corresponding to the legal limit varies by person, and the limit in Scotland differs from the rest of the UK. Choose an alcohol-free drink if you will drive.
Choose a 150ml can when you want to open one small portion at a road-trip stop without managing a larger opened bottle. Tesco Groceries lists Fever-Tree and Schweppes multipacks in that size; a larger bottle makes more sense if several people will use it.
Choose by the exact product label, particularly if sugars or sweeteners affect your choice. Sainsbury’s describes its Schweppes Slimline 1L tonic as no sugar and lists aspartame, but check the label of the particular can or bottle you are buying rather than assuming every format has the same recipe.
Keep cans or bottles protected in the bag and open them when you are ready to drink. Sainsbury’s says its Schweppes Slimline tonic is best served chilled, so check the directions on your chosen product if you plan to pack it in a cooler.
