Choose the flavour your guests will drink, then check sugar, caffeine and sweeteners before deciding whether one bottle suits the table. Regular cola serves a different preference from zero-sugar cola or citrus fizz; if guests have mixed preferences, two different drinks may be more useful than more of the same one. Coca-Cola Original Taste labels a 2-litre bottle as eight 250ml glasses, so plan quantities around likely pours rather than bottle count alone.
If guests prefer different flavours, consider whether a cola and an orange or lemon-lime drink would be more useful than two bottles of one flavour. ASDA Groceries and Tesco Groceries label Coca-Cola Original Taste 2L as eight 250ml glasses; larger pours mean fewer glasses.
Regular cola and drinks labelled zero sugar are distinct options. Check the nutrition information per 100ml or per serving, and read the ingredients if sweeteners matter to anyone at the table.
A zero-sugar label does not establish that a drink is caffeine free. Check the exact bottle when serving guests who avoid caffeine; Fanta Orange Zero and Tesco Caffeine Free Diet Cola are described as caffeine-free options in their product information.
Start with the flavours and number of guests, then compare the labels of drinks that could suit the table.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour | Choose between cola, orange and lemon-lime. Check whether guests want more than one flavour. | Not everyone at my brunch wants cola, so I may prefer two different drinks to two of the same. |
| Sugars | Compare sugars per 100ml and per serving. Tesco Groceries lists 27g sugars per 250ml for Coca-Cola Original Taste; ASDA Groceries lists 0.4g per 100ml for Fanta Orange Zero. | I want guests to be able to distinguish regular cola from drinks with little or no sugar, without assuming their labels mean identical ingredients. |
| Caffeine and sweeteners | Read the caffeine statement and ingredients on each bottle. Pepsi UK lists caffeine-containing flavourings and a source-of-phenylalanine notice for Pepsi Max. | If someone avoids caffeine or needs to check a sweetener warning, the exact drink matters more than whether it is called a diet or zero-sugar option. |
| Quantity | Use the labelled serving size to estimate glasses. Check both bottle size and how many bottles are in a multipack. | For a small gathering, I want enough to share without buying a multipack that exceeds what we are likely to open. |
| Leftovers | Check storage directions and the period for using an opened bottle. Tesco Groceries says to consume its Caffeine Free Diet Cola within 3 days of opening. | If only a few guests will have fizzy drinks, I need to consider whether we will use an opened 2-litre bottle promptly. |
ASDA Groceries and Tesco Groceries show a 2-litre Coca-Cola Original Taste bottle as eight 250ml glasses. Larger pours reduce that number, and one flavour may not suit everyone.
Estimate who is likely to drink it and how much they will pour. For mixed preferences, consider splitting the quantity across flavours.
Pepsi Max and Dr Pepper Zero list caffeine-containing flavourings, despite being zero-sugar drinks.
Check the caffeine statement on the exact bottle before selecting a drink for someone avoiding caffeine.
Tesco Groceries lists 27g sugars in a 250ml glass of Coca-Cola Original Taste. The NHS advises that children avoid sugary fizzy drinks.
Have water and milk available for children rather than relying on fizzy drinks as their main refreshments.
Tesco Groceries instructs buyers to consume its Caffeine Free Diet Cola within 3 days of opening.
Open bottles as needed and follow each drink’s storage instructions.
An opened bottle left unused beyond its stated period may be wasted.
These examples illustrate different drink styles; the details apply to the named products, not every drink made by each brand.
Coca-Cola Original Taste 2L is a regular cola option for guests who specifically want that flavour.
Pepsi Max is a zero-sugar cola option, distinct from Pepsi Regular.
Sprite Zero Sugar 2L offers a lemon-lime flavour instead of cola.
Fanta Orange Zero 2L is an orange-flavoured option described as caffeine free.
Dr Pepper Zero 2L offers another zero-sugar flavour for guests who prefer it to standard cola.
Tesco Caffeine Free Diet Cola 2L is an own-label cola-flavoured option labelled caffeine free and no added sugar.
These Joybuy options are multipacks of 2-litre cola bottles: one regular and two labelled without sugar. Check how many bottles your brunch needs, and confirm caffeine information on the exact pack when that affects your choice.

A regular cola option for guests who want a sugar-containing drink. This pack has eight 2-litre bottles; it contains caffeine-containing flavourings, so check whether the quantity and drink suit your group.
No image available
A cola option for guests who want a drink listing 0g sugars. The six-bottle pack contains caffeine and sweeteners including aspartame, and carries a source-of-phenylalanine notice; check whether six bottles suit the occasion.
No image available
A six-bottle cola multipack listing 0g sugars. Check the current bottle label before choosing it for someone avoiding caffeine: the product information’s caffeine-free description conflicts with a caution referring to caffeine. It lists aspartame and a source of phenylalanine.
Allow eight 250ml glasses as a starting point: ASDA Groceries and Tesco Groceries give that serving guide for Coca-Cola Original Taste 2L. You will get fewer glasses if guests pour more than 250ml each.
Not necessarily. Pepsi Max and Dr Pepper Zero list caffeine-containing flavourings, while Tesco Caffeine Free Diet Cola is explicitly labelled caffeine free. Read the exact bottle’s ingredients and caffeine statement when choosing for someone who avoids caffeine.
Have water and milk available rather than making fizzy drinks the main option. The NHS advises that children avoid sugary fizzy drinks; a zero-sugar label alone does not establish that a drink is suitable for every child.
Check each bottle’s storage and use-after-opening directions before opening it. Tesco Groceries says its Caffeine Free Diet Cola should be consumed within 3 days of opening, so opening bottles only as needed may leave more unopened for later.
