Who is buying for the trip?

The useful distinction is whether your passengers want to avoid sugar, avoid caffeine or simply have enough individual cans for the journey.

Travellers avoiding sugar

Compare the exact cola formulation, not just the brand. Coca-Cola Zero Sugar and Pepsi Max are listed with 0g sugars per 330ml, but neither standard formulation is caffeine free.

Travellers avoiding caffeine

Look for an explicit caffeine-free label. Sainsbury’s lists Diet Coke No Caffeine in a 24 x 330ml pack with no sugar or caffeine; a zero-sugar label alone does not establish caffeine content.

Groups choosing a case size

Count the people and the stops at which you expect to offer drinks. A 24-can case provides more individual cans than an 8-can pack, but it also takes up more space in the car.

What should you check before choosing?

Start with sugar and caffeine requirements, then match the number of 330ml cans to the trip rather than treating every multipack as interchangeable.

PriorityWhat to checkYour needs
Sugars per can Compare labels on the same 330ml basis. Asda Groceries lists 35g sugars for Coca-Cola Original Taste and 15g for Pepsi Cola per can; Tesco Groceries lists 0g for Coca-Cola Zero Sugar. “I’d like individual cans without sugar,” or “Our group prefers a sweetened cola and wants to know what each can contains.”
Caffeine Check the exact variant for caffeine or an explicit caffeine-free statement. Standard Pepsi Max and Coca-Cola Zero Sugar contain caffeine, according to Pepsi UK and Tesco Groceries; Sainsbury’s labels Diet Coke No Caffeine as caffeine free. “Caffeine matters to someone travelling with us, so I need more than a zero-sugar label.”
Can count Check both the number of cans and their volume. A 24 x 330ml case contains 7.92 litres; Tesco Classic Cola’s 8 x 330ml pack contains 2.64 litres. “There are only a few of us,” or “We’re sharing drinks across several stops.” Leave space in the car for the pack and empty cans.
Exact formulation Read the current ingredients and nutrition label when comparing original, zero-sugar and caffeine-free variants. A shared brand name does not make the variants equivalent. “I know which flavour the group wants, but I still need to check whether that particular pack matches our sugar or caffeine choice.”
Journey breaks Plan stops independently of the drinks you pack. THINK! advises a 15-minute break every 2 to 3 hours and says a sleepy driver should find a safe place to stop. “We’re driving a long way, so drinks can be part of the packing plan—not a replacement for rest.”

Mistakes to avoid

  • Assuming zero sugar means caffeine free

    Tesco Groceries lists caffeine flavouring in Coca-Cola Zero Sugar, while Pepsi UK lists caffeine in standard Pepsi Max. Either could be the wrong variant for a traveller avoiding caffeine.

    Choose a pack explicitly labelled caffeine free when that is the requirement, and check the exact variant on the can.

  • Choosing a sweetened case without checking each can

    Asda Groceries lists 35g sugars per 330ml can for Coca-Cola Original Taste and 15g for Pepsi Cola. Neither figure describes every cola sold under those brands.

    Compare the labels on a per-can basis before choosing the formulation and the number of cans.

  • Relying on cola when the driver feels sleepy

    A drink does not remove the need to stop and rest. THINK! advises drivers who feel sleepy to find somewhere safe to stop.

    Plan breaks before departure; if the driver becomes sleepy, stop safely rather than continuing because cola is available.

Brands and retailer references

Use these examples to distinguish specific formulations and pack sizes, not to assume that every product from a brand has the same ingredients.

Road-trip cola questions

Is zero-sugar cola automatically caffeine free?

No. Tesco Groceries lists caffeine flavouring in Coca-Cola Zero Sugar, and Pepsi UK lists caffeine in standard Pepsi Max. If a passenger avoids caffeine, choose a variant explicitly labelled caffeine free; Sainsbury’s labels Diet Coke No Caffeine as both sugar free and caffeine free.

How much drink is in a 24 x 330ml case?

It contains 24 individual cans and 7.92 litres in total. An 8 x 330ml pack, such as the listed Tesco Classic Cola, contains 2.64 litres; choose the count according to your group and the space available in the car.

Can a sleepy driver use cola instead of taking a break?

No. THINK! advises a driver who feels sleepy to find a safe place to stop and recommends planning a 15-minute break every 2 to 3 hours. Pack drinks for the journey, but plan rest stops separately.

Can this road-trip choice be used for school-provided drinks?

Do not use a road-trip selection as a school procurement decision. The Department for Education says the School Food Regulations 2014 set requirements for food and drink provided to pupils in state-funded schools in England. Its September 2026 guidance described updated standards planned for September 2027 as subject to Parliamentary approval; check the current rules for the relevant nation and school setting.

What should I read on the pack before buying?

Check the can count and volume, sugars per can, caffeine information and ingredients on the exact variant. Original, zero-sugar and caffeine-free colas are different formulations, even when they share a brand name.
