Students set on a glass bottle
If the bottle format is part of the lunch choice, compare the serving you will carry: Tesco lists Coca-Cola Original Taste in 250ml glass bottles and Pepsi Max in 330ml glass bottles.
Who is choosing?
Students checking sugar per bottle
Tesco lists 27g sugars in a 250ml Coca-Cola Original Taste glass bottle and 0g in a 330ml Pepsi Max glass bottle. Compare the bottle figures, not just the pack sizes.
Students avoiding caffeine
If caffeine-free is essential for your afternoon plans, check the exact product label rather than assuming a zero-sugar cola meets that requirement. Pepsi UK describes Pepsi Max Caffeine Free as having zero caffeine, but the container format needs checking separately.
What should you check?
Decide whether glass packaging, sugar content or a caffeine-free label is the condition you will not compromise on; then check the bottle and pack details.
Original cola in glass
Consider it: Coca-Cola Original Taste suits a 250ml glass-bottle lunch serving if you want that formulation.
Trade-off: Tesco lists 27g sugars per bottle, and Coca-Cola GB lists caffeine flavouring.
Zero-sugar cola in glass
Consider it: Tesco lists Pepsi Max glass bottles with 0g sugars per 330ml bottle.
Trade-off: This is a six-bottle pack; Pepsi UK lists caffeine flavouring and sweeteners in Pepsi Max.
Caffeine-free cola in another container
Consider it: If avoiding caffeine takes precedence over glass, look for an explicit caffeine-free declaration, as on Pepsi Max Caffeine Free.
Trade-off: Check the particular product’s container and pack size rather than assuming it comes in glass.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar per bottle | Compare sugars for the whole bottle and note its volume. Tesco lists 27g per 250ml Coca-Cola Original Taste glass bottle and 0g per 330ml Pepsi Max glass bottle. | I want to know how much sugar is in the drink I will have with lunch, rather than comparing figures for different serving sizes. |
| Caffeine and ingredients | Check for an explicit caffeine-free declaration; zero sugar alone does not establish it. Read the sweetener and phenylalanine information if relevant to you. | If I need to avoid caffeine before an afternoon lecture, I would choose by the exact product label, even if that means giving up the glass bottle. |
| Bottle and pack size | Check both volume and pack count: Tesco lists Coca-Cola Original Taste as 4 × 250ml and Pepsi Max as 6 × 330ml glass bottles. Check current availability before planning a lunch around either pack. | A smaller bottle might fit my lunch break, but I also need somewhere to keep the rest of a multipack. |
| Taking glass to campus | Check your building’s rules on glass containers and plan how to protect and dispose of the bottle. Use the recycling instructions available at your university or locally. | If I am carrying lunch between lectures, the bottle needs to fit safely in my bag and be permitted where I am going. |
Common buying mistakes
-
Judging sugar by bottle size alone
Tesco lists 27g sugars in its 250ml Coca-Cola Original Taste glass bottle. For context, the NHS advises adults to have no more than 30g of free sugars a day.
Read the sugars figure for the bottle you intend to drink; if you are choosing a no-sugar cola, check that declaration on the specific product.
-
Assuming zero sugar means no caffeine
Pepsi UK lists caffeine flavouring in Pepsi Max. Pepsi Max Caffeine Free is a separate product described by Pepsi UK as having zero caffeine.
Check the full variant name and caffeine information, especially when container format is a secondary concern.
-
Planning on a multipack without checking stock
Tesco lists the glass-bottle choices in packs of four or six, rather than as a single bottle in those listings. Stock can also change before your next campus day.
Check the current pack count and local delivery or collection availability, then consider where you will store the remaining bottles.

How much sugar is in a 250ml Coca-Cola Original Taste glass bottle?
Tesco lists 27g sugars per 250ml bottle. Compare the per-bottle figure when choosing a lunch drink; the NHS advises adults to have no more than 30g of free sugars a day.
Which of these glass-bottle colas lists no sugar?
Tesco lists 0g sugars per 330ml Pepsi Max glass bottle in its six-bottle pack. Check current local stock before relying on that pack for a lecture-day lunch.
