For an occasional fizzy drink alongside a pre-workout snack, choose a zero-sugar glass-bottle cola if you want cola without sugar and are comfortable with sweeteners and caffeine flavouring. If avoiding caffeine matters more, Fanta Orange is described by its maker as caffeine free, but contains 4.5g sugars per 100ml. Original Coca-Cola and regular Pepsi are preference-led choices rather than low-sugar options: the listed 330ml servings contain 35g and 36g sugars respectively.
Who might consider these drinks?
People choosing a drink alongside a pre-workout snack
If you want a fizzy drink in glass for an occasional serving, decide separately what you want from your food snack and what you want to drink. Check the drink’s sugar content and ingredients rather than treating its packaging as a reason to choose it before exercise.
Cola drinkers watching sugar
For cola in glass without sugar, the listed Coca-Cola Zero Sugar and Pepsi MAX 330ml bottles each contain 0g sugars. Both ingredient lists include sweeteners and caffeine flavouring, so check whether those ingredients suit your preferences.
People avoiding caffeine
Fanta describes its Orange glass-bottle drink as caffeine free. It contains 4.5g sugars per 100ml, so caffeine avoidance and sugar content are separate decisions.
What should you check before choosing?
Start with the bottle’s nutrition panel and ingredients, then confirm that the pack is glass and available from the retailer you plan to use.
| Priority | What to check | Your needs |
| Sugar per bottle |
Compare the bottle size with sugars per 100ml or per serving. Tesco lists 35g sugars for a 330ml Coca-Cola Original serving; Regency Foods lists 36g for a 330ml regular Pepsi glass bottle. The listed Coca-Cola Zero Sugar and Pepsi MAX glass bottles each have 0g per 330ml. |
I want to know how much sugar I would drink from the whole bottle, not just from 100ml. |
| Caffeine and sweeteners |
Read the ingredients if either matters to you. The listed zero-sugar colas contain sweeteners and caffeine flavouring; Fanta describes its Orange glass bottles as caffeine free, but lists 4.5g sugars per 100ml. |
I might want to avoid caffeine, sugar or sweeteners; choosing for one of those reasons does not settle the others. |
| Glass and pack size |
Confirm that the exact listing says glass bottles. Your Coca-Cola UK lists Coca-Cola Zero Sugar and Fanta Orange in 24 x 330ml glass packs; Tesco lists Pepsi MAX in a 6 x 330ml glass pack. |
Glass matters to me, but I also need a pack size that suits how often I will drink it. |
| Current availability |
Check the exact retailer listing before relying on a particular pack. Tesco’s Pepsi MAX 6 x 330ml glass-bottle listing was out of stock when checked. |
If I am buying for a particular occasion, I need to confirm that the glass-bottle pack can be ordered now. |
Common buying mistakes
-
Judging the drink by its glass bottle
Glass packaging does not tell you whether the drink contains sugar, sweeteners or caffeine flavouring. The listed original colas and zero-sugar colas differ on these points despite sharing a glass format.
Read the nutrition panel and ingredients first; choose the container format separately.
-
Overlooking the sugar in one original-cola bottle
Tesco lists 35g sugars in a 330ml Coca-Cola Original serving, and Regency Foods lists 36g in a 330ml regular Pepsi glass bottle. For context, the NHS recommends that adults have no more than 30g of free sugars a day.
If sugar is a deciding factor, compare those figures with the 0g-sugar glass-bottle colas rather than assuming the drinks are interchangeable.
-
Assuming zero sugar also means caffeine free
The listed Coca-Cola Zero Sugar and Pepsi MAX glass bottles contain caffeine flavouring. Their 0g-sugar nutrition figures do not establish how much caffeine a bottle contains.
If you are avoiding caffeine, look for an explicit caffeine-free statement; Fanta makes one for its Orange glass-bottle drink, which still contains sugar.
-
Assuming every listed pack is ready to order
Retailer stock can differ even when a glass-bottle product has a listing. Tesco’s Pepsi MAX glass-bottle pack was marked out of stock when checked.
Confirm the container material, pack size and current stock on the specific product page before planning around it.

Frequently asked questions
Is a glass-bottle fizzy drink a pre-workout snack?
It can be an occasional drink alongside a food snack, but the glass bottle alone says nothing about its sugar or caffeine content. Check the particular drink’s nutrition panel and ingredients against what you want before exercise.
Which listed glass-bottle colas contain no sugar?
Your Coca-Cola UK lists Coca-Cola Zero Sugar 24 x 330ml glass bottles with 0g sugars per bottle, while Tesco lists the same figure for Pepsi MAX 6 x 330ml glass bottles. Both ingredient lists include sweeteners and caffeine flavouring.
Is there a caffeine-free glass-bottle option?
Your Coca-Cola UK describes its Fanta Orange 24 x 330ml glass-bottle drink as caffeine free. Its nutrition panel lists 4.5g sugars per 100ml, so it is not a zero-sugar option.
