FruttaMax Thunder Max Energy Drink Syrup Original Zero

February 21st, 2026

This is another concentrated energy drink for use with SodaStream machine and is the sugar-free version of the already lower-than-normal in calories full fat version I reviewed previously. Make it up in a ratio of 1:23 with fizzy water and you should get an energy drink with 32mg/100ml. Compared to the full fat version, this version is slightly tangy in flavour, slightly more sour, but still a very nice bog standard energy drink – refreshing and drinkable!

FruttaMax Thunder Max Energy Drink Syrup Original

August 30th, 2025

If you have a SodaStream machine or similar carbonated water maker then you’ll know that the syrups you buy can make this a fantastic factory of fizzy wonder. I’ve reviewed SodaStream’s own-brand energy syrups before but this is a third-party offering from FruttaMax. When made up in a ratio of 1:23 with fizzy water you end up with an energy drink packing 32mg/100ml of caffeine according to the bottle. By my calculations for a smaller 450ml SodaStream bottle that requires about 20ml of syrup, or about 4 teaspoons. That isn’t very much at all, less than you’d typically use with genuine SodaStream syrups so I was concerned it might be a bit watery. Well, no, I was wrong! It’s spot on! What you end up with is a very passable ‘clone’ energy drink. It’s crisp and caramely, just as good if not better than most cheap clone cans. What’s even better is that this is the original full sugar version but only has 8 calories/100ml. The sugar-free version has got to be amazing if it wants to beat this. The concentrate will provide about 12 litres of diluted energy drink at a 1:23 ratio with water. You can of course mix this with still water if you don’t have a SodaStream machine but that might taste a bit weird.

Mio Energy Strawberry and Pineapple Smash

November 12th, 2022

Another concentrated drink which I added a couple of squirts to some carbonated Sodastream water. You do get a slight whiff of Strawberry, but honestly this drink is more like a normal, if slightly fruity, clone energy drink. It’s really nice! I found this in Target while on holiday in New York, and I’ve not found it in the UK yet but if I do, I’ll be buying several of them.

Mio Energy Wicked Blue Citrus

November 5th, 2022

This is an odd one to review as it’s a concentrate. I added a couple of small squirts to some carbonated water that I’d made using a Sodastream. It was okay, more like a watery raspberry than citrus in my opinion.

Sodastream Xtreme Energy 0 cal

August 31st, 2019

I’m a bit late to the whole Sodastream revelation having only just received one as a gift. I know they’ve been around for decades, but it’s just one of those things I kept putting off until another time. So, when I did eventually get one, I realised that most of the syrups are not available in the UK anymore. I imported a whole box of these Xtreme Energy 0 calorie syrup concentrates from a supplier in the US and fortunately it tastes pretty nice! I’ve guessed at the caffeine content for two reasons. Firstly, it doesn’t state on the bottle how much caffeine is in the syrup. Secondly, the amount of caffeine in your drink depends very much on how strong you make your drinks! This is a very strong tasting syrup and I’m still trying to figure out the best syrup/water ratio, but it’s sweet (you can’t tell it’s sugar free in my opinion) and refreshing. Now that I have a Sodastream, provided I can keep obtaining a supply of these syrups then this is likely to become my staple daily energy drink of choice. If only I could source it in the UK, that would save a whole load of transport costs (and carbon footprint!).
