Pistachio, Berries and 80mg of Caffeine: Testing Red Bull’s New Winter Edition

I headed to Red Bull HQ to taste the new Red Bull Winter Edition Pistachio & Berries. It might sound more like something you'd find in a gelato shop than your gym bag, but it also got me thinking about caffeine, training and when an energy boost actually makes sense.

I spend a slightly ridiculous amount of time testing things connected with fitness and performance. Watches, sensors, recovery technology, training equipment and anything else that promises to tell me something useful about what my body is doing tend to get my attention. So, an invitation to Red Bull HQ to taste a new product seemed like a fairly easy assignment.

Then they told me the flavour: Pistachio & Berries.

Not exactly what I was expecting.

The new Red Bull Winter Edition Pistachio & Berries, launching in the UK on 28 September 2026, combines pistachio and berries with caramel and creamy, nutty undertones. Pistachio has become difficult to avoid over the past year, helped enormously by the Dubai chocolate craze, but putting it into an energy drink is a rather different proposition.

According to figures supplied by Red Bull from Tastewise, online interest in pistachio has increased by 72% over the past 12 months, with the ingredient becoming one of the fastest-growing flavours within sweetened drinks. Clearly somebody at Red Bull decided it was time to find out what happens when you put one of the year's biggest food trends into a can.

So, naturally, I tried it.

First things first: what does it taste like?

I expected the pistachio to dominate, but it doesn't. The berries give it a fruitier flavour, followed by the softer caramel and creamy notes, with the pistachio sitting more subtly in the background. It's unusual, but not nearly as strange as the name might initially suggest.

There are both full-sugar and sugar-free versions, which is something I welcome because it gives you the choice depending on what you actually want from the drink.

But tasting it at Red Bull HQ also raised a more interesting question for RB100: where does an energy drink actually fit into training and performance?

Let's talk about the 80mg

A 250ml can of Red Bull Winter Edition contains 80mg of caffeine, along with taurine and B vitamins. That's roughly comparable to the caffeine in a cup of coffee, although the amount in coffee varies considerably depending on the beans, size and preparation.

Caffeine itself is hardly unusual in sport. From cyclists and runners to HYROX competitors and regular gym-goers, plenty of us use caffeine around training. The important difference is between drinking something because you enjoy it and deliberately using caffeine as part of your performance strategy.

There is good evidence behind the latter. The International Society of Sports Nutrition has concluded that caffeine supplementation can improve several aspects of exercise performance, including muscular endurance, movement velocity, sprinting, jumping and aerobic endurance, although responses vary between individuals.

That doesn't mean more caffeine equals more performance.

For most healthy adults, the UK Food Standards Agency advises that total caffeine consumption of up to 400mg per day is unlikely to cause adverse effects. That is total consumption, though, not 400mg on top of the three coffees you forgot you had before lunch.

And this is where I think tracking becomes useful.

If you're measuring everything else, why not your caffeine?

I've become increasingly interested in the relationship between training, recovery and the choices we make during the rest of the day. We happily monitor heart rate, sleep, HRV, steps, calories and training load, yet many of us couldn't tell you how much caffeine we've consumed.

I'm certainly not suggesting everyone needs another spreadsheet.

But if you regularly use coffee, pre-workout supplements or energy drinks, it is worth understanding the cumulative amount and, perhaps even more importantly, when you're consuming it.

There is little point squeezing a slightly better training session out of yourself late in the evening if the caffeine then disrupts your sleep and compromises recovery. Performance isn't just what happens during the hour you're exercising. It is also what happens during the other 23.

That's particularly relevant to something called a Winter Edition, because Red Bull is also positioning the new flavour for indoor social occasions such as games nights and watch parties. If caffeine affects your sleep, that is worth remembering before reaching for one late at night.

Fuel, stimulant or treat?

This is where I think we sometimes make sports nutrition unnecessarily complicated.

Not everything we consume needs to be labelled a health food, performance product or guilty pleasure. Sometimes you simply like something. The useful part is knowing what is in it and deciding whether it makes sense for what you're doing.

If I'm about to train, I think about hydration, nutrition, energy and what the session requires. If I'm recovering, the priorities change. If I'm sitting with friends watching sport, I'm not pretending that everything in my hand is part of some carefully calibrated performance protocol.

The full-sugar and sugar-free versions of Red Bull Winter Edition also make that difference more relevant. They aren't nutritionally interchangeable, so which you choose should depend on your preferences and circumstances rather than assuming one version is automatically right for every situation.

Would Pistachio & Berries make it into my gym bag?

Possibly – although I think it is more likely to make it into the fridge.

Flavour is entirely subjective, but I liked this more than I expected to. The berry flavour prevents it becoming overly creamy or nutty, and the pistachio is subtle enough that you're not left feeling as though somebody has liquefied a dessert.

What I enjoyed most about visiting Red Bull HQ, however, was being reminded that performance doesn't have to become joyless. I love measuring things, testing myself and finding ways to improve, but I'm also a great believer that fitness needs to fit into a life you actually enjoy living.

You can train hard, chase PBs, experiment with technology and still try a can of something because pistachio and berries sounds sufficiently strange that you want to know what it tastes like.

Sometimes curiosity is reason enough.

Red Bull Winter Edition Pistachio & Berries launches in the UK on 28 September 2026. It will be available in full-sugar and sugar-free versions, with 250ml cans at £1.80 RRP, 355ml at £2.20 and 473ml at £2.75. A 4 x 250ml multipack will have an RRP of £5.75.
