The original sports drink of the ancient world has arrived to keep warriors hydrated. And yes, it’s sugar-free.

From comedian and SAS Australia competitor, Merrick Watts, POSCA Hydrate is a reimagining of the sip that fuelled armies and gladiators in ancient times. But while the old-world recipe was anything but palatable, Watts’s modern spin is “downright delicious.”

“It was during the depths of the COVID lockdown of 2021 that I came across the original Posca recipe and its fascinating stories, buried in the (online) history books. It got me thinking that there is a thing or two we can learn about hydration and health from the ancient world. Given Posca was the drink of actual gladiators, there is no doubt it is the original sports drink.”

What’s the POSCA Hydrate difference?

POSCA Hydrate is Australia’s first sparkling hypotonic drink in a can and the go-to hydration helper for anyone active.

Completely stimulant-free, it uses an all-natural formulation of four essential electrolytes and red wine vinegar to deliver lasting hydration. ‘Hypertonic’ means it contains large amounts of minerals to help invigorate, support and refresh busy humans – whether it’s post-gym, or when the 3 pm office crash rolls around.

Why vinegar?

Drawing on extensive research, Watts explains that red wine vinegar is a fantastic source of antioxidants and dishes up a host of benefits including improved gut and immune health and better blood sugar regulation.

Refined for quality & health

Frustrated with the lack of sugar-free sports drinks available in Australia, Watts combined his passion for health with his wine-making prowess to create the first batch of POSCA Hydrate in 2021. It was sparkling, fresh and 100% sugar-free.

Over the past three years, the reimagined sip underwent rigorous tweaks to reach the premium tastes and qualities it offers today, “without a crash, without sugar, without stimulants, without regrets,” explains Watts.

Dr Dan Pronk (ex-SAS) adds that proper hydration is a challenge for many people, with research suggesting that around 80% of people experience symptoms of dehydration daily. Hydration drinks help to replenish water, electrolytes and energy, however not all sports drinks are created equal.

“Where a lot of people go wrong or become confused in their search for hydration support is choosing a sports drink that’s high in sugar, or opting for an energy drink, which typically contains substantial amounts of caffeine, added sugars, additives and other stimulants. The effects of these drinks are short-lived, and they are unlikely to provide any sustained hydration or enhanced electrolyte retention.”

  • I have never seen or heard of this product before. It looks interesting and I would be keen to try it especially if it is good for hydration as I am always dehydrated and could be something to help me with this. I love the sound of all flavour but the lemon zest flavour sounds very refreshing.


  • I have never heard or seen of this before, so thanks for pointing it out. I wish it was more widely available in single cans, as I’d like to taste it before buying a 12 pack.


  • Ive never seen this product in store before but it sounds quite interesting and something that would be right up my alley. I like that it’s 100% sugar free and without the stimulates that often come with other drinks similar to this. It makes This more appealing to me as a better drink option


  • This is the first time I’ve seen this brand of sports drink. I like the sound of these flavours, very refreshing and tart. Is it only available online and through certain gyms, or will they be available in supermarkets? I’d love to try each flavour before buying a case through Amazon.


  • I had not heard of these before. Honestly I have never purchased a sports drink for myself before, only for our kids who train heavily. Having now read the article I will keep my eye out for these and grab a couple for the kids to try as well as myself πŸ™‚


  • I’ve never heard of his ancient Posca recipe and I find it fascinating. Old remedies and tonics often have something to them. They’re likely the basis of all medicines. I love that’s it’s sugar free and sparkling and refreshing would suit me fine. I don’t go for energy drinks usually but the flavours are tempting so I might give this a go.


  • I’m not gonna lie, some days I feel like I’m running on fumes after running around after my two little ones. I’d be keen to try this though and see if it gives me more energy.


  • This looks good! I’m so anti sports drinks because of the sugar and caffeinated drinks because of the caffeine. Although I’ll have a hydrolyte or equivalent from time to time, the taste is far from nice!

    I’ll actually try these now I’m aware of them if I find them.
