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 3pm 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.”

  • It does get me curious to try it. I like the idea of this drink being stimulate free and using more natural ingredients. It definitely sounds like a better and healthier alternative to those energy drinks currently on the market at the moment. Haven’t seen these around in stores yet but i;ll definitely be keeping an eye out!
