The humble thirst quencher consumed by gladiators, farmers, and philosophers alike turned out to be the very first hydration elixir that kept ancient minds sharp and bodies healthy.
Our modern take on that recipe has been reimagined to cut through the chaos of modern life – getting that electrolyte balance in evidence based ratios, and leveraging all we now know about the super powers of red-wine vinegar.
Why Posca Works
Picture a salty gladiator bath for your gut. The higher solute level briefly pulls a little water inward, then releases fluid plus minerals over time – giving you drip‑feed hydration instead of a flood. Studies link hypertonic drinks with slower gastric emptying and better fluid retention.
Posca’s solute concentration sits just above that of your bloodstream (≈ 300 mOsm/kg). This slight edge pulls a trick of osmosis, water is retained in the gut a touch longer, then released gradually alongside minerals.
Result:“More goodness per sip.”
A hypertonic drink is like a slow-release wellness shot, it hydrates and fuels your body with the extras it actually needs.
Every can carries sodium, potassium, magnesium and calcium in evidence-based ratios. These minerals replace sweat losses, keep nerves firing and stop muscles cramping so you can march on.

Chosen ratios align with sports‑nutrition research on optimal rehydration as well as actually tasting good!
Instead of sugary fruit juice, Posca leans on polyphenol-rich red-wine vinegar. Organic acids support a healthy microbiome and help smooth post-meal glucose swings while antioxidants guard your cells.
Red‑wine vinegar supplies acetic acid and resveratrol – both shown to aid blood‑sugar control, appetite regulation and antioxidant defence.
It's richer in polyphenols (5X) (anthocyanins, catechins, tannins) than ACV which supports metabolism, immunity & gut health. (García-Ruiz, 2021)
Resveratrol – exclusive to grapes.
Linked to heart health, anti-aging & anti-inflammation.
(Baur & Sinclair, 2006)
It has a higher antioxidant load (ORAC rating) than ACV which gives more powerful free radical defence. (Figueiredo-González, 2020)
Red wine vinegar has a milder acidity making it easier on throat & gut, better for regular hydration which also allows it not to be too heavily diluted, ensuring you get the benefits of the ingredient and not just a little bit of flavour.
Grapes also use ~50% less water/kg than apples in Australia. (Aust. Ag. Resources, 2023)
No glucose roller-coaster, no caffeine jitters, just crisp bubbles and 12 guilt-free calories.
Zero added sugar means no roller coaster. Organic acids may even blunt carb absorption from your next meal.
