Posca Hydrate runs on red grape vinegar, the same ingredient the Romans drank 2,000 years ago.
Sounds rough. Tastes like a crisp, tangy soda with zero sugar.
The vinegar is not there for flavour. It's there for the gut-loving polyphenols and hydration that actually sticks around.
Still skeptical? Good.
So was everyone who is now hooked.
Try it anyway.
Elissa was ready to hate it.
Then she tried it.
The face says the rest.
Three delicious flavours that taste like they just gave regular drinks a slap in the mouth.
It's ancient wisdom meets modern science.
Posca is the actual drink Roman legions carried across a continent. Vinegar, salt, water - real hydration before anyone called it that.
We pulled the recipe forward, added electrolytes and bubbles, and built a clean-label hypertonic, hydration soda around it.
Zero sugar. Real bite. Hydration that pulls its weight.
The Ancient Roman Elixir to Fix Ya.
Zero sugar.
No 3pm crash,
no 2pm guilt.
Hypertonic hydration.
Hydrates for longer
than water.
Prebiotics that keep
your gut health
on your side.
Tastes like it gave regular
drinks a slap in the mouth.
Made in Australia.
Not imported novelty.
"From the first crack of the can, I was hit with bright, bold aromas and that tart, tangy kick of red wine vinegar which was more ‘refreshing zing’ than ‘salad dressing’."
"After weeks of testing, I can confidently say this is a game-changer. The results speak for themselves."
"Full of electrolytes and prebiotics, but
with 0% added sugar, this drink replenishes and protects you from everything from dehydration to lethargy. We’ve found Posca works well if we’ve just come back from the gym or a busy day, or the next morning after a big event or dinner with mates."
Hippocrates prescribed vinegar for health. We just made it taste less like punishment.
The red-wine vinegar base brings resveratrol and acetic acid proven to help your heart, balance your blood sugar, and stop your arteries from acting like a traffic jam on Punt Road.
It’s basically cardio… in a can.
Posca Hydrate also packs five times more polyphenols than your average drink.
Polyphenols are plant compounds (from things like grapes and berries) that help reduce oxidative stress that’s the cell-damage that happens from stress, bad food, and too much sun.
They keep your cells young, your recovery quick, and your energy stable.
Every can has the four key electrolytes your body sweats out:
Sodium – keeps water where it should be (not just leaving your body in a hurry).
Potassium – helps your muscles contract without cramping.
Magnesium – calms nerves and supports energy production.
Calcium – essential for muscle movement and nerve signals.
Your gut, brain, and blood vessels are constantly talking — a loop that shapes how you feel, think, recover, and age. Posca Hydrate’s vinegar base helps strengthen the gut barrier and feed beneficial bacteria, keeping inflammation in check and your immune system steady. When that gut–brain–vascular axis is running smoothly, your whole body performs better: clearer thinking, steadier energy, faster recovery, and healthier ageing.
Your body doesn’t just need water, it needs to keep water. Posca’s formula is hypertonic (fancy word for slightly saltier than your bloodstream, about 300 mOsm/kg). That means it holds water in your gut for a bit longer, so it can be absorbed slowly and properly.
This slow-release hydration helps your muscles, nerves, and brain keep firing properly. That’s the science behind better focus, smoother muscle movement, and not overheating like a broken laptop.
Good health isn’t about fixing problems later. It’s about keeping your body running smoothly now, so it doesn’t fall apart later.
Posca is low-calorie, stimulant-free, and built to help your body perform at its best without the sugar spikes or crashes. Posca Hydrate combines old-school wisdom with modern science to keep you hydrated, focused, and functioning like a legend not just today, but decades from now.
It’s not just a drink for after sport; it’s a long-term investment in feeling good, moving better, and living longer. Because it’s cooler to still be active at 90 than to peak at 25.
Pre or Post-Workout
Sweat it out. Sip it back.
Hydrate like a gladiator.
Posca Hydrate restores lost minerals with 4 key electrolytes, zero sugar and red wine vinegar. It’s regret free hydration for whatever you're up to.
Mid-Afternoon
When your brain hits ‘meh’, this hits back.
A mid-afternoon zing to shake off the fog. Electrolytes, gut love, and bold flavour in one Roman-style reset.
Goes well with lunch...
...or dinner, or with
any meal really...
More well-rounded than your typical health drink, but far better for you than a soft drink – Posca goes well with sushi or pizza or any dish that a zing or our salty, sweet, sour, refresher would improve.
Big Nights
You drank like Bacchus.
Now hydrate like Caesar.
Posca’s prebiotic vinegar + minerals = your next-morning saviour. No sugar. No regrets.
Drink during, pre or post the big night to bounce back tomorrow
Posca Hydrate is an hypertonic soda built around real electrolytes, prebiotics from red grape vinegar, and bold flavour, not sugar. Zero sugar, all the bubbles – its all the taste of a delicious grown up soda with the benefits of hydration and gut health support.
Sparkling water has bubbles, and that's the whole pitch. Posca Hydrate hydration soda has bubbles AND genuinely does something more than taste nice; hypertonic hydration, prebiotics, real bite.
A different category, not a better sparkling water.
Posca was the actual drink Roman legions carried for 2,000 years; vinegar, salt, water.
We pulled the recipe forward and built modern hydration soda around it.
Red grape vinegar, at low levels. It gives you the original Roman bite; tart, tangy lift, not salad dressing.
Zero grams of sugar. We use a natural zero-calorie sweetener found in fruit and fermented foods. No high-fructose corn syrup, no artificial nonsense
