FAQs | Posca Hydrate – Electrolyte Drink Questions Answered

What is Posca Hydrate?

The Ancient Romans cracked rehydration first: vinegar + salts + water.
Two thousand years ago Roman gladiators drank Posca to replace sweat and stay sharp. We’ve taken that recipe, stripped out the nasties, and rebuilt it with modern science.

The result? Australia’s first sugar-free hypertonic hydration soda – packed with four essential electrolytes, red grape vinegar (a natural antioxidant and gut hero), bubbles, and zero sugar. A hypertonic hit with a bracing, tingling reset and hydration that sticks around, instead of ghosting you ten minutes later.

Sustained hydration. No sugar. No crash. No regrets.

Who created Posca Hydrate?

Our co-founder Merrick Watts stumbled on the story of Posca in 2021 while nerding out on the history of wine. As a fitness nut (and someone who survived SAS Australia), he figured: if it kept armies marching 2,000 years ago, maybe it can keep us charging through modern life.

So he started mixing batches on his kitchen bench, trialling it mid-workouts, and obsessing over taste and function. Three years later – refined with the same rigour he brings to comedy and wine – Posca Hydrate was born.

What was the original Posca recipe?

The Romans drank a mix of water, vinegar, salt and flavours they had available to them... like sticks... rocks... sticks... or herbs (if they were fancy). Safe, refreshing, electrolyte-rich it was the drink that quenched the thirsts of gladiators, peasants, emperors – everyone had their sip.
It was hydration for the people.

How does Posca Hydrate blend ancient wisdom with modern science?

We kept the vinegar. We kept the minerals. We swapped out the dodgy well water for sparkling, clean fizz and layered in medical research. And we left out the sticks...

Hypertonic hydration = more minerals for better retention.

Red grape vinegar = antioxidants, gut and liver support, brain blood flow.

Zero sugar = no crash, no regrets.

Ancient recipe. Modern function.

Do I need to be an athlete to drink Posca Hydrate?

Absolutely not. Posca Hydrate isn’t just for gym junkies. It’s for:

• Post-workout recovery

• Hot days at the beach

• Music festivals

• That 3pm desk slump

If you sweat, stress or celebrate, Posca Hydrate is for you.

Is Posca Hydrate an energy drink?

Nope. We’re the opposite. Energy drinks jack you up with sugar and stimulants, then drop you flat.

Posca Hydrate is sugar-free, stimulant-free, and crash-free. It hydrates, supports focus, and keeps you steady. Bubbles, not buzz.

Is Posca Hydrate a sports drink?

Nope, it's hydration soda - like if your sports drink and your better-for-you soda had a baby (that's also their ancient grand parent?).
Posca Hydrate is the original hydration soda.
In ancient times the Romans drank it to replenish sweat.
Today, we’ve upgraded it with electrolytes, fizz, and flavours that actually taste good.

We call it The Elixir to Fix Ya.

Can Posca Hydrate replace water?

Not quite. Water is your base. Posca Hydrate is your upgrade – for when you need hydration that lasts longer and works harder.

Does Posca Hydrate contain caffeine?

Zero. None. Nada.
Posca Hydrate has no stimulants.
Just bubbles.
Bubbles are nice.

Is Posca Hydrate Australian made?

What are the health benefits?

Posca Hydrate supports:

• Sustained hydration (thanks to its hypertonic formula)

• Electrolyte retention (less lost through urine)

• Gut, liver, and immune health (thanks to red wine vinegar) 

• Brain clarity (increased blood flow, better blood sugar regulation)

Think of it as your tool for better health. It’s about keeping your body running smoothly now, so it doesn’t fall apart later.

Posca Hydrate 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 activity; 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.

Is it safe for kids or pregnant women?

By law, as a Formulated Supplementary Sports Drink, we must display a warning: not suitable for under 15s or pregnant women.

The reason?

We skipped the sugar and added bubbles. It’s regulation red tape, not risk.

If Posca Hydrate added one and a half teaspoons of sugar per can (6.6g to be precise) we would be classified as an "Electrolyte Drink".
Because Electrolyte drinks must contain carbohydrates. No warnings needed.

If Posca Hydrate didn't have its delightfully refreshing bubbles, it would be a "Formulated Beverage", which is any ready to drink, water based beverage that contains vitamins and minerals. Seriously. Same ingredients, but without the bubbles.

So while our good friends at Food Standards navigate this exciting time in Australian beverage innovation, we want to assure anyone who is targeted by our warning, that by removing sugar and adding bubbles, we actually have your best interests at heart. And we love a challenge.

Can Posca Hydrate help with hangovers?

Let’s just say… dehydration and electrolyte loss are two major culprits behind hangovers. Posca Hydrate restores both. Plus, its antioxidants and red wine vinegar support your liver, gut, and immune system.

The Romans definitely drank it after a big night too. Probably.

Why red grape vinegar?

Because it’s a powerhouse.

Clinical studies show it’s loaded with antioxidants, supports gut and liver health, regulates blood sugar, and even helps fight brain fog.

It has up to 5x the antioxidants of apple cider vinegar and even has resveratrol - the compound that makes grapes so good for heart health, anti-aging & anti-inflammation.

It's also easier on the taste buds - compare a spoonful of apple cider vinegar against red grape vinegar and see if you can see why the Roman's loved this magic ingredient.

How many Poscas can I drink a day?

We recommend no more than 7 cans in a day based on recommended magnesium supplement intake from our friends at the Australian National Health and Medical Research Council. If you’ve got specific health concerns, check in with your healthcare professional.
