The original hydration soda.

2,000 years in the making.

Before Gatorade. Before Coke. Roman soldiers had Posca - vinegar, water, salt. Zero sugar.

It worked then. It works now.

Posca is a hydration soda built on that same formula, updated with four electrolytes, Australian red grape vinegar, and a hypertonic formulation your body actually uses. Not a sports drink. Not a soft drink. The thing you reach for instead — at lunch, after training, at 3pm, after a big night. Three flavours. Nothing to apologise for on the label.

What’s inside every can

Built different.
Backed by science.

Most hydration drinks are just sugar and food colouring. Posca Hydrate was built from the ground up to actually work.

Electrolytes that
actually replenish

Sodium, potassium, magnesium and calcium; the four key electrolytes your body sweats out. Not a token sprinkle. The full picture.

Prebiotics for your
gut-brain axis

Built on a red grape vinegar base — a natural prebiotic that feeds your gut microbiome and supports the gut-brain connection.

Zero sugar.
Zero compromise.

Crash-free invigoration. No sugar, no artificial sweeteners, nothing to undo what you’ve worked for.

Ancient wisdom meets modern science

The world’s first sparkling, clean-label hypertonic soda — inspired by the Roman drink Posca, reformulated with modern nutritional science.

Posca Hydrate Grape

Smells like childhood. Tastes like you’ve grown up.

This isn’t candy. It just remembers what candy felt like, then flips the script with balance, bite, and the kind of restraint you wish you had back then.
I have no restraint - give it to me

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.

Frequently Asked Questions

Does it have caffeine?

Nope. Just clean, natural ingredients that work.
Is vinegar the main taste?

It’s there, but balanced. Bracing and refreshing, the perfect balance of salty, sweet and sour. Think tangy, not vinegary.
What’s hyper-hydration?

When we were creating Posca Hydrate we sent the liquids to labs in the US for osmolality testing. The results that came back surprised us – Posca Hydrate is hypertonic. Your gut will draw the nutrients from Posca into your body faster, along with the vinegar It means we pack a punch: electrolytes + vinegar = faster, longer-lasting hydration.
Can I drink this every day?

Yes. We made it for real life – hydrate without regrets.
