A new kind of drink, noticed.
A sourdough fermented drink, made in Edinburgh.
Quas is made with Scottish water, rye and barley, using a 180-year-old starter culture. Inspired by traditional kvass and left unfiltered, it tastes dry, malty and tangy, with the body of a proper adult drink.

There had to be more than orange juice.
When I stopped drinking alcohol in 2014, I still wanted something I could look forward to ordering.
I grew up in Estonia, where kvass was part of everyday life: after the sauna with my dad, and on holidays with my grandmother. Spotting it again in Tallinn in 2020, while I was finishing my PhD in Edinburgh, I wondered why a drink I had always loved was so hard to find here.
Experiments in my student room followed, until a family who had baked rye bread for generations shared the sourdough starter that became the heart of Quas. Today our small team still makes every batch in Edinburgh.
Built before the can opens.
Water, rye, barley and our sourdough culture become something dry, malty and layered.

LIVE Keep it cold
2–6°CLive Quas lives in the fridge.
Live Quas is unpasteurised, so its cultures stay active. The cold slows them down and keeps the flavour where it should be.
-
Chill it on arrival.
Unpack your box and put every can straight into the fridge. Live Quas must stay refrigerated at all times.
-
It keeps evolving.
The cultures stay active in the cold, so Quas slowly becomes more sour and less sweet with time.
-
Enjoy within six weeks.
Live Quas keeps for six weeks. Check the best-before date on the can.
