SMART VACUUM COFFEE JAR + APP
A smart vacuum jar designed to get freshly roasted beans ready sooner, show when to brew, and keep their flavour for longer.

MORE GOOD CUPS FROM EVERY BAG
Brew too early and excess CO₂ can get in the way. Leave the bag too long and its flavour starts to fade. Roast Peak helps you find the window in between and make more of it.
A roast date leaves you counting days. Roast Peak follows your beans as they release gas, then helps you recognise their best brewing window.
Active pressure sensing follows CO₂ release. Our algorithm identifies the peak brewing window, with the status shown on the lid and an alert in the app.
You bought fresh beans because you want to taste them. Active vacuum helps CO₂ leave the beans, bringing the brewing window forward.
We’re developing active degassing to shorten the rest before brewing. The right amount of rest depends on the coffee and roast.
Enjoy the bag over more good cups. Automatic vacuum storage limits oxygen exposure to help protect the flavours that fade as coffee ages.
After taking your dose, close the jar again. It maintains the vacuum automatically, without repeated pumping by hand.
A CLEAR ANSWER TO “IS IT READY YET?”
See the brewing window for each coffee. The light ring shows its status, and the app alerts you when it’s time to brew.

THE OPTIMAL BREWING WINDOW
Active pressure sensing follows CO₂ release. Our algorithm identifies the peak brewing window, the lid lights up, and the app alerts you when it’s time to brew.
Illustrative curves explain the intended benefit. Timing varies with the coffee, roast and brewing method. Live jar integration and readiness alerts are in development.
Still resting. Give the beans a little more time.

Fresh beans keep releasing gas after you close the lid. Roast Peak actively maintains the vacuum as they rest, then protects them between brews.
MORE THAN ONE COFFEE ON THE GO?
Keep each coffee in its own jar. The app tracks each coffee’s roast details and brewing window separately. Select one to find its jar with an LED flash and a short audio cue.

AT HOME. AT THE COFFEE BAR.
Fresh beans, a warm kitchen, and a coffee worth taking your time over.
Keep your beans beside the setup you already love.
FOR THE HOME BREWER
Give storage the same care you give your grind. Know which bag is ready, try a fresh roast sooner, and enjoy more of it before the flavours fade.
FOR CAFÉS & BARISTAS
Residual CO₂ affects wetting and extraction. Active pressure sensing and our algorithm identify the peak brewing window, while vacuum storage reduces oxygen exposure between doses.

FROM EARLY TESTING
We’re testing how active vacuum changes gas release and how much flavour the beans retain in storage.
In early experiments, the team reports around 30% faster degassing under active vacuum. Testing across different coffees and roasts is continuing.
Preliminary, team-reported result. Faster gas release is not a guaranteed reduction in resting time.
THE SAME COFFEE. TWO WAYS TO STORE IT.
In an informal team tasting, the jar sample retained distinct strawberry and grape notes after two to three weeks. Beans from the same roast stored in a paper bag tasted flatter.
An informal comparison of one coffee. Controlled tasting and broader validation are still to come.
Roast Peak combines automatic vacuum storage with active pressure sensing and our brewing-window algorithm. It brings the beans to their peak sooner, shows when to brew, and protects flavour between cups.
Roasting leaves CO₂ inside the beans. Too much residual gas can interfere with extraction. Resting lets excess gas escape, while limiting oxygen exposure helps slow the loss of flavour.
The team reports around 30% faster degassing in early experiments. That is a preliminary degassing result, not a guaranteed reduction in resting time. Tests across more coffees and roasts are still needed.
Roast Peak uses active pressure sensing to follow CO₂ release from your beans. Our algorithm uses those readings to identify the peak brewing window. The light ring shows the coffee’s status, and the app sends you a notification when it’s ready to brew.
