Our Philosophy
SOURCE WELL, ROAST CAREFULLY, SHIP FRESH

Our Roastery
Onyx Coffee Lab is a small specialty roastery in Cluj, roasting in small batches so every bag of beans arrives at peak flavor.
We source carefully, roast with patience, and cup every lot before it ships. Whether you order online or visit for a tasting, the goal is the same — coffee that genuinely tastes good.
Most of our customers come back for more, which tells us the approach is working. That keeps us honest and keeps us roasting.
What our neighbours say
The beans arrived within days of roasting and you could taste the difference. I will be ordering again.
The single origin I tried was unlike anything I had brewed at home before. Really opened my eyes.
They took the time to explain which roast would suit my setup at home. That kind of help is rare and really appreciated.
I came to a tasting not knowing much about coffee and left with a bag of beans I genuinely love.
Friendly, knowledgeable, and genuinely passionate about coffee. The tasting was a great evening out.
The house blend is my go-to for everyday drinking. Reliable, balanced, and always freshly roasted.
Fresh, clearly roasted with care, and delivered quickly. Exactly what I wanted from a local roastery.
My morning cup has never been the same since I started ordering from Onyx. Consistently fresh and full of flavor.
I appreciate that they roast in small batches and actually put the roast date on the bag. It shows in every cup.
