Reviews
Cleaner cup than my AeroPress, and I barely noticed the weight on a three-day hike through the Ardennes.
Sander de Vries · Pre-production tester
I was sceptical about the filter, but it keeps every bit of grit out. My morning routine is now just this straw and hot water.

Frequently asked questions
Dial in your brew
Swap Brewline's standard filter tip for one of three optional tips, each tuned to a different brewing style.
French Press tip
100 µm mesh
Full-bodied, rich coffee with more oils and a heavier mouthfeel. The closest to a classic French press brew.
€14.95
Pour-over tip
45 µm mesh
Clean, bright, and nuanced. Finer filtration lets more subtle flavour notes come through for a lighter cup.
€16.95
Espresso tip
60/25 µm double-layer mesh
Maximum filtration for the smoothest possible cup. Two mesh layers catch even the finest particles.
