Dial in your brew

Swap Brewline's standard filter tip for one of three optional tips, each tuned to a different brewing style.

Brewline French Press filter tip, 100 micron mesh

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

Brewline Pour-over filter tip, 45 micron mesh

Pour-over tip

45 µm mesh

Clean, bright, and nuanced. Finer filtration lets more subtle flavour notes come through for a lighter cup.

Brewline Espresso filter tip, 60/25 micron double-layer mesh

Espresso tip

60/25 µm double-layer mesh

Maximum filtration for the smoothest possible cup. Two mesh layers catch even the finest particles.
