How to brew with Brewline
Two methods, three steps each. Pick whichever suits your setup.
Boil water in your cup
Place a steel or titanium cup directly on your stove and bring 200 to 250 ml of water to a boil. This is the same cup you will brew and drink from: one vessel for the entire process, nothing to pour or transfer.
Add grounds and stir with Brewline
Remove the cup from heat and let the water cool for 30 seconds (ideal range: 90 to 96 degrees Celsius). Add 12 to 15 g of coarse grounds and stir with the Brewline straw itself: no spoon needed. Steep for 2 to 5 minutes. The longer you wait, the stronger the cup. Optionally add a splash of cold water after a few minutes to slow down extraction and bring the temperature into a gentler range.
Sip from the same cup
Insert Brewline and drink directly from the cup you boiled in. The micro-filter keeps all grounds out for smooth, clean coffee. No second vessel, no pouring, no waste. Boil, brew, drink: all from one cup.
Add grounds
Add 12 to 15 g of coarse coffee grounds directly into any mug or vessel. There is no special equipment needed; use your regular trail mug, a titanium cup, or even a wide-mouth insulated bottle. A hand grinder on coarse setting works perfectly, and pre-ground coffee in the right size is fine too.
Pour hot water
Add 200 to 250 ml of hot water. For best results, aim for a temperature between 90 and 96 degrees Celsius. Stir briefly to ensure all the grounds are saturated, then let the coffee steep for 2 to 5 minutes depending on your preferred strength. Longer steeps produce a bolder cup.
Sip clean coffee
Insert Brewline into the mug and drink. The micro-filter at the tip keeps all grounds out while you enjoy smooth, grit-free coffee. Because extraction continues as you sip, the flavour develops gradually from cup to cup. The last third of your brew will be the richest.
Works with any vessel
Brewline fits titanium mugs, ceramic cups, insulated bottles, and everything in between.
Titanium camp mugs
The natural pairing for ultralight setups. Titanium mugs cool quickly, giving you a wider drinking window before over-extraction.
Ceramic cups
At home or in a shelter, a regular ceramic mug works beautifully. The heat retention keeps your coffee warm while the filter does its job.
Insulated bottles
Wide-mouth insulated bottles retain heat for longer brews. Great for cold mornings when you want your coffee to stay warm throughout the steep.
