About

1518 Coffee

Features
Read full description

From specialty coffee lovers to specialty coffee lovers. 1518 does two things well: it reads the bag you just bought, and it helps you brew it better than you did last time. Everything else is in service of those two. SCAN THE BAG Point your phone at the label. Roaster, origin, producer, process, altitude, variety โ€” read off and turned into a proper coffee card. No typing, no forms. BREW IT RIGHT Guided timers for thirteen brewers, from the V60 and Chemex to the AeroPress, Pulsar, Switch and April Hybrid. Pour by pour, target weight on screen, a nudge when it is time to pour again. Change the dose and the whole recipe rescales with it. RECIPES IN THE GRINDER YOU OWN Recipes are written in Comandante clicks by convention, which helps nobody who owns something else. 1518 converts them: a ZP6 owner sees 3.4, not "34 clicks". TRAIN YOUR PALATE The taste lab gives you four levers โ€” grind, heat, water and time โ€” and shows how each one pushes the cup between sour and bitter, and where the sweet spot sits between them. It is the fastest way to understand why a brew went wrong. KNOW BEFORE YOU BREW Every coffee gets a predicted flavour profile from its process, altitude, variety and roast. It shows what it based the guess on, and never pretends to be a measurement. Taste it yourself and disagree โ€” every value is yours to change, and your reading always wins. KEEP EVERY BAG Sealed, open, finished. Days since you opened it, grams left, brews logged against it. The bags you are actually drinking sit at the top. AND THE ONES YOU DIDN'T BUY Photograph a bag on a shop shelf, or a cup someone poured you. Mark it seen, drank, or want to try. What you rate there teaches your taste profile too. SAVE YOUR OWN RECIPES The ratio that finally worked on that Ethiopian, kept and named, on every device you use. LEARN THE CRAFT Brewers, papers and grinders explained properly โ€” how each one drains, which paper suits it, what a burr set actually does. Drawn, not photographed. A DIRECTORY WORTH HAVING 220 roasters across 49 countries and 50 producers across 18, researched and checked by hand rather than scraped. Every website and handle verified against the roaster's own site. 1518 PLUS Free keeps ten coffees and the whole recipe library. Plus adds unlimited coffees, recipes of your own, and sync across every device you use.
