Cold Brew Studio

About

Cold brew is simple: coffee, water, time. Getting it right is the hard part — the grind that's perfect on one grinder is mud on another, and the batch you nailed last month is a guess by the time the bag runs out. Cold Brew Studio is a brewing companion built around your actual gear. DIAL IT IN Pick your grinder — 82 models with their real dials and burrs — and get a grind setting, ratio, and steep window tuned to it. A beautiful dial shows exactly where to land. Switch strength between ready-to-drink, concentrate, and jet fuel, or point anywhere on the ratio band and make it yours. KNOW YOUR NUMBERS Coffee, water, steep time, caffeine, and what the batch costs — down to the price per cup. Batch sizing snaps to fractions of your bag, so "half the bag" is one tap, not math. STEEP WITH CONFIDENCE Start a batch and get a live countdown with a taste window, not just a timer. Native alerts tell you when the window opens and before it closes. Your phone nudges you; the fridge does the rest. REMEMBER EVERY BEAN Scan a bag with your camera and the label reads itself. The bag promises blueberry and cocoa — after you brew, tap what you actually tasted. Your journal builds a memory of every bean: how you brewed it, how you rated it, what it really tastes like. Pick a bean you've brewed before and your settings come back with it. YOURS, PRIVATELY Everything lives on your device. An optional account syncs your journal between devices — no ads, no trackers, and your data is never sold. Brew something worth waiting for.
