Cold Brew Studio does the dialing — ratio, grind, steep and cost — for the gear you already own. Then it learns what you like.
Pick your grinder, bean, and brewer. The dial answers in your grinder’s own clicks — and the recipe honors what your vessel actually holds.
The steep runs overnight. Your phone speaks up when the window opens — and again before it closes.
Rate it, tap what was off — the next recipe moves. Five clean stars pins that bean’s dialed-in brew.
Set it steeping before bed. Wake up to the good stuff.
