Your Water — Custom Coffee Brew Water, Mixed for One Person (5 Sachets · 5 Gallons)
Your own brew water recipe, mixed for exactly one person: you. High-end coffee water used to mean building a home chemistry bench — a precision scale, a shelf of mineral salts, a spreadsheet, and an evening you'd rather spend brewing. This is the concierge version. Tell us what you want, we'll compute your recipe, weigh it on a 0.1 mg lab balance, and ship it with your numbers in the bag. Your part takes ten seconds: tear a tab, pour the powder into a gallon of distilled or RO water, swirl. How it works Click on the graph Pick your custom water on the graph (you'll see the numbers change as you click different areas; that's the actual recipe we'll make.* We weigh your full recipe at lab scale on a 0.1 mg analytical balance, blend it, and split it into gallon doses by mass. All minerals will be within +/- 5% of order. You get 5 identical sachets — each makes 1 gallon in distilled or RO water. About two months of daily cups, mixed fresh one gallon at a time. Your lab card ships in the bag — your water's target numbers and the exact doses that hit them, with your name on it. Your recipe stays on file, so reorders are one click. Why single-gallon sachets? Because fresh-mixed water beats stored water. A gallon is about ten cups — you'll drink it before it fades, then tear the next tab. Ten seconds, fresh again. Be real now Water is fine-tuning — the last 2%, not the first 98. If your beans are stale or your grind is fighting you, fix that first (we'll still be here). But if your brew is dialed and something's still a half-step off, water is usually the knob you haven't turned. Food-grade (FCC) minerals: magnesium sulfate, calcium chloride, potassium bicarbonate (sodium-free buffer). Dissolve in the jug, never in the machine. Price includes US shipping.
