What is the xBloom Studio?¶

The xBloom Studio is an automated pour-over brewer: it grinds the beans, weighs the dose and pours water at a set temperature on a programmed pour schedule. That makes a recipe repeatable — the same numbers give the same cup.

How to read a recipe¶

Each coffee page lists:

• Dose (g) and ratio (e.g. 1:15 → 16 g coffee to 240 ml water),
• Grind (the lower the number, the finer),
• Temperature and grinder RPM,
• Pours — the bloom (initial wetting) and the following pours, with a pattern (spiral / centered),
• The dial-in story — how the taste was reached.

The golden rule of dialing in¶

• Sour / flat / watery → under-extracted → grind finer (lower number).
• Bitter / astringent / dry → over-extracted → grind coarser (or lower the temperature).
• Change one thing at a time and re-taste. Drink light roasts hot — they turn bitter as they cool.

Each recipe was dialed on one particular grinder and palate — treat it as a launch pad, not gospel. This is a non-commercial hobby ledger, unaffiliated with xBloom or any roaster.
