How to make good tea
A LessWrong post applies rationalist principles to tea brewing, going viral with precise measurements.
A post titled 'How to make good tea' by user RobertM has gained significant traction on the rationalist community forum LessWrong. The guide applies a systematic, optimization-focused approach typically reserved for technical problems to the everyday ritual of tea brewing. It begins with simple marginal improvements for beginners, like reducing steep time from 4-5 to 3 minutes for black tea and using cooler water (175°F/80C) for greens. The core argument is that moving beyond "bad tea" requires treating brewing as a precise operation.
The author outlines hard requirements: high-quality loose-leaf tea, a scale precise to 0.1g, and a proper infuser. The post then provides a rational framework for exploration, advising against "sunk cost fallacy tea" and suggesting efficient sampling strategies at local stores or online vendors. It categorizes the vast tea landscape into clusters and styles, encouraging methodical tasting to discover personal preference within categories like black, oolong, and green. The viral appeal lies in its application of calibration, measurement, and iterative testing—cornerstones of rationalist and tech culture—to a seemingly mundane domestic activity.
- Recommends precise measurements: 2-3g of loose leaf tea, steep for 3 minutes for black, 2 minutes for green.
- Advocates for temperature control: 175°F (80°C) for most green teas, contrasting with common boiling-water practice.
- Provides a rational sourcing framework: sample small quantities (5-10g) to efficiently explore varieties without commitment.
