Field notes
CZ Precision Lab organizes four Taiwanese teas around two preparation conditions: cold brewing and hot brewing. Its explorer box supplies two cold-brew and two hot-brew portions of each tea, for 16 total 3g portions. The homepage gives separate operating ranges for the formats—approximately 400ml of refrigerated water for cold brewing, and 250ml at 85–95°C for hot brewing—while noting that the settings are intended as stable starting points rather than universal answers.
