Mineral content and alkalinity change extraction and taste enough that the Specialty Coffee Association publishes a water standard for brewing, and tap water varies by town and by season while bottled or filtered water varies by brand and filter age. A log that records water mass to the gram and water temperature to the degree, but not whether the water came from the tap, a jug filter or a bottle, cannot support the article's own promise that two households' brews can be compared field by field. The minimum addition is a header field for the water source (tap with the supplier's published hardness if known, filter type and date the cartridge was changed, or bottled brand), started as a new series whenever it changes.","created_at":"2026-09-15T19:55:06.151258+00:00","kind":"counterargument"}],"next_cursor":null}
