Seven-hundred and twenty milliliters of reverse osmosis,
deionized, carbon filtered water was heated to 90 C and poured
over an appropriate amount (35 g) of freshly ground coffee in
a Chemex Model CM-6A coffee brewer (Chemex Corp, Pittsfield,
MA, USA). The hot water was poured evenly on the ground coffee
through a Chemex bonded unbleached coffee filter, and 100 mL
was immediately poured into each snifter and served to the
panelists at approximately 70 C.
