Cafec Abaca T-90

Cafec's fast-draining T-90 abaca clears the bed the instant the switch opens, so the immersion releases clean without clogging.

Notes

Sieve coarse grounds to remove fines and chaff, and rinse a fast Cafec Abaca paper thoroughly. Break the crust before firm agitation, release onto a clear server, then add bypass gradually while tasting instead of diluting all at once.
