B75

How the B75 works

The B75 is the Timemore flat-bottom dripper with 75-degree walls and an almost fully open base — the "crystal eye" — held by thin fins. It takes the same wave filters as the Kalita, but without the three-hole floor: drawdown is much faster.

The result pairs the even extraction of a flat bed with a quick drawdown — flat-bottom sweetness and body with extra clarity and less risk of over-extraction. The shallow bed is forgiving and takes a finer grind than the Kalita.

Grind, ratio and temperature

Start from a medium-fine grind — one step finer than the Kalita; the open base makes up for it —, a ratio near 1:16 and water from 90 to 94°C depending on roast (light at the top of the range, dark at the bottom). The house recipe uses 92°C.

Since flow is fast, grind is the contact-time lever: a thin, sour cup wants finer; an astringent, dry one wants coarser. Keep agitation low — a gentle agitation at the bloom is enough, the shallow bed reacts quickly to turbulence.

The house recipe

The Coffee Chronicler (Asser Christensen) three-pour recipe: a bloom with gentle agitation, one controlled pour to 150 ml and a final one in slow circles to 250 ml, ending the pour around 1:45. With the fast B75 drawdown the cup finishes near 2:30 — sweet, clean and with just-right body.

Common mistakes

Using your Kalita grind unchanged — on the B75 it drains too fast and under-extracts; pouring hard and digging into the shallow bed; skipping the filter rinse; and buying the wrong paper — the B75 takes Kalita wave filters (155), not cones. Without a temperature-controlled kettle, freshly boiled water rested for 30 seconds does the job.
