Quick answer

Brew Thamani as a medium-light filter coffee: use a 1:16 ratio, water just off the boil, a medium-fine grind, and a pour over you finish in about three minutes. That keeps the raspberry and lime bright without letting the brown sugar turn bitter.

Why Thamani rewards a careful filter brew

Thamani is a Kenya from the Mbature Family with notes of raspberry, lime, and brown sugar. Those fruit and sugar notes are easy to muddy with too much agitation or water that is too cool, which can leave the cup tasting flat or woody.

A filter brew gives you more control over extraction than immersion methods, so you can taste and adjust while the coffee is still fresh. If you already enjoy African coffee, this is a straightforward bean to work with once you lock in your grind and pour speed.

The trade-off: clarity versus body

A clean filter cup highlights Thamani's lime and raspberry, but it will not give you the heavier mouthfeel of a French press or espresso. If you want more body, grind slightly finer or use a touch less water, but expect the fruit to soften.

Freshness matters more than any single gadget. Thamani is a washed-style Kenyan lot, so its delicate notes fade faster than a dark roast. Buy in amounts you will finish within a few weeks and store the bag sealed and cool.

Step-by-step Thamani filter brew

  1. Weigh 15 g of Thamani and heat water: Use a scale to dose 15 g of whole-bean Thamani, then heat about 250 g of water to 94–96°C (just off the boil). Rinse your paper filter with hot water and discard the rinse. Common mistake: guessing the dose. A scale is the only way to repeat the ratio.
  2. Grind medium-fine: Grind just before brewing to a texture like fine sea salt. If your grinder has settings, start one step finer than you would for a drip machine. Checkpoint: if the brew drains in under two minutes, grind finer next time; if it stalls past four minutes, go coarser.
  3. Bloom with 45 g of water: Start your timer and pour 45 g of water over the grounds, covering all of them. Wait 30–45 seconds while the bed settles. Common mistake: skipping the bloom. Fresh coffee releases gas, and blooming prevents uneven extraction.
  4. Pour in two gentle stages: At 0:45, pour steadily to 150 g total, keeping the water level below the rim. At 1:30, pour to 250 g. Avoid pouring directly onto the paper filter. Checkpoint: keep the bed flat. If you see channels or dry patches, slow your pour and pour closer to the bed.
  5. Let it drain and taste: The brew should finish draining between 2:45 and 3:30. Swirl the server, let the cup cool for two minutes, then taste. If it tastes sharp or thin, grind finer or raise the water temperature slightly; if it tastes dry or bitter, grind coarser or shorten the finish.
