FROM ORIGIN TO CUP

Ndimi Factory sits in Kirinyaga at an altitude of 1700 masl, near Kerugoya on the foothills of Mount Kenya, and is one of several wet mills run by the Inoi Farmers Cooperative Society, registered back in 1954 and processing cherries from thousands of smallholder farmers. This is a washed AA field blend of the classic Kenyan varieties. Washing strips back the more intense fruit notes of processing and lets the acidity and the terroir do the talking, which is the traditional Kenyan route and the reason the cup reads so clean and structured. The result is bright and layered, with the fizz of the rhubarb note running right through it.

Origin

Ndimi Factory sits in Kirinyaga at 1700 masl, on the slopes of Mount Kenya. The area is known for coffees with high acidity and a full, juicy body, and this lot follows that closely.

Varietal

A field blend of SL28, SL39, Batian and Ruiri 11. SL28 is the historic Kenyan selection, known for intense blackcurrant acidity; Batian and Ruiri 11 are newer, disease-resistant varieties grown alongside it. Together they give the layered brightness Kenyans are known for.

Processing

Washed. The cherries are pulped and fermented, then washed and dried. It is the traditional Kenyan route, and it keeps the cup clean, bright and structured, with the varieties and the terroir doing the talking.

Intervention level

Low. Washed processing at a cooperative wet mill relies on clean fermentation and careful sorting rather than any manipulation of the profile.

NOTES IN THE CUP

Rhubarb Fizz opens sharp and lively, like rhubarb soda: tart, sweet, with a fizzy edge on the tongue. Blackcurrant follows, darker and juicier, giving the cup its depth. Orange notes round it off with a softer citrus sweetness and acidity that stretches into the finish. The acidity is what carries the fruit and keeps everything moving through the cup. As filter, it stays bright from hot to cool, and the layers separate more clearly as the temperature drops. The body is full and juicy rather than heavy. It is a Kenyan that rewards a clean brew and a bit of patience.

THE DAK BREW GUIDE

These are the recipes we use every day at the roastery and showroom. We keep them simple on purpose: water, ratio, grind size. The coffee does most of the work when the basics are right. Every setup is different, so treat these as a starting point. Adjust based on what you’re tasting and what your equipment gives you.

• Ratio: 1:3
• Dose: 18g in (adjust as needed for your basket)
• Yield: 54g out
• Brew time: 35 seconds (use this as a guideline rather than a strict target)
• Pressure: 6 bars if possible, otherwise 9 bars
• Temperature: 94 degrees (if possible to change the temperature)
• Pre-infusion time: 5-10 seconds (if possible)

• Ratio: 1:18 • Dose: 15g in • Yield: 270ml out • Brew time: 3:00 – 3:30 minutes • Temperature: 96 degrees • Bloom with 75g of water for 1 minute • First pour to 170g, second pour to 270g

Water is 98% of your cup, so it changes everything. Mineral content varies between cities, neighbourhoods, and even seasons depending on which reservoir is supplying the tap. If your water is hard (above 150ppm), switch to a soft bottled water around 50ppm. Too soft is always better than too hard. The difference in the cup is immediate.

Ethiopian coffees
Ethiopian beans are more brittle and produce more fines when grinding. Too much agitation during brewing pushes those fines into the filter and slows everything down. Keep agitation low. If the cup still tastes over-extracted or the drawdown stalls, grind coarser and extend the ratio or brew time slightly to compensate.

The look of a shot
Naked portafilters show you what’s happening, but what you see has no reliable connection to what you’ll taste. A messy-looking shot can taste clean, and a photogenic one can taste flat. Taste every shot, even the ones outside your parameters, and adjust from there.

Crema
Crema is gas escaping coffee under pressure. It carries very few desirable flavour compounds and can actually taste harsh. Removing it will almost always improve the cup. With light roast espresso especially, ignore the crema and focus on what’s in the liquid.

Freezing coffee
Freezing keeps coffee at peak flavour, but roasted coffee can’t be thawed and refrozen without losing quality. Vacuum-seal in single doses before freezing. When you’re ready to brew, grind it frozen. Don’t let it thaw first. Every grinder handles frozen beans without issue, and the results are often better. One dose out, the rest stays sealed.
