Hachi Geisha

Limited EditionCleanDelicate

A truly exceptional coffee from Diego Bermudez / Hachi Project. This Colombian washed Geisha is delicious and delicate with tasting notes of lemon, jasmine & honey – a very typical Geisha profile. Fermentation takes place in open tanks where temperature, pH, and duration is monitored and adjusted in real time. In this lot, there are no added yeasts or bacteria, but guided fermentation with the natural microbial population is performed to avoid over-fermentation, stagnation, or spoilage.

FROM ORIGIN TO CUP

Hachi Geisha Hinoka is a washed Geisha from Paraíso Farm in Cauca, Colombia, fermented with nothing added, and the cup is clean and delicate. The farm holds eight genetically selected Geisha lines and is also the birthplace of the Tena Biru variety. This lot was harvested in November 2025.

Origin

Paraíso Farm is in Tunía, in the Piendamó municipality of Cauca, at around 1950 masl. The climate there is temperate and humid, and the soils are volcanic, part of the upper Cauca River basin.

Varietal

Geisha traces back to Ethiopia and is known for a floral, tea-like cup with a lot of clarity. Washed and fermented with nothing added, it keeps that character intact here.

Processing

The coffee is washed, with the fermentation done in open tanks and the temperature, pH and timing monitored throughout. Only the microbes already present on the farm take part, with no added yeasts or bacteria. That keeps the cup clean and leaves the florals and citrus of the Geisha to come through on their own.

Intervention level

Low. This is a low-intervention coffee, and the producer calls it minimal intervention. The fermentation is watched closely, but nothing is added to it, so the variety and the farm shape the cup.

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.

General

For most grinders and most bars. Balanced, works black and with milk.

• Ratio: 1:2.5
• Dose: 18 g
• Yield: 45 g
• Brew time: 25 seconds
• Pressure: 9 bars
• Temperature: 93°C

For our roast level 1:2.5 ratio fully extracts, balances and opens the cup without thinning it compared to the classic 1:2.

Modern

Longer ratio, lower pressure, shorter contact. More clarity and acidity.

• Ratio: 1:3
• Dose: 18 g
• Yield: 54 g
• Brew time: 20 seconds
• Pressure: 6 bars
• Temperature: 93°C

A note on equipment: 1:3 relies on a flat burr set capable of a very even grind.
On an E65, E80 or Mythos this ratio often tastes watery. If that happens, pull back to 1:2.5.

Advanced (pressure profiled)
For machines with flow or pressure control. This is the showroom recipe.

• Ratio: 1:3
• Dose: 18 g
• Yield: 54 g
• Total brew time: 30 seconds to 1:00 total
• Pre-infusion at 2 bars (about 1 to 2 g/sec flow rate) until 1g in the cup, 15 to 30 seconds
• Main extraction: 6 bars until 18g yield. (about 5 to 6 g/sec flow rate)
• Post-infusion: 2 bars (about 1 to 2 g/sec flow rate) until 54g final yield
• Temperature 93°C

• Ratio: 1:16.6
• Dose: 15 g
• Water: 250 g
• Brew time: 2:30 minutes to 3 minutes
• Temperature: 95°C

Poring structure

Start your timer with the first pour. The weights below are the total water added.

• 0:00 pour to 50g (8 g/sec, medium)
• 0:30 pour to 100g (8 g/sec, medium)
• 1:00 pour to 250g (3 g/sec, very low)

Pouring very slowly keeps the bed open. Let the water draw down to finish the brew.

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.

Long ratio (for harder extraction)
For when extraction is more difficult: hard or heavily filtered water, a grinder past its best, or a dense lot.

1:18 ratio. 14g in, 250g out. 2:30 to 3:00. 97°C.
• 0:00 pour to 45g
• 0:30 pour to 90g
• 1:00 pour to 250g

1:20 ratio. 12.5g in, 250g out. 2:15 to 2:45. 97°C.
• 0:00 pour to 40g
• 0:30 pour to 80g
• 1:00 pour to 250g

Adjusting

• If the cup tastes thin, dry or harsh: raise the dose. Move from 15g to 16 or 16.5g at the same 250g yield.
• If espresso tastes watery at 1:3: shorten to 1:2.5 before touching the grind.
• Water: very low or very high TDS shifts everything. Check the water before changing the recipe. If the water cannot be changed, go to the long ratio recipes.
