Cosmo Plum

CleanSweet

Cosmo Plum is a honey-processed lot of Caturra and Castillo, harvested around Buesaco in Nariño, where the farms sit on volcanic soils between 1,600 and 2,000 metres. It’s a collective lot, brought together through our work with Fusion Coffee Exporters and Nordic Approach. Dark plum, purple grapes and brown sugar come through with good clarity and structure in the cup. Sweet, easy to drink, and the kind of Colombian profile we like to come back to.

FROM ORIGIN TO CUP

Cosmo Plum brings together coffees from several producers around Buesaco in Nariño, grown between 1600 and 2000 masl. The lot comes to us through Fusion Coffee Exporters and Nordic Approach and combines Caturra and Castillo, processed as a honey. It’s a sweet but well-defined cup, with dark plum, purple grapes and brown sugar, and good clarity and structure throughout.

Origin

Buesaco, Nariño, Colombia. The coffees in this lot come from several small producers, with farms sitting between 1600 and 2000 masl on the volcanic soils of the region. Rather than representing a single farm, the coffees are brought together into one collective lot.

Varietal

A blend of Caturra and Castillo, two varieties widely grown in Colombia. Rather than separating them, the varieties are combined within the lot and processed together. In the cup, we find good clarity and structure, with the fruit staying defined rather than becoming overly jammy.

Processing

Honey. After picking, the cherries are pulped while some of the sticky mucilage surrounding the seed is kept during drying. This sits between washed and natural processing in terms of how much fruit remains around the seed, while still producing a cup with good definition.

Intervention level

Low. This is a traditional honey process: the cherries are pulped, some of the mucilage is left around the seed, and the coffee is dried without additional fermentation or other processing stages.

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: 1:15
• Dose: 16.5 g
• Water: 250 g
• Brew time: 2:00 minutes to 2:30 minutes
• Temperature: 92°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 120g (8 g/sec, medium)
• 1:00 pour to 190g (3 g/sec, very low)
• 1:30 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.
