Cosmo Plum

NewBack in StockSweet
Cosmo Plum is a honey-processed lot of caturra and castillo, harvested around Buesaco in Nariño. The farms sit on volcanic soil between 1,600 and 2,000 metres. It’s a collective lot, made possible through the work with Fusion Coffee Exporters and Nordic Approach. The honey process is what builds the sweetness and the jammy character here. Tasting like dark plum, purple grapes and brown sugar.

FROM ORIGIN TO CUP

The farms around Buesaco sit on volcanic soil between 1600 and 2000 masl, where the altitude slows down the ripening of the cherries and concentrates the sugar this cup runs on. The lot is pooled from several producers through Fusion Coffee Exporters and Nordic Approach, and processed together as a honey, which means part of the sticky mucilage is left on the seed through drying. That layer is where the plum and grape sweetness builds, and it gives the coffee a slightly heavier body than a washed lot from the same farms would carry.

Origin

The farms sit around Buesaco in Nariño, Colombia, between 1600 and 2000 masl. Volcanic soil and high altitude slow the cherries and build the sugar content behind the sweetness. It is a collective lot, pulled from several small producers.

Varietal

A field blend of Caturra and Castillo. Caturra brings sweetness and a clean structure, Castillo brings body. Processed together as a honey they read as one round, fruit-driven cup.

Processing

Honey. The cherries are pulped, but part of the mucilage layer stays on the seed through drying. That is where the plum and grape sweetness builds, and it gives the coffee more body than a fully washed version would.

Intervention level

Medium. The honey process leaves fruit on the seed through drying, so the higher sweetness is built by the processing rather than left to the variety alone.

NOTES IN THE CUP

Cosmo Plum opens on dark plum: ripe, jammy, closer to stewed fruit than fresh. Purple grapes follow, adding a juicy edge that keeps the cup moving. Brown sugar sits underneath everything and rounds off the finish. As espresso the body runs medium to heavy and the fruit notes turn syrupy, with the sweetness stretching long after the sip. It stays quite clean for a honey, with none of the heavy funk some processed lots carry. Through milk the plum softens into something closer to a fruit compote. A sweet, straightforward and round espresso.

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.
