Berry Blues

NewBack in StockFunkyRound
Berry Blues is back, a silky anaerobic natural from Esayas Beriso, grown high in Oromia, Ethiopia. This year’s harvest is shade-dried and has plenty of dark fruit notes and a boozy edge: grape soda up front, myrtle liquor behind it, and a cashew-butter richness that creates a buttery body and creamy mouthfeel.

FROM ORIGIN TO CUP

Esayas Beriso grows this high in Oromia, at an altitude of 2350 masl, where the thin, cool air slows the maturation of the cherries down. The heirloom cherries ferment anaerobically, sealed and deprived of oxygen, then dry slowly in the shade with the outer fruit layer still on. That slow, shaded drying is where the silky, buttery texture comes from, and the anaerobic fermentation pushes the fruit toward the darker, boozier end: grape soda and myrtle liquor. The cashew-butter note is less a flavour added than the way the body feels.

Origin

This lot sits in in Oromia, Ethiopia, at an altitude of 2350 masl. At that height the cherries mature more slowly and concentrate their natural sugars, which builds the sweetness and the silky body.

Varietal

Heirloom, the uncatalogued indigenous Ethiopian varieties behind the layered complex fruity profiles. For this coffee they lean more towards purple fruits and boozy profile due to the anaerobic natural processing.

Processing

Anaerobic natural, shade-dried. The whole cherries ferment sealed, without oxygen, then they dry slowly in the shade with the fruit still intact. The sealed fermentation builds the interesting grape and myrtle notes, and the slow shade drying is what gives the cup its final buttery mouthfeel and silky texture.

Intervention level

Medium. The sealed anaerobic fermentation is an extra controlled step, and the slow shade drying carries the profile from there.

NOTES IN THE CUP

The first sip hits you with grape soda notes first, sweet and a little fizzy, more dark fruits and tart rather than bright. Myrtle liquor follows, boozy and herbal, the note that gives the cup its edge and complexity providing contrast and balance. Underneath sits cashew butter, less a flavour and more a texture, thick and smooth across the palate. The body stays silky and buttery the whole way through. As filter the dark fruit notes spread and the boozy note lifts and is more gentle; as espresso it turns rich and syrupy, and it carries easily through milk. Low in acidity, heavy in texture.

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.
