Plum Butter

NewBack in StockBestsellerRoundSweet
A natural from Eastern Uganda, which is not the first place most people look for a cup like this. Bulambuli Washing Station grows SL-14 and SL-28 high on the Mount Elgon side of the country, and the natural process pulls the fruit notes dark and deep: dark plum, grape cordial and a cacao finish.

FROM ORIGIN TO CUP

Uganda is still a unusual sight on any specialty coffee menu, and Plum Butter is the kind of lot that argues it should not be. Bulambuli Washing Station sits quite high in Eastern Uganda, on the slopes that climb toward Mount Elgon, at an altitude of 2300 masl. The SL-14 and SL-28 cherries dry whole as a natural, the fruit left on allowing the seed to ferment inside the pulp, which is where the dark plum and the grape cordial notes come from. The result is a deep, rich and chocolatey profile rather than bright and acidic, with a smooth body that carries the fruit notes. It reads closer to a dessert than to a high-toned washed coffee.

Origin

Bulambuli Washing Station sits in Eastern Uganda at an altitude2300 masl, on the slopes that run up toward Mount Elgon. The high, cool elevation slows the cherries maturation and concentrates the natural sugars.

Varietal

SL-14 and SL-28, selections best known from Kenya and grown here in Uganda. SL-28 in particular is prized for structure and dark fruit profile. Dried as a natural, the two lean towards deep and rich plum forward cup.

Processing

Natural. The whole cherries dry with the fruit intact, and the long contact between seed and pulp builds the dark plum notes and grape-cordial sweetness. It is the natural process doing the heavy lifting here, pushing a clean origin toward its darker, fruitier end.

Intervention level

Low. A straight natural process, no extra controlled processing steps, with careful drying rather than any manipulation shaping the final profile.

NOTES IN THE CUP

Dark plum opens the stage, ripe and jammy, closer to stewed fruit than fresh ones. Grape cordial follows, sweet and concentrated, the syrupy end of grape rather than the fresh one. Cacao sits at the finish, semi-bitter and dark, keeping the sweetness from becoming too intense. The body is smooth and full. As filter the plum spreads and the cacao lengthens the finish; as espresso it turns rich and syrupy, and it holds up well through milk. A dark, dessert-leaning cup with low acidity.

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.
