Plum Butter

JuicyRound

Plum Butter is a natural from Bulambuli in East Uganda, produced with our long-time partners at Ibero. It’s a profile we don’t come across often from Uganda: deep, smooth and fruit-forward, with dark plum, grape cordial and cacao. Rich without becoming too heavy.

FROM ORIGIN TO CUP

Plum Butter comes from Bulambuli in Eastern Uganda, where Ibero works with 200 to 400 smallholder farmers around Mount Elgon. Most farm less than one hectare, growing varieties including SL-14 and SL-28 at high elevation. For this natural, the cherries are carefully sorted before being taken to the drying yard, where the drying and fermentation are managed on tables. The cup is deep and smooth, with dark plum, grape cordial and cacao.

Origin

Bulambuli sits in Eastern Uganda around Mount Elgon, where Ibero works with 200 to 400 smallholder farmers. Most farms are smaller than one hectare and organised around local communities. We’ve been working with Ibero for years, and they opened the Bulambuli Washing Station in 2022.

Varietal

SL-14 and SL-28, two of the varieties commonly grown around Bulambuli alongside SL-34. These selections are also widely associated with neighbouring Kenya. In Plum Butter, we find a deep, fruit-forward cup with dark plum, grape cordial and cacao.

Processing

Natural. The cherries are carefully selected before being taken to the drying yard, where they ferment and dry whole on tables. The layers of coffee are adjusted throughout the process depending on the preparation and fermentation, with a specialised team managing the drying.

Intervention level

Low. This is a traditional natural process without additional controlled fermentation stages or added ingredients. The work is focused on cherry selection and careful management of the coffee throughout fermentation and drying.

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.
