Ethiopia Buku Natural
ETHIOPIA
BUKU NATURAL
TROPICAL SMOOTHIE, CHAI SPICE, MANGO, PAPAYA, DENSE BERRY
The cup explodes with fleshy mango and ripe papaya—like a tropical smoothie—before moving into dense berry sweetness, Madagascar chocolate, and warm baking spices reminiscent of chai, cinnamon, and star anise. The finish is exceptionally sweet and seems to last forever.
Buku Naturals have become a Color favorite for a reason.
BEAN DETAILS:
ORIGIN: Buku Abel, Guji, Ethiopia
ELEVATION: 2,100–2,300 masl
VARIETY: Heirlooms
PROCESS: Once cherries arrive at the station, they are placed in water for sorting and removing floaters. For the washed lot, cherries are then depulped, dry-fermented for 96 hours, and washed to remove the mucilage. The parchment is then laid out to dry on raised beds for 12-14 days.
TASTING NOTES: palisade peach, drippy ripe melon, pluot, sparkling
ROAST TYPE: Light
Farm Level
About the Coffee
This lot comes from smallholder producers in Buku Abel, located in Ethiopia's Guji Zone at elevations between 2,100 and 2,300 meters above sea level.
The Guji Oromo people have cultivated coffee across these highlands for generations. While Guji shares Ethiopia's famous floral character, the region has developed its own identity—producing coffees that are deeply aromatic, juicy, and fruit-driven while maintaining remarkable elegance.
This season marks our first purchase from this family-owned washing station, although we've visited them on previous trips to Ethiopia. After cupping through dozens of offerings, Buku Abel stood out immediately as one of the most expressive coffees on the table.
The Process
Quality here begins with obsessive sorting.
Upon delivery, freshly harvested cherries are floated in water to remove underripe fruit before being hand sorted once again. The cherries are then dried whole on raised beds for two to three weeks, during which workers continuously turn and sort the coffee by hand.
That relentless attention to detail is what separates great Ethiopian naturals from merely good ones.
Removing underripe cherries at every stage creates a remarkably uniform fermentation, allowing the coffee's fruit to shine without becoming heavy or boozy.
The result is everything we love about a classic Guji natural—vivid fruit, sparkling aromatics, and incredible sweetness wrapped in a beautifully clean cup.

Brew Guide
Filter & Espresso
You bought great coffee. Brew it that way. Below is how we approach extraction at Color — built from years of roasting, tasting, and a lot of dialing in on our favorite brewers: Hoop, Pulsar, UFO, and Origami Air.
Brew how you’d like — but if you want it how we taste it, start here.
REST
Great coffee changes over time. Don’t rush it.
Filter:
→ 2–6 weeks off roast
→ Sweet spot: 3.5–6 weeks
This is where things get cleaner, riper, and more clear. Fruit tones deepen. Structure gets polished and the finish cleans up.
Espresso:
→ 4–6 weeks off roast
You can pull earlier. It’ll be brighter and aromatic. Around week 4, it rounds out and gains density.
If you enjoy tasting evolution like me, just keep brewing and wait for it to get better!
WATER
Water matters more than most variables. We QC with TWW at full strength, the light roast profile, but these coffees truly sparkle with most soft water profiles. Most mountain water is hard so be sure to adjust accordingly. Definitely filter out chlorine and sulfur if using tap water. Apex is making some really cool water drops!
Ideal Range:
→ 30–80 ppm
→ Moderate alkalinity
→ Balanced calcium/magnesium
Softer water increases clarity and perceived sweetness. Harder water can flatten acidity and mute top notes as well as muddy the finish.
FILTER BREWING
Core Philosophy
- Even extraction > aggressive agitation
- Minimize channeling
- Control flow rate
- Your taste is the most important factor!
- Bed Depth is critical, check out Jonathan Gagne’s thoughts on this
We aim for:
- Extraction Yield: 20–23%
- TDS: 1.35–1.55
- Clean, structured sweetness
- The least amount of astringency possible
- No hollow center, flat beds
RATIO
We cup at 1:17
For brewing, we gravitate toward:
- 1:16 – 1:17
- Personal favorite: 1:16.75
- If the coffee is ultra-dense or fruit-forward, push toward 1:17. If you want more saturation and body, lean toward 1:16.
GRIND
Medium-fine for most flat-bottom / hybrid brewers.
You should see:
- Even drawdown
- No stalling
- No rushing
- See Jonathan Gagne’s bed depth post
If it tastes:
- Sour → grind finer or reduce chanelling
- Bitter/astringent/dry → grind coarser
- Thin → increase extraction (finer or hotter water)
BREWERS WE LOVE
Hoop
Low agitation. High clarity. One pour.
Let gravity do the work. Make sure to break the crust when you finish pouring.
Use a metal aeropress filter if you’re struggling with choking and/or slow draw downs.
Pulsar
Excellent for brewing for 2 people.
Aim for doses 25g - 30g to reduce channeling risk.
Bloom with the valve closed. Open after the first pour.
UFO
Expressive, modern clarity.
Great for highlighting fruit structure. Forgiving.
We love the sibarist filters.
Origami Air
Run conical filters for clarity, flat-bottom for structure.
Control your pour pattern — even spirals, minimal disturbance.
Thermally stable, easy pour over option.
POUR OVER POUR STRUCTURE (General Framework)
For a 1:16–1:17 brew:
- Bloom: 2–3x coffee weight (45–60g for 21.5g dose)
- 60 sec bloom
- 2–3 controlled center-out pours
- Avoid heavy swirling or stirring
- Let it draw down naturally with a light rattle after the last pour. Agitation increases extraction — use it intentionally.
ESPRESSO
Rest longer. Be patient.
Starting Parameters:
- 1:2 – 1:2.5 ratio
- 25–35 sec
- 93–95°C
- Adjust based on roast level and density
These coffees often open up at slightly higher extraction. Don’t be afraid of longer shots if they remain sweet and structured. More shot volume = more extraction.
You’re looking for:
- Dense sweetness
- No harsh finish
- Lingering fruit or chocolate clarity
- Structured acidity, not sharpness
If it’s thin → grind finer or increase ratio
If it’s harsh → coarsen or lower temp slightly
WHAT WE’RE TASTING AT OPTIMAL EXTRACTION
- Saturated sweetness
- Clear fruit articulation
- No hollow mid-palate
- Weight without heaviness
- Long finish
When you hit it right, it feels polished. Not loud. Not dull. Just complete.
FINAL NOTES
- Rest matters.
- Water matters more.
- Extraction is measurable.
- But taste is king.
Brew whenever you’d like. Track changes. Stay curious.
If you dial something incredible on your Hoop, Pulsar, UFO, or Origami Air — tell us.
We’re always chasing better coffee.

Coffee Faq
IS YOUR COFFEE ORGANIC OR FAIR TRADE?
In many cases, yes. However, our first priority is quality and flavor. Sometimes these priorities align and our producers are certified organic and/or fair trade. We always pay well above fair trade rates (which are quite low and don’t guarantee sustainability or quality).
Often times, the producers we work with are too small to gain certifications. It’s expensive and laborious. Many of our producers are certified organic and fair trade, including many of our producers in Peru, Ethiopia, and Mexico.
WHAT IS THE BEST TIME-FRAME TO DRINK MY COFFEE?
We recommend drinking our coffee within one month of the roast date. Most of our coffees taste best however within 2 - 14 days of roast date.
For espresso, we recommend using coffee that has rested at least 7 days after roast date. This is because coffee gives off CO2 after roasting that can interfere with extraction. One way to get around this is to let your ground espresso dose sit for 30-120 minutes before pulling the shot. Email info@colorroasters.com for more questions about this.
If you are pre-grinding the coffee, we recommend drinking the coffee within one week of grinding.
CAN YOU GRIND MY COFFEE ON WEB ORDERS?
Yes, we can. Please select how you want your coffee to be ground at the time you place your order. Simply click on the arrow beside "Grind" and make your selection. If you need help choosing let us know the brewing method you will be using to prepare the coffee, in the notes of the order. And we will be happy to grind the coffee for you on our commercial grinder.
DO YOU HAVE BREW RECIPES?
These are in the works! We are compiling a bunch and even shooting some video, to help you brew like us at home.
