Brewing: Kenya Boma AA

Welcome to our brewing series, this time sharing recipes for our newest arrival, Kenya Boma AA!

Our inspiration behind this series is to help our community either begin their journey into manual brewing methods, or act as a starting point for additional tweaking and calibration for those who are more seasoned.

Each post will include recipes for at least one of these three popular manual brewing devices (Chemex, V60, and Aeropress), and will include grind settings based on a Baratza Encore, a popular entry-level home burr grinder. We are excited to team up on this series with Alex Wallace (@wallacecoffee on Instagram), who will be contributing his personal recipes and findings with each coffee.

So without further ado, let's brew some Kenya Boma AA!

Kenya Boma AA

Region - Kericho County
Varietal - SL28, SL34
Process - Fully Washed
Elevation - 1700 - 2000 M
We Taste: lemongrass, cranberry juice, brown sugar

This coffee comes to us from Kericho County, located in western Kenya. 'Boma' is the name of the washing station in the area, where the cherries are brought and processed for export. There are 360 members of the washing station, of which 120 are women. The average member cultivates a couple hundred coffee trees on half-acre plots, intercropped with bananas, and macadamia trees. Coffee is dried for 14-17 days, then washed according to traditional processing.

All Kenyan coffee is graded, and sorted based on the size of the bean after processing. 'AA' is the designation assigned to the largest sized beans. Other designations include AB, C, and PB. While some regard AA as being a designation of the highest quality, this is only one of the many factors that contribute to great Kenyan coffee.

Kenyan coffees come with a very clean profile, often with complex brightness, and some great sweetness. That's exactly what this Boma AA delivers, showing off it's brightness with a nice floral aroma and a juicy body. When we cupped this coffee, our team tasted lemongrass, cranberry juice cocktail, and brown sugar.

Alex Says...

Atomic has been killing it with these coffees. This Kenya continues the legacy with a well balanced, complex cup. I decided to go two ways with this one with the AeroPress and the Hario V60. The brews were so similar but also had some different notes in the cup that I think allows people to enjoy this coffee more either way. On the AeroPress it brought in way more acidity with lemongrass and tart but sweet cranberry juice throughout the cup. It had a nice sweetness through it with a caramelized brown sugar in the finish and it was nice and silky.

On the Hario V60, I think it allowed more of a silky cup with way more sweetness, less acidity but still having that underlying acidity. The same notes came through just a little different. Heavier on the brown sugar sweetness, less on the cranberry juice. This brew also had a hint of milk chocolate coming through which I’ve never experienced with a Kenyan coffee.

Long story short, if you want more acidity go with the AeroPress. If you want more sweetness, the V60 is the way to go.


Hario V60 Recipe

Quick Facts

Method: Hario V60
Ratio:  20g coffee / 320g water
Grind: 16 setting on Baratza Encore
Water Temperature: 205F
Filter: standard Hario V60 filter

Brew
0:00 - 60g
0:45 - 190g
1:30 - 320g
Total Brew Time - 3:30

1. Boil - Start by filling up your kettle with water. If you have an electric kettle, set the temperature to 205F. If not, bring the water to a boil then let cool before brewing.

2. Grind - Weigh out 20g of coffee, and grind on your Baratza Encore at setting 16.

3. Pre-wet Filter - Place your V60 on top of the vessel you plan to brew into, and place a filter into the V60. Pour warm water over the filter, until you hit every spot. This avoids any papery tastes in your coffee. It also pre-warms the V60 and your brewing vessel, to avoid coffee cooling upon contact. This is also a good chance to pour warm water in your mug as well. Make sure to dump this water out before brewing.

4. Begin Brewing - Place your V60 / brewing vessel on top of your scale. Add your coffee to the filter. Make sure your scale is zeroed, and start your timer. Add 60g of water, then wait until your timer says 45 seconds.

5. Continue Brewing - At 45 seconds, continue pouring water until you reach 190g. Wait until your timer says 1:30, then pour until you reach 320g. Your total brew time, the point where you can take your V60 off the brewing vessel, should be about 3:30.

6. Enjoy! - Pour into your favorite pre-warmed mug, and enjoy!


Aeropress Recipe

Quick Facts

Method: AeroPress (Inverted)⁣
Ratio: 15g coffee / 240g water⁣
Grind: 16⁣ setting on Baratza Encore
Water Temperature: 205F
Filter: standard Aeropress filter

Brew
0:00 - 60g | stir 4x⁣
0:30 - 240g⁣ | stir 4x
1:00 - cap, flip, & slow press until 1:45⁣
Total Brew Time - 1:45

1. Boil - Start by filling up your kettle with water. If you have an electric kettle, set the temperature to 205F. If not, bring the water to a boil then let cool before brewing.

2. Grind - Weigh out 15g of coffee, and grind on your Baratza Encore at setting 16.

3. Add to Aeropress - Add your coffee to the Aeropress, on top of your scale. For the "inverted method", the piece with the plunger will be on the bottom, with the plunger facing upwards. Pop the other piece on top, then pour in your coffee (so coffee is sitting inside the top piece, and on top of the the "plunger". Make sure your coffee bed is evenly leveled.

4. Pre-wet Filter - Grab your filter, place it inside the cap, and pre-wet with warm water. This avoids any papery tastes in your coffee. This is also a good chance to pour some warm water in your mug, to avoid coffee cooling upon contact. Keep your filter and mug to the side for now.

5. Begin Brewing - Make sure your scale is zeroed, and start your timer. Add 60g of water, then stir four times to ensure all grounds are saturated. Wait until your timer says 30 seconds.

6. Continue Brewing - At 30 seconds, continue pouring water until you reach 240g. When your timer reaches 1:00, stir again, secure your filters and cap, flip the Aeropress over onto your favorite mug, and press down slowly. You'll know when you're done pressing when you hear the hissing sound - try to time it so that happens at 1:45.

7. Enjoy!
