Our first foray into Bolivian waters has been met with beauty and intrigue.  We're excited to introduce the first coffee, Rosita Anaerobic Natural Caturra.  Donned with a fresh design from our friend and regular collaborator Tyler Kelly, we wanted to showcase another endangered animal from the region, The Andean Flamingo.  

Showcasing Bolivian flavors while offering complexity and juiciness from the fermentation style.  Flavors of red cherry and wine grape and hints of tropical fruits like lychee lead with a spiced finish that intrigues and leaves you guessing.

PRODUCER: Finca Rosita
PROCESS: Natural/Fermentation 4-5 days in an airtight containers/Drying 20-25 days on raised beds.
ELEVATION:  1350-1740 masl
TASTING NOTES: Red cherry and wine grape and hints of tropical fruits like lychee.

Farm Level
Finca Rosita is located in the Illimani community in the gorgeous region of Caranavi, Bolivia. The farm covers 32 hectares, solely dedicated to coffee cultivation. The farm is named in honor of the memory of the matriarch of the Valverde-Aramayo family, Rosa Angelica Aramayo. Depending on weather conditions, drying time varies from approximately 20 to 25 days. The fermentation is anaerobic, that means that the coffee is fermented in completely sealed tanks without oxygen. Airlocks are used to allow the coffee to release co2 gases without oxygen entering the tank. This allows a completely controlled and homogeneous fermentation. This lot is fermented and dried in cherry. To determine the proper fermentation point, a brix meter (sugar content meter) is used. During the fermentation process, the coffee releases a liquid that accumulates at the bottom of the tank. Each tank has a tap where the brix of the liquid is measured every 3 to 4 days to determine if the coffee has fermented properly. When the sugar content of the coffee reaches 8 brix, the coffee is removed from the tank to proceed with drying. This fermentation process takes between 4 to 5 days to complete. The community of Illimani is located near the base of the snow-capped mountain that also bears the Illimani name ("where the sun rises" in Aymara). With a height of 6,462 masl, this mountain is made up of 4 peaks and is the second highest mountain in the Bolivian Andes. The vegetation changes rapidly, from large plantations of potatoes and quinoa to many hectares of coffee, plantain, yucca and others. These and other peculiarities of the Andean terrain create the complexity and differentiation of the Bolivian coffee.

Brewing great coffee at home can be easy.  The essential tools are critical to making it happen.  They include:
  • Filtered water.  Spring water is ideal.  Removing chloride, sulfur, and iron is essential.
  • A burr grinder.  The more even the coffee particles, the better the coffee.  Burr grinders, whether manual or electric, will do a better job than "whirly-blade" grinders.  Invest in a burr grinder.  Your taste buds (and coffee roaster) will thank you.
  • A scale.  I know using a scale can seem a bit like you're doing something you shouldn't be.  Trust me, you can only brew consistently great coffee with a scale.  Water and coffee are hard to measure without one.
  • Clean equipment.  Properly cleaning your equipment is the only way to avoid stale and rancid coffee flavors entering your cup.  Please keep your equipment clean.  The sooner and more often you clean your gear, the easier it will be in the long run.  Add it to your ritual and thank us later.
  • Delicious and freshly roasted Color Coffee
Now that you have the tools, the rest is easy.  There are infinite numbers of ways to brew coffee.  Here are some of our favorites, with links to coffee professionals who we admire and trust:


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.


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 for more questions about this.

If you are pre-grinding the coffee, we recommend drinking the coffee within one week of grinding.


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.


These are in the works! We are compiling a bunch and even shooting some video, to help you brew like us at home.

A weak brew could the result of a couple things.  First of all, you want to make sure you're using the proper amount of water and coffee.  If you use too much water or not enough coffee, you won't be able to get the strength you need.  A digital scale will ensure you can get the measurements right.  Start with 1 gram of coffee to 16 grams of water and adjust to taste!
The second problem could be a grind size that is too course.  If the coffee bits are too big, you won't be able to pull enough flavor out and the brew will taste weak.  In general for drip coffee, the grind size should be the size of beach sand.  You can also use the brew time to help judge if you're grind is correct.  Most brewing methods should take between 3 and 5 minutes.  If it's going faster than this, it's likely your grind size isn't fine enough.  Grind finer and taste it!
