Costa Rica Starmaya AAP2025

Not sure how much coffee you need?

1 cup of coffee = a 240 ml serving based on a 1:16 brew ratio

For example, if your brew ratio is 1 to 16 (often expressed 1:16, or 1/16), then for every one part coffee, you use 16 parts water. In other words, to prepare 1 cup of brewed coffee you would use 15g of ground coffee and 240 ml of water.

May we present: the 2025 Austrian AeroPress Competiton Coffee for Round 1. 

Harvest and processing of Las Lajas Black Diamond coffees is supervised with great care by Oscar and Francisca Chacón. During harvest, Francisca measures the Brix value of the cherries to determine the optimal degree of ripeness, and harvesting begins when the Brix value is about 22°. Harvesting by Brix measurement is also helpful because newer varieties sometimes ripen to different colors: using a refractometer helps keep the crop at a consistent level of ripeness which is critical in the production of high-quality naturals and honeys. 

This microlot is prepared with care and love by the whole family. Las Lajas Black Diamond coffees are harvested very late and carefully checked for defects by hand and washed under fresh spring water. It is then dried in the sun for about 7 days. Then fermented for another 30 days on special temperature-controlled, shaded beds using the "black diamond" process. When a water content of 11% is reached in the beans, an in-house procedure of repeated heating and cooling leads to the crowning conclusion. This process is very labor-intensive and results in unique aromas.

We source this coffee through our friend Peter Scheiber from el.kaffee.

Starmaya is a new and rare arabica variety. We received 30kg of it - which means it is strictly limited. We have a total of 40 bags of 250g available - the rest is reserved for our AeroPress Championship competitors who will receive it on the day of the competition, Saturday 27th of September.

Find here information on Starmaya as given by World Coffee Research:

A first-generation (F1) hybrid originating from a cross between Marsellesa and a male-sterile Ethiopian or Sudanese landrace variety. F1 hybrid varieties are still relatively new in coffee agriculture; only a handful have become commercially available to farmers in the last 15 years, and only in select countries. So far, Starmaya is the only F1 hybrid in the world that professional seed producers can propagate by seed, rather than through costly biotechnology. Before Starmaya, the only way to efficiently reproduce F1 hybrids for farmers has been through cloning (tissue culture cloning/somatic embryogenesis) or manual pollination of the mother and father plants, both of which methods are costly and have limited capacity. As early as 1998, coffee breeders recognized that it would be theoretically possible to propagate F1 hybrids via seed if one of the parent plants were sterile. If you place two different fertile coffee varieties—your desired hybrid Mother and Father varieties—together in a typical field of coffee, some offspring would be the result of Mother to Mother crossing (resulting in offspring that look like the Mother), some Father to Father (offspring like the Father), and only some would be Mother to Father (offspring hybrids of the two). This is obviously an inefficient way to produce hybrid seed. However, if one of the varieties in the field is sterile (meaning it does not produce pollen), then any offspring (e.g., coffee cherries, the product of sexual reproduction of the Mother and Father) that appear on male sterile plants must be hybrids between Mother x Father. Wind or pollinators would carry the pollen from the pollen-producing variety onto the sterile variety, and the resulting cherries would necessarily be hybrids. The challenge was to find a naturally male sterile plant that could be a suitable breeding parent. In 2001, researchers from Centre de coopération internationale en recherche agronomique pour le développement (CIRAD) collaborating in a public-private coffee breeding project with ECOM, noticed a male-sterile Arabica plant growing in a population of wild Ethiopian and Sudanese coffees on the La Cumplida farm in Nicaragua. Breeders crossed it with Marsellesa, a newer-generation rust-resistant variety (Timor Hybrid 832/2 x Villa Sarchi CIFC 971/10). After observing good performance in field trials in Nicaragua, ECOM released the variety, naming it Starmaya.

Did you read all that? Wow, you should really sign up for the AeroPress Competition.
