The roast level of coffee is entirely a personal preference. This preference is shaped especially by your palate, past experiences, and the region you live in.
First of all, let's state that coffee is a fruit, containing complex flavors and acidity. Despite this, during the roasting process, we can change this situation based on our preferences. The roasting process is a complex one.
Coffee goes through certain stages during roasting. The most important of these stages is the first crack stage, where the coffee becomes drinkable. At this stage, the moisture in the coffee evaporates, and the trapped steam creates pressure within the bean. The hard structure of the bean cannot withstand this pressure and expands, causing it to crack. A "cracking" sound is heard at this stage. The time elapsed after this sound determines the roast level of the coffee.
1. Light Roast
When the first crack begins, the roaster removes the coffee at a determined time and temperature without waiting for the popping to finish, and puts it to cool.
Light roast offers you the following:
· Flavor notes can be clearly perceived,
· Despite its light body, sweetness is abundant,
· It clearly reflects its regional character and terroir,
· It has a vibrant acidity.
Disadvantages: It is more prone to brewing errors. If the coffee is under-extracted or over-extracted, its taste will be sharp. If you don't have a quality coffee grinder, grinding can be difficult. If you are preparing espresso-based coffees, channeling risk is higher due to the hard structure of the beans, and acidity can become much more pronounced and disturbing. The gas release waiting period, which we call "degassing", is also longer compared to others. (Average 15 days)
2. Medium Roast
The most important difference between medium roast and light roast is that the coffee beans are removed after the first crack finishes.
Medium roast promises you the following:
· Flavor notes intensify and blend,
· It has low acidity,
· Its body (mouthfeel) is more intense.
· It is more balanced in Turkish coffee, espresso, and moka pot brewing methods,
· In high-pressure brewing methods like espresso, the risk of channeling is low. Brewing is easier,
· The gas release period is approximately 10 days.
· Automatic coffee machines with built-in grinders are not strained.
Disadvantages: Flavor notes and terroir characteristics are difficult to perceive. In filter coffee brewing, due to low acidity, it loses its vibrancy. Perceived sweetness is less compared to light roast. It reduces the potential of high-scoring specialty coffees.
3. Medium Dark Roast
While the roast profile is generally the same as medium, it is given a little more time for development.
Medium dark roast promises you the following:
· The coffee flavor is more intense,
· Only nuanced differences are felt between coffees,
· The mouthfeel is more intense compared to medium roast,
· Acidity is so low that it is barely felt in all brewing methods,
· If you are new to the world of espresso-based coffee, it is easier to prepare,
· It pairs very well with milky beverages; the coffee taste is more pronounced,
· The gas release period is approximately 7 days,
· It yields very successful results in entry-level coffee machines,
· More balanced coffees are prepared with low alkalinity household filtered water.
Disadvantages: The flavor notes are almost completely masked. In filter brewing, due to low acidity, the vibrancy of the coffee decreases. Perceived sweetness levels are lower compared to medium roast.
4. Dark Roast
Roasted longer than medium dark, the roasting is stopped immediately after the second crack is heard. The second crack is a structural crack. It follows the same logic as the crackling of burning wood on a fire.
Dark roast promises you the following:
· The classic coffee taste is at its most intense,
· Acidity is not felt,
· The difference between coffees is almost non-existent,
· Since coffee beans soften significantly, the gas release period is short,
· It is the preferred roast type by industrial producers due to the standardization it provides.
Disadvantages: Organic acids and complex aromatics are damaged. Therefore, regardless of the brewing method, bitter and harsh tastes are perceived. It stales quickly. In espresso, crema appears more abundant but its quality decreases. It covers up the flaws of coffee, making even low-quality coffee palatable.
Which Coffee Roast Should You Prefer?
Those who want to discover the flavor notes of coffee; understand regional and varietal differences, and consume a special filter coffee with natural acidity, should prefer a light roast. This roast is an excellent choice especially for those who want to explore the world of specialty coffee.
If you don't mind the flavor notes intensifying and blending, if you are looking for more full-bodied coffees, if you expect coffee to tolerate brewing errors, if you don't like pronounced acidity in filter coffee, and if you prefer a light acidity in espresso-based coffees, then medium roast is for you. Also, if you enjoy plain coffee and use an automatic coffee machine, a medium roast will satisfy you. In Rumo, you can find these coffees under the headings intense filter coffee and espresso.
If flavor notes are not important to you, and you are looking for a full-bodied coffee with low acidity and sufficient nuanced differences, then you should choose medium dark. This coffee is quite easy to brew in automatic coffee machines and entry-level espresso machines. If you love espresso but don't want bitter tastes, and you adore milky coffees, you should try medium dark coffees. In Rumo, Savanna Black perfectly meets these criteria.
If bitter, woody, and smoky flavors don't bother you, and you want an intense and oily mouthfeel along with a long aftertaste, you should try a dark roast. This is already used in industrial coffees. Therefore, it is a type of roast you will not find in Rumo.

ABOUT THE FARM;
This coffee comes from the Chirripó micro-region, which is part of the Brunca region in southern Costa Rica. The region gets its name from the local indigenous people, the Bruncas, who lived here before the arrival of the Spanish. Coffee cultivation began here at the end of the 19th century when the first settlers from the coffee-growing areas of the Central Valley moved to Brunca. However, the region was not integrated into the national coffee economy until the end of World War II.
The valleys between the mountains, rich volcanic soils irrigated by 3 rivers named el Chirripó, el General, and Grande de Térraba, provide ideal conditions for growing coffee. Coffee plantations are located between 600 and 1700 m.a.s.l. The climate is quite humid, with 3500 mm of rainfall, 85-100% relative humidity, and an average temperature of +22˚С.
The Chirripó micro-region is situated between two mountains: Cerro de la Muerte (3,491 m) and Cerro Chirripó (3,820 m, the highest in Costa Rica). The valley between these mountains has a unique microclimate that contributes to a remarkable cup. That is to say, coffee cultivation is on the rise here.
CAFÉ RIVENSE DEL CHIRRIPÓ
Mr. Régulo Gerardo Ureña has dedicated 35 years to coffee, a business he learned from his father. In the early 1990s, he bought his first farm, La Guaca. In 2005, with his wife Isabel and 4 sons, Mr. Régulo established his own micro-mill, Café Rivense del Chirripó. As one of the first coffee growers in their village, the Ureñas family regularly developed their farms to adapt to the changing demands of the specialty coffee market. They divided their plantations into smaller sections with different coffee plants, altitudes, and sunlight levels. This allows them to harvest different coffees each year. Their strong commitment to innovation and quality has resulted in numerous awards, including the prestigious Cup of Excellence and Good Food Awards. In 2019, one of their micro-lots placed 5th in COE, becoming the first farm from the Brunca region to enter the top 10. FINCA LAS TORRES is an 8-hectare farm sustainably managed to reduce carbon emissions. These include managing shade to provide natural material to the soil, keeping coffee trees healthy, using fertilizers based on soil tests, selectively using herbicides, protecting water sources from pollution, and planting fruit trees to support wildlife.

Aeropress standard method:
00:00 - 00:10 Fill with 200 gr water, stir back and forth 3 times and quickly close the plunger.
01:00 - 01:08 Remove the plunger, stir back and forth 3 times and close it.
01:08 - 01:30 Start pressing and complete brewing within 20-25 seconds.
French Press
Our first recommendation for those who ask what is the most practical and economical way to brew our coffees is the French press. It's not as clear as coffees brewed with a paper filter, but it's surprisingly successful.
