Definition
San Ramon is a dwarf mutation of Typica discovered in Costa Rica that resists wind damage and produces a clean, sweet cup.
Why It Matters
A common misconception is that all dwarf coffee varieties are high-yielding. While San Ramon's compact size allows for higher planting density, the individual plants are known for relatively low cherry production compared to other dwarf mutations like Caturra [San Ramon Coffee Variety: A Costa Rican Coffee](https://www.homegrounds.co/san-ramon-coffee/). Additionally, there is frequent confusion between the Costa Rican San Ramon and the Guatemalan 'Pache San Ramon'; while both are dwarf Typica mutations, they emerged in different geographical contexts [specialty coffee wiki](https://www.moduscoffee.com/specialty-coffee-wiki/). Another misconception involves its disease resistance; while valued for its hardiness against wind and drought, its level of resistance to coffee leaf rust can vary significantly depending on the specific environment and local strains of the fungus [Glossary San Ramon | XLIII Coffee](https://xliiicoffee.com/en/glossary/san-amon/).

Related Concepts
Acidity
In coffee tasting, acidity refers to the bright, vibrant, and often fruity quality that gives coffee its liveliness and structure. Unlike the negative connotation of acidity in everyday language, coffee acidity is a desirable characteristic when balanced. It is perceived as a pleasant tartness or brightness on the palate, similar to the acidity in wine or fruit.
Varietals & CultivarsBatian Coffee Variety
Batian is a modern Kenyan release from the Coffee Research Institute, bred for disease resistance while preserving the cup quality of SL28 and SL34. Named after Mount Kenya's peak, it delivers bright acidity and blackcurrant notes at altitudes above 1,700 meters.
Sensory & TastingBody
Body, also called mouthfeel, refers to the physical weight, texture, and viscosity of coffee as it is perceived in the mouth. It is a tactile sensation rather than a taste, ranging from thin and tea-like to thick and syrupy. Body is influenced by brewing method, coffee oils, suspended solids, roast level, and the variety and origin of the coffee.
Varietals & CultivarsBourbon Coffee Variety
Bourbon is one of the two foundational arabica varieties, named after Réunion Island (formerly Île Bourbon). It produces higher yields and a sweeter, more complex cup than Typica, with distinctive notes of chocolate, caramel, and red fruit that set the standard for specialty coffee quality.
Varietals & CultivarsCastillo Coffee Variety
Castillo is Colombia's most widely planted variety, bred by Cenicafé as a disease-resistant descendant of Catimor. Successive selections improved cup quality significantly, and well-grown Castillo from high-altitude farms in Caldas and Nariño delivers sweet, balanced cups that far exceed its reputation.
Varietals & CultivarsCatuai Coffee Variety
Catuai is a compact hybrid of Mundo Novo and Caturra bred in Campinas, Brazil. Its small stature enables high-density planting and easier harvesting, while its cup retains a clean, bright acidity with sweet citrus notes that perform well across Central and South American farms.
Coffee ScienceCoffee Leaf Rust
Hemileia vastatrix belongs to the order Pucciniales and is an obligate biotrophic fungus, meaning it requires living host tissue to survive. The infection cycle begins when urediniospores are deposited on the abaxial (underside) surface of the coffee leaf, typically via wind or rain splash. Germination occurs only in the presence of free water—such as dew or rainfall—within a temperature range of 15°C to 28°C. Upon germination, the fungus enters the leaf through the stomata and establishes a mycelium that colonizes the internal tissue. The visual manifestation of the disease begins as small, chlorotic spots that expand into characteristic orange, powdery pustules. These pustules contain thousands of spores capable of further infection. The physiological impact includes a rapid reduction in photosynthetic capacity and the eventual abscission of the leaf. Severe cases lead to 'dieback,' where the plant's branches wither due to carbohydrate depletion, often resulting in the death of the tree or a total loss of the following year's crop.
Sensory & TastingCupping
Cupping is the standardized professional method for evaluating coffee quality and flavor. Developed by the specialty coffee industry, cupping involves smelling and tasting coffee prepared through a controlled immersion method, then scoring specific attributes including fragrance, aroma, flavor, aftertaste, acidity, body, balance, uniformity, clean cup, sweetness, and overall impression.
Varietals & CultivarsEthiopian Landrace Coffee
Ethiopian landrace varieties are the wild and semi-wild arabicas of Guji, Yirgacheffe, and Sidama, each region hosting genetically distinct heirloom populations. This unmatched genetic diversity produces the floral, citrus, and berry-dominant cups that define Ethiopian specialty coffee.
Brewing MethodsGrind Size
Grind size refers to the particle size of ground coffee, which is one of the most critical variables in coffee brewing. Grind size ranges from very fine (powder-like, used for espresso and Turkish coffee) to very coarse (chunky, used for cold brew and French press). The grind size directly controls the rate of extraction by determining the total surface area of coffee exposed to water.
Coffee CultureSpecialty Coffee
The classification process necessitates precise environment control. During the grading phase, the coffee is roasted within 24 hours of cupping and allowed to rest for at least eight hours. The roast level must fall within the light to medium range, specifically between 55 and 65 on the Agtron scale. Cupping involves a standard ratio of 8.25 grams of coffee per 150 milliliters of water, with water temperatures maintained between 92.2°C and 94.4°C (198°F to 202°F). This protocol ensures that the inherent characteristics of the bean—such as the phosphoric acidity typical of Kenyan origins or the stone fruit notes of Colombian Caturra—are evaluated without the interference of roast-induced flavors.
Origins & GeographyTerroir
Terroir is the set of environmental factors that give coffee its unique character, including soil composition, altitude, climate, rainfall, microclimate, and topography. Borrowed from winemaking, the concept of terroir explains why coffees from different regions taste distinctly different.
