Primofiori Lemon

The Primofiori (also called Fino) lemon generally has a thinner, smoother rind than the Eureka and tends to produce more juice per fruit. Primofiori is the dominant Spanish commercial variety, whereas Eureka is more common in California and year-round markets. Both are acidic, but Primofiori fruit typically has very few seeds.

Fino and Mesero are older Spanish market names for the same variety that Primofiori now refers to in international trade. The names were used by growers in regions like Murcia and Valencia long before the Primofiori label became standard in export catalogs. All three names describe the same high-acidity, thin-peel Spanish lemon.

Primofiori lemons are grown mainly in the citrus-producing regions of southeastern Spain, particularly Murcia and Alicante. These areas benefit from a Mediterranean climate that produces high juice content and a smooth rind. Spain exports the variety widely across Europe during the autumn-to-spring harvest window.

Primofiori lemons are noted for containing very few seeds, often just a handful per fruit or none at all. This low seed count is one reason the variety is favored for commercial juicing and fresh retail. By contrast, older Spanish varieties like the Verna tend to carry slightly more seeds.
