Tosba Espadin Mezcal, distilled from ten-year-old Agave angustifolia plants, is celebrated for its unique and delightful sensory profile. It presents a light nose, accompanied by a smooth, lasting citrus and fruitiness on the palate. A distinctive feature of this mezcal is the subtle smokiness derived from the wood-fired roasting of agave hearts, which adds depth to its flavor. This smokiness does not overpower the mezcal but rather complements its tropical character.

The mezcal varies slightly between batches, with the alcohol by volume (ABV) ranging from 42% to 48%. This variation contributes to its diverse tasting notes, which have been described by enthusiasts as ranging from sweet citrus and brown sugar to more complex flavors like butterscotch, medjool dates, and peppery notes. Some batches are noted for their deep, rich sweetness and others for a more balanced, lightly sweet profile.

Tosba Espadin Mezcal is double distilled using traditional wood-fired copper pot stills. The agaves used for this mezcal grow in a rich environment, alongside coffee, mango, pineapple, and banana trees, adding to its unique taste profile. The sweet and pure water used in the process comes from natural springs beneath the mountains, further influencing the mezcal's flavor.

The founders of Tosba Mezcal, two cousins from San Cristobal Lachirioag, Oaxaca, started the brand with a vision of reviving traditional mezcal production methods. Their journey began in 2000 when they migrated to Silicon Valley, California. Their commitment to traditional and sustainable mezcal production reflects in the quality and character of Tosba Espadin Mezcal, making it an excellent choice for both neat sipping and as a base in cocktails like a Mezcal Negroni​
