Mezcal, often compared to tequila, is a unique agave-based spirit with a distinct smoky flavor. While both mezcal and tequila originate from Mexico, their production processes differ significantly. Mezcal Tequila is made using both traditional and modern methods, each impacting its taste, texture, and complexity. This guide explores these production techniques step by step, highlighting the differences between age-old practices and contemporary innovations.
Step 1: Harvesting the Agave
Mezcal is made from over 30 species of agave, while tequila is exclusively derived from the blue agave plant. Traditional mezcal production begins with harvesting mature agave plants, typically between 7 to 15 years old. The plant's heart, or piña, is cut out and transported for roasting. In modern methods, mechanized tools like tractors and specialized blades make harvesting more efficient compared to the traditional use of machetes.
Step 2: Cooking the Agave
The most defining step in mezcal production is how the agave is cooked. Traditional mezcal is roasted in underground earthen pits lined with volcanic rocks. These pits are heated with burning wood and covered with soil, allowing the piñas to slow-cook for several days. This process infuses mezcal with its signature smoky flavor.
Modern production often replaces underground roasting with autoclaves or stainless steel ovens, similar to tequila production. This method speeds up the cooking process and reduces the smoky notes, creating a smoother and lighter mezcal. Some producers combine both techniques to balance efficiency and flavor authenticity.
Step 3: Crushing the Cooked Agave
Once the agave is cooked, it needs to be crushed to extract the fermentable sugars. Traditional mezcaleros use a tahona, a large stone wheel pulled by a mule or horse, to crush the agave. This slow, labor-intensive process helps retain more fiber and enhances the complexity of flavors.
Modern mezcal production often employs mechanical shredders, which process the agave much faster. While this method improves efficiency, it can slightly alter the texture and taste of the final product. Some distillers choose hybrid approaches to maintain quality while increasing production capacity.
Step 4: Fermentation
Traditional mezcal is fermented in open-air wooden or earthenware vats using wild yeast. This natural fermentation process can take up to a week or more, depending on environmental conditions. Wild yeast adds unique flavors to each batch, making traditional mezcal highly variable in taste.
Modern techniques use stainless steel tanks with controlled yeast cultures, ensuring consistency across batches. While this process standardizes flavor, it can reduce the artisanal complexity found in traditionally fermented mezcal.
Step 5: Distillation
Distillation purifies the alcohol and concentrates flavors. Traditional mezcal is distilled in small copper or clay pot stills, usually twice, to achieve the desired alcohol content. The use of clay stills, common in regions like Oaxaca, imparts an earthy minerality to the mezcal.
Modern distilleries use larger copper stills or stainless steel columns for more efficient production. While these methods enhance consistency and scalability, they may not capture the nuanced flavors developed in traditional pot stills. Some producers experiment with blending both distillation methods to create a balanced product.
Step 6: Aging and Bottling
Mezcal can be consumed straight from the still as joven (young) or aged in barrels to develop deeper flavors. Traditional mezcal producers may store the spirit in glass containers, clay pots, or wooden barrels. Modern-aged mezcal follows a similar aging process to tequila, using American or French oak barrels to create reposado (aged 2–12 months) and añejo (aged over a year) varieties.
Bottling follows strict regulations to ensure authenticity. Traditional mezcal often features hand-labeled bottles with artisanal packaging, while modern producers use automated bottling lines for efficiency.
Conclusion
Traditional and modern mezcal production methods each have their advantages. Traditional techniques preserve the authenticity, depth, and regional uniqueness of mezcal, while modern innovations improve efficiency and consistency. Whether made the old-fashioned way or with contemporary methods, mezcal remains a fascinating and complex spirit distinct from tequila. As more consumers explore aged varieties, añejo tequila continues to gain popularity alongside high-quality aged mezcal.
