A Quick Guide to Grappa
Grappa is a true gem of Italian heritage, embodying an alchemical transformation where grape skin and pulp are distilled into a potent and flavorful spirit. Only a select few producers have mastered the art of creating exceptional, mind-blowing grappas. This incredible journey, known as distillation, starts with the fermented grape skin leftover from winemaking.
How Grappa is Made
The process begins with grape harvest. The grapes are sent to the winery to be destemmed and crushed, then placed into large tanks where the magic of fermentation occurs. During fermentation, yeasts convert the natural sugars in the grapes into alcohol.
Once fermentation is complete, the liquid (wine) and solid parts (grape skins and pulp) separate. While the wine continues its journey to become the beloved nectar we all enjoy, the leftover crushed grapes, known as vinaccia (or pomace), embark on a unique path to becoming grappa.
Fresh vinaccia is sent to the distillery and can be:
- Fermented if it comes from red grapes that have undergone maceration.
- Non-fermented (virgin) if it comes from producing white wine. In this case, the marc must be fermented before distillation as alcohol is necessary for the process.
The Distillation Process
There are two main types of distillation:
- Discontinuous-cycle: Used for high-quality, artisanal grappa.
- Continuous-cycle: Used for industrial mass production.
We’re all about the discontinuous-cycle, the method that creates the good stuff! The fermented marc is placed in copper stills, which are then sealed and heated using direct fire, bain-marie, or steam. The volatile components separate based on their boiling points, extracting alcohol and aromatic substances.
The Magic of Grappa
The vapors are cooled back into liquid form. The first part of the distilled liquid, known as the “head,” is eliminated because it contains unpleasant flavors and toxic methyl alcohol. The “heart” of the distillation, where all the wonderful aromas reside, is collected next. The “tail,” which contains fats and oils, is also discarded as it would spoil the final product.
The Master Distiller is the magician who recognizes and selects the heart of the distillate, controlling the vapors and aromas to craft a harmonious grappa. This process is done manually, requiring great skill and intuition.
After distillation, the grappa-to-be has an alcohol content of 65-85% alc/vol, which is far too strong to drink. The alcohol content is reduced by adding distilled or mineralized water. By law, the final alcohol content must range between 37.5% and 60% alc/vol, depending on the style the producer aims to achieve.
