Grappa is an Italian pomace brandy, which is produced by distilling the leftover skins, stems, seeds, and pulp of grapes (known as pomace) after they have been pressed for winemaking or other purposes.
Similar to wines, the flavor of grappa depends on the types and quality of grapes used, as well as the specifics of the distillation process. Traditionally, most grappas are unaged and therefore clear or lightly colored from the original pomace. However, there is a recent trend of barrel-aging grappas, resulting in colors ranging from pale yellow to reddish brown. Grappa is typically enjoyed as an after-dinner drink or digestif, but it is also sometimes added to coffee, known as “caffè corretto” (“corrected coffee”).
“Grappa” is a protected name in the European Union, and for a product to be legally labeled as “grappa,” it must meet certain criteria. It must be produced in Italy (or San Marino or the Italian part of Switzerland), made from pomace, and undergo fermentation and distillation without the addition of water. The third criterion is what distinguishes grappa production. Since distillation must occur on solid matter, a steam process is used to prevent the pomace from burning. Additionally, because the woody components of the pomace (stems and seeds) must ferment with the sugar-rich juice in the skins, a small amount of methanol, which is more toxic than ethanol, is produced. Therefore, it is crucial to remove this toxic methanol during the distillation process. Italian law requires winemakers to sell their pomace to grappa producers to ensure the production of a safe and palatable product.

Distillation is an ancient process that can be traced back to the 1st century C.E. However, the distillation of alcoholic beverages specifically dates back to the 8th century in Levant and Persian cultures, with the technology likely spreading to Europe during the Crusades. By the 12th century, the School of Salerno in Italy was conducting reliable distillation. Around 1300-1400, water was introduced as a coolant in the distillation process. In the 1600s, the Jesuits of Spain, Italy, and Germany studied and documented brandy/grappa production techniques, which remained in use until the 20th century. Modernization in grappa distillation occurred in the late 1970s with the introduction of steam distillation (bain-marie), improving upon the older and sometimes problematic direct-heat method of distilling solid pomace.
In addition to advancements in distillation, modern grappa production has also focused on enhancing flavor. Today, there are many boutique grappas available, and the glassware used to enjoy grappa has become more sophisticated. Traditionally, grappa was consumed in shot glasses, but now it is often served in small, stemmed, tulip-inspired glasses.
Pomace brandy is not exclusive to Italy. Other countries have similar liquors with different names, such as “aragh” in Persia (Iran), “orujo” in Spain, “marc” in France, “chacha” in Georgia, and “rakia” or “rakija” in Albania, Bosnia, Croatia, Montenegro, and Serbia. Portugal has “bagaceira,” and Greece has “tsipouro,” among others.
