Grappa 101: from pomace to bottle
Quick answer
Grappa is an Italian geographical indication (IG) protecting a production method rather than a place: it must be distilled exclusively from vinacce — the skins, seeds and stems left over after winemaking — grown and vinified entirely in Italy, with a minimum alcohol content of 37.5% by volume and a capped methanol content. Unlike every other denomination in this atlas, Grappa has no defined production zone: it can legally be made anywhere in the country, as long as the raw material and process rules are respected.
Made from pomace, not grapes
Grappa is a pomace brandy: it's distilled from vinacce, the solid leftovers of winemaking — skins, seeds, sometimes stems — rather than from wine itself, which is what separates it from a grape brandy like French marc's Italian cousins in name only. The pomace can be fermented or semi-fermented before distillation, depending on whether it comes from red or white winemaking.
Why it has no region
Every other denomination in this atlas is tied to a specific zone — a town, a set of comuni, a province. Grappa is the exception: its disciplinare protects the raw material and the process, not a place, so it can be legally distilled anywhere in Italy as long as the pomace itself came from grapes grown and vinified in Italy.
The rules that do apply
What the disciplinare does fix precisely: a minimum alcohol content of 37.5% by volume, a maximum methanol content of 1000 grams per hectolitre of pure alcohol, and — non-negotiably — that the source pomace must come exclusively from grapes both grown and vinified on Italian soil. Foreign pomace, however it's distilled, cannot legally be called Grappa.
From pomace to bottle
After pressing for wine, the leftover pomace still holds alcohol, aromatic compounds and water. Distillers heat it in a still — traditionally a bain-marie or direct-flame copper still — to separate and concentrate the alcohol, then cut the resulting spirit to bottling strength with water. Some Grappa is bottled clear immediately after distillation; some is aged in wood for a period the producer chooses, since ageing isn't dictated by the disciplinare itself.
A geographic indication without a place
The "geographic" in Grappa's Indicazione Geografica refers to Italy as a whole, not a sub-region — it protects the fact that the raw material was grown and processed within Italian borders and that the production method follows the rules above, rather than guaranteeing a specific terroir the way a wine DOCG does.

FAQ
Does Grappa have to come from a specific region of Italy?
No — it's the only IG in this atlas with no defined production zone. It can legally be distilled anywhere in Italy.
What is Grappa actually made from?
Vinacce — the pomace (skins, seeds, sometimes stems) left over after pressing grapes for wine — not from wine itself.
What's the minimum alcohol content?
37.5% by volume, with a maximum methanol content of 1000 g/hl of pure alcohol.
Is Grappa the same as brandy?
No — brandy is distilled from wine (or grapes directly), while Grappa is distilled from pomace, the solid leftovers of winemaking. Different raw material, different spirit.
Why is it called a "geographic indication" if it has no zone?
Because it protects that the pomace came from grapes grown and vinified in Italy and that production followed the disciplinare's rules — not a specific micro-zone.
