Updated June 2026.
Sealed high-proof brandy does not spoil like leftover chicken. Official US brandy is bottled at not less than 40% ABV (27 CFR 5.145 this fetch). Quality can fade after opening because of oxidation and air in the neck. That is not a USDA leftover clock. This page will not invent opened-month numbers. Typical class brandy is 40% — read the neck, not a SKU we invented.
Sister leftover store/shelf 2026: does bourbon go bad, does vodka evaporate, how long vodka lasts, whiskey unopened, how to store bourbon, how to store whiskey at home. Cognac-class sister (do not recat this slug): how long cognac lasts.
What brandy is on the label
27 CFR 5.145(a) this fetch: brandy is spirits distilled from the fermented juice, mash, or wine of fruit, or from the residue thereof, distilled at less than 95 percent alcohol by volume (190 proof), with the taste, aroma, and characteristics generally attributed to the product, and bottled at not less than 40 percent alcohol by volume (80 proof). “Brandy” without a fruit qualifier is grape brandy. Cognac is a delimited grape-brandy type under the same section — leftover cognac pages already hold that line. This slug stays brandy (cat 12), not a cognac crown (cat 13).
The 2022 URL’s “35 to 60 percent versus wine at 11.6 percent” band is unused as a class lock. The federal floor for the class is 40%. A flavored brandy drink or a liqueur that mentions brandy on the neck can sit in another class. Read the class line. We will not invent a Hennessy, E&J, or Christian Brothers SKU ABV this run.
| Situation | What is true | What is not a clock |
|---|---|---|
| Sealed, unflavored class brandy ≥40% | Does not spoil like milk; high-ABV spirit | A USDA leftover day-count |
| Opened, recapped, cool and dark | Oxidation can flatten aroma as headspace grows | Official “6–8 months” (2022 URL — unused) |
| Hot car, sun, attic | Heat and UV speed chemical change; seals can fail | A second barrel-age year in glass |
| Cream / fruit / low-proof SKU | A different bottle than class brandy | Treating it like sealed 80 proof |
| USDA/FSIS 2-hour rule | Perishable cooked leftovers at room temp | A sealed-spirit statute |
USDA leftovers are not a brandy statute
FSIS leftover guidance (Leftovers and Food Safety; Keep Food Safe basics) this search: perishable leftovers must be refrigerated within two hours (one hour if the air is above 90°F). Cooked fridge leftovers are a 3–4 day quality-and-safety window. That chart is chicken, casseroles, and deli meat. It is not a 750 mL of 40% grape brandy. Packaged class brandy is a poor home for the bacteria leftover charts worry about. A swollen, leaking, or clearly contaminated bottle is a discard. A six-year-old sealed brandy that tastes a little tired is a disappointment, not a USDA leftover case.
Official open-bottle month counts were unused this run. The 2022 “finish it in six to eight months” line is folklore, the same unused clock leftover bourbon and vodka pages already refused. TTB does not publish a consumer month timer on 5.145. Keep the cap on. Store it upright, cool, and dark. That is enough.
What actually changes the pour
Oxidation is air plus time in the neck. Evaporation is ethanol leaving a loose pour spout. Neither is a stopwatch we will invent. A half-empty fifth with a leaky cork has more headspace than a full, capped 750 mL. Recap it. Glass does not keep aging the spirit the way a barrel did — leftover whiskey/bourbon store pages already say TTB age is oak time before bottling (27 CFR 5.74). Brandy in the bottle is the same idea.
Infusing a tired bottle with vanilla or dried fruit is a kitchen project, not a food-safety rescue and not a ranking. Refrigeration is a texture choice, not a brandy statute. A home freezer will not “preserve” 80-proof the way it preserves leftovers. Do not treat the FSIS 2-hour rule as a neat-pour timer.
