Does Gin Go Bad? Shelf Life of an Open Bottle
Quick Answer: The change Bulldog describes in gin is flavor, not spoilage. Its FAQ says its gin has no expiry date and that, once open, it can be drunk safely if stored cool and dry, away from direct sunlight and high temperatures. Over time it may lose some of its subtle flavor characteristics. Bulldog gives no number of months or years, and no other gin maker is cited here.
Gin is a short answer with one catch: the only sourced change is flavor, and nobody in this research puts a date on it. This guide covers what Bulldog says, how to store an open bottle and when a slow-moving gin is worth moving out of the well. For the spirits-wide picture, see does liquor expire, and for the storage rules, how to store liquor.
Does gin go bad after opening?
It can lose flavor, and Bulldog does not describe it as spoiling. Bulldog's FAQ (checked October 2026) says that, like other spirits, its gin does not have an expiry date, and that once a bottle is opened it can be drunk safely if stored in a cool, dry place away from direct sunlight and high temperature. It adds that over time the gin may start to lose some of its subtle flavor characteristics. That is one producer speaking about its own London Dry gin, so read it as a starting point for other gins, not a rule for them.

What fades first in an open bottle of gin?
Flavor, according to the only source here. Bulldog calls them subtle flavor characteristics and does not list them. Gin is flavored with botanicals, so a fading aroma is the likely meaning, but the page does not say that, so this post does not either. No gin maker's page read for this guide gives a rate, a fill level or a cutoff. If an old bottle smells or tastes flatter than you remember, it has drifted. Grey Goose says, for vodka, that if you are in doubt you should throw it out, and the same sense applies here.
How should you store an opened bottle of gin?
Cool, dry and out of direct sunlight and heat, which is Bulldog's storage line. On a back bar, that means not next to a window, a heat lamp or a hot appliance. Keep it closed between pours. Bacardi's FAQ (checked September 2026) says to keep rum tightly sealed so the flavor does not escape. That is about rum, but a closed bottle is a sensible habit for gin too. Write the open date on a bottle that sells slowly so you can judge it by how long it has been open.
When should gin come out of the well?
When it sells slowly. A well gin that empties in a shift is open only between pours. A bottle that lasts weeks is open the whole time, so it is the one to cap, label with the open date and keep away from the warmest part of the rail. No source sets a cutoff, so the decision is yours and rests on smell and taste. The dust caps post covers the bar-side case.
When is a pour spout cap the wrong choice?
When the bottle is going into storage for months. A cap over a pourer keeps dust and debris off the spout, but it is not the closure the bottle came with, and Bulldog's page does not mention pourers. For long storage, put the original cap back. See also the pour spout covers guide.
Where the Esatto 2-pack flip-lid pour spouts fit
Esatto makes and sells the 2-Pack Stainless Steel Liquor Pour Spouts with Flip Lids. It is our own product, not an independent pick. Its page says the built-in flip lid protects from dust and debris. A two-pack suits a home bar with a couple of gins in use. It is not a bottle stopper, so it is the wrong tool for long storage. You can also browse the lidded pourers and the pour spout covers.
