Reading packaged-on and best before dates on beer in India

The dates you will see

Beer labels in India usually show a manufacturing or packing date and a best before date or period. Our guide to reading a beer label covers the rest of the label.

• Packed on, packaged on or date of manufacture. The date the beer was filled into the can, bottle or keg. This is the most useful date for judging freshness.
• Best before. Either a specific date, or a period such as "best before X months from manufacture". After this date the brewery no longer guarantees the beer will taste as intended.
• Batch number or code. A code that identifies the brew and filling run, used by the brewery to trace problems.

Labelling rules in India come from food safety regulations and state excise. They change over time. Requirements can also differ between states. If you are a producer, check the current regulations rather than copying another brand's label.

Where to find the date

On cans, the date is usually printed on the base or the shoulder near the rim, often in small dot-matrix print. On bottles, look at the neck, the back label or the shoulder of the glass. Some printers use a code rather than a plain date, such as a day number and year, which can take a little decoding.

If you cannot find a date, ask the shop or the taproom. A brewery that cares about freshness will be happy to tell you when the beer was packed.

What best before really means

A best before date is about quality, not safety. Beer after its best before date is usually safe to drink if the pack is sealed and undamaged, but it may not taste as the brewer intended. Hop aroma fades, flavours flatten and stale notes appear.

Different beers age differently. Our guide to beer shelf life covers this in detail. As a rough guide:

• Hoppy beers like IPAs and pale ales are best within a few weeks to a couple of months of packing. Our guide to fresh versus stale IPA shows the difference.
• Pale lagers and wheat beers are best fresh, within a few months.
• Strong, dark beers like imperial stouts and barleywines can keep and develop for longer when stored well.

So for a hoppy beer, the packed-on date matters more than the best before date. A beer can be well within its best before and still have lost most of its hop aroma.

Heat ages beer faster than time

Warmth is the biggest enemy of packaged beer. A widely used brewing rule of thumb holds that staling reactions run roughly twice as fast for every 10 °C rise in temperature. A beer stored at 30 °C ages far faster than one kept cold.

This matters in India. Beer often travels long distances in trucks in the heat and may sit in warm godowns or shop shelves before reaching a fridge. A beer packed two months ago and kept cold can taste fresher than one packed three weeks ago that sat in the sun.

Light is the other enemy. Clear and green glass let in light that reacts with hop compounds to create a skunky smell within minutes. Cans and brown bottles protect the beer.

Buying and storing well

• Check the packed-on date and choose the freshest stock, especially for hoppy beers.
• Buy from shops that keep beer in a fridge or a cool, dark space rather than a sunny window.
• Avoid cans that are dented, bulging or leaking. Skip bottles with damaged caps.
• Store beer upright, cold and dark at home. The fridge is ideal for most beers.
• Drink hoppy beers soon after buying. Do not cellar them.

Tasting the difference

A simple home exercise: buy two cans of the same IPA with different packed-on dates, a few weeks apart if you can find them. Chill both and taste side by side. The fresher one usually smells brighter and fruitier. The older one may smell of honey, cardboard or sherry, with a duller bitterness.

Learning to recognise stale and oxidised notes makes you a much sharper buyer and taster. It is also a core skill in sensory training, where you taste reference samples rather than relying on guesswork.
