How to read MM/DD/YY date codes

Standard American date format: month, day, year. Slashes, dashes, and dots all work — e.g. 04/12/26, 04-12-26, or 04.12.26 all read as April 12, 2026.

Green Flash's code is a Best-by — drink before this date for full character.

Where to find the date code on Green Flash cans and bottles

On Green Flash cans and bottles, look on the bottom of the can first. If not there, check the bottle neck label or the back of the can for a small printed or laser-etched code.

If the code looks smudged, partially worn, or printed in light ink, try angling the can under a bright light. Phone flashlights work well. The Freshie camera scanner can read most codes even when they're partially obscured.

How long is Green Flash beer fresh?

Green Flash produces a range of styles, each with its own drinking window:

These are guidelines, not laws — well-stored beer can outperform the curve, while heat-abused cans can stale much faster than expected. Storage temperature matters as much as age for hop-forward styles. Cold storage (under 40°F) extends every window meaningfully.
