How to read DDDYY date codes

Five-digit Julian date — day of year (1–365) followed by 2-digit year. 10226 means day 102 of 2026 (April 12, 2026). Common in older brewing systems.

Sufferfest Beer's code is a Pack date — the date the beer was packaged. Drink within a window after this date based on style.

Where to find the date code on Sufferfest Beer cans and bottles

On Sufferfest Beer packaging, the date code is typically printed on the bottom of cans or laser-etched on the bottle neck or shoulder. Some bottles also print it on the back label.

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 Sufferfest Beer beer fresh?

Sufferfest Beer 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.
