How long does a mini keg last?

Probably about a month before it slowly starts losing the hoppy goodness. Keeping it in the fridge should help.

Yep. Try to keep it as cold as you can w/o freezing for maximum freshness. People hyperbolize how quickly it goes bad but for a few weeks you should be fine. It will still be good after that but it won’t be at it’s best.

I find they usdually last until they’re gone.

Then I cry.
