Maybe you won something in a homebrew comp, maybe you got it from a retiring homebrewer, maybe it seemed great or was on sale
and now it sits unused
What is it?
(and maybe people can chime in to tell you that you need to try it out, or it's worthless)
For me - it's a filter, bought it because it was the deal of the day and I figured if I have a beer that won't clear I can use .. 2 years and it's still in the box unopened
