StarSan Question- (1st brew in 6 months happening tomm)

Ive finally got a chance to brew some beer tomm, for the 1st time in 6 months. Im basing it off a clone recipe for Blanche De Bruges. My large container of StarSan is probably about 10 months old....(undiluted of course, Im referring to the actual container of pure StarSan)....ive been storing it in a cool dry dark closet in a black plastic bag. Could I generally assume thats still ok to use?....I do not have the materials for a pH test.

I wouldn't see any reason to worry, that stuff lasts a long time.

Foam on!!!

You should be fine.

I would think it's fine.

It's fine.
