Wyeast Nutrient

[XXXBrewDude]

Anyone know if the Wyeast Nutrient Blend will expire? I've had some in the garage storage for 3 years.

Wyeast says it's good for 1 year:

Of course they do!

Are you implying that they are hiding something and it lasts longer or shorter than a year? Enquiring minds want to know.

I think its just yeast lysate and some minerals, which should be pretty shelf stable. I bet your fine. At the very least, you won't be hurting the yeast.

It sounds an awful like other expiration dates that turn out to be not so much an expiration as a best before date. That said, spending $2.50 a year on a fresh tube seems like cheap insurance

I agree. I have a tube that has been sitting in my cupboard for at least 3 years. It worked fine for a mead and a cyser last summer

I have a tube I've been using for a couple of years, but I only use it in starters. But who knows if I even need it?
