Beer kit hissed when opened

[benparsey]

I opened an old beer kit today and when i pierced the can it hissed a little is it still good to use?

Yes. The can sound like it was under pressure.

Liquid malt is very shelf stable. I does lose freshness over time but it’s sooo high in sugar it really doesn’t go bad. Kind of like honey.
