Out of date yeast - Safale

[timtoos]

Hi,

I have a few packets of dried yeasts - Safale 04 (x4) and (4 x) US05 variants.

The 04 expiry date was Jun 15 and the US05 this month.

I have stored them in a cool place for about 6 months after getting them then put into the fridge there after.

Should I just throw them out?

Whats the worst that could happen? Will they give a bad fermentation/off flavours etc or will rehydrating them prove they are ok before use?

Thanks

Just rehydrate them before use and they should be good to go. If there not viable re-hydrating will let you know. A packet of dried yeast has LOADS of yeast cells far more than a 2L starter

I would rehydrate them to find out, they are likely to be ok.
