Out of date yeast

[Nick Masters]

Hi all
I have just put down an extract lager but it was slightly out of date. Should I use this yeast or get some new stuff from LHBS? It is only a 5g sachet and the ones I usually use are 11g. Should I measure out 5g or chuck the whole new 11g sachet in?
Cheers
Nick

Buy some new and better yeast.

Do you have ferment temp control so you can use a true lager yeast or are you doing ambient temp ferments?

If you buy an 11g packet use the whole thing for sure - once it's opened nasties can get in.

edit: having said all that, the yeast you have might do the trick.
But better to be safe by buying new stuff if you can.
