Does anyone know how long yeast kept in the fridge is good for? I have some from a year or two ago and just wondering whether I can still use it, it doesn't have a best before/use by date

That sounds a long time. Best way to check if it is still okay is to try a little sprinkled over warm water with a little sugar added. If it bubbles up it is still active, If not biff it!

Cheers, it has been biffed!
