Mr Frundles Posted February 21 Share Posted February 21 Hi guys, went looking for a Saison yeast the other day. The only one I could find was out of date by a little over a year. Bought it anyway (at a reduced price) thinking that it may not matter. Anyone had any experience with out of date yeast? - or should I just use an Ale yeast instead. Thank you  1 Link to comment Share on other sites More sharing options...
Aussiekraut Posted February 21 Share Posted February 21 Most of the cells will not be viable, so using it would be a massive under pitch. You can try and make a starter and see if you get enough viable cells to multiply in noteworthy numbers. Link to comment Share on other sites More sharing options...

Can't speak for a year. Link to comment Share on other sites More sharing options...

If your an all grainer chuck it in the boil for yeast nutrient if your not going to use it, or plus 1 for what @Aussiekraut said! Link to comment Share on other sites More sharing options...

Yeah, I agree with that, I suppose I was assuming this was for a kit brew. Link to comment Share on other sites More sharing options...
iBooz2 Posted February 21 Share Posted February 21 (edited) @Mr Frundles, dried yeast last a lot longer in the sealed sachet than most people think. If it was stored properly (cool) in your LHBS then use it IMO. I have used dried yeast that are two years past their used by date, without a starter and they were fine each time. I have used liquid yeast about two years past their use by dates albeit in those instances it was with a starter and those brew were fine two. Just recently I used some sachets that were dated best before May 2022 and they were also fine. I must be "The Yeast Whisperer" ha ha. Like @Aussiekraut says, if you can make a very small starter say 100 g of light dry malt in 1 L of pre-boiled water and this will tell you that its ok to proceed and use when it starts to ferment and foam up. Pitch the dried yeast when the starter liquid gets down to about 20-25 C or so, not any hotter. Then you can then tip the lot into your FV on brew day. If you don't know and you want to know the process of making a simple small starter just yell OK. Welcome to the forum BTW.

No problems. In 34 years only had 4 or 5 fail to start. I always have 2 or 3 spare sachets set aside i rotate around. Having said that i had one fail recently IIRC only about 6 months past the best before. That's say 5 out of 640 brews. Perhaps as suggested, do a starter if you don't have a spare sachet if your worried. Edited February 22 by Oldbloke Link to comment Share on other sites More sharing options...
