Poolish problem

Toast

Hi,

I have been experimenting with Poolish for a couple of weeks now, and love the results, except I am having a problem with my dough fermentations not doubling in size ? I got my recipe online by a guy apparently well known, but I cannot remember his name. My poolish always works great, it has 16 hrs fermentation because our house is not that warm, but it is always vigorous by the time I use it. The poolish has 250 + 250 water/flour + 1/8th tsp of IDY.  The main mix has 250 g flour + 90 g water + 1/2 tsp of IDY - BUT it just does not seem to rise that well....... do you think I could increase the yeast in the main mix to more than 1/2 tsp - would this help ?

Thank you very much for any suggestions !

Check the age of the yeast; maybe out of date. I think there is a way to test its viability. web search should find it.

 

Thanks gavinc,

I can't see it being the age of the yeast because the Poolish works absolutely fine. It is only the bulk fermentation that does not seem to work that great.

I use yeast over a year past the expiration date - no problems. I would suggest you look at the starter - as in is it as potent as the others. Rise time isn't the best indicator. Enjoy!
