Many people wish to get hold of fresh yeast from time to time. I have been lucky up until now, but had problems getting hold of this as the store I get it from had run out. I also think they may be selling up in the not too distant future, so it may well be I will be utilising this link myself too.
By chance I found this link the other day for those of you wishing to obtain a supply of fresh yeast for breadmaking . You can keep this in the fridge, but I would suggest freezing the same in ready portions to maximise your usage and expense. It works out at £4.77 for a 500 g block.
This link also shows various other different yeasts some of which are suitable for wine and beer making.
I hope that this is of assistance to you all
The link is http://amazon.co.uk
Then on the search facility type in: Kitchen & Home then type in yeast.
Hope this helps
