CellarScience - AD332B Fermaid O (120 g)

So, I'm a big fan of doing things as naturally as possible and jumped at the chance to buy a yeast nutrient that comes from an organic source. I've used this several times previously to buying this and there is at least a very small difference in flavour in some (not all) of my side by side brew tests that I've used this in. When I use Fermaid O, there is an apparent lack of sulphite smell/flavour compared to using DAP or Fermaid K even in primary fermentation. That, and the fact that I know it's a natural product will be enough to keep me buying it (though I hope to find a decent UK source in future).This replaces DAP, Fermaid K etc.TIP: get this out of the packet and into a jar with a silica gel pack in it as Fermaid O has an insane affinity for moisture and becomes very sticky, very quickly!
