While you are correct that Aspergillus oryzae is added to rice to make sake, so too is yeast. I could be wrong but I believe the mould culture is for taste but I am not sure that it produces alcohol, where as the yeast certainly does.
]]>So people with strictly a yeast allergy may not have trouble with sake, while those of us with mold (but no yeast) allergy do – and vice versa for other fermented items. For instance, I react to sake, but not to beer or wine (which are brewed using yeast, not mold), and I did test positive for mold allergy, Aspergillus being one of the specifics that we could actually separate out in the testing setting. I do not have a yeast allergy, either from observed reactions or from test results.
So I would suggest including mold allergy as a possibility in your list above. At least in my case, it IS the single culprit allergy.
]]>I have a yeast allergy (and a few others) and wanted to check sake; it’s good to have found the information I was looking for. Now I know I need to avoid it, too. Thanks! I did feel bad the last time I had sake. I wasn’t sure what yeast they use. I have a Saccharomyces cerevisiae allergy but I haven’t been tested for other species; I think in general, yeasts are not great for me. I have never tried kombucha for this reason.
Yeast-containing alcohols have a very big effect on me. I used to think it was the alcohol content, but now I know it was the yeast. It also explains why other people were able to take hangovers – I have a feeling mine were a lot worse because of the allergy effect.
