At the gentle encouragement of wife, I am in the process of moving my new wine storage operations to a new part of my cellar.
I've cleared it out and built some shelves in that location for my carboys.
But in the process, I've noticed some black mold stains on the walls.
How important is it to remedy that prior to storing wine (and wine equipement) nearby??
Probably not a problem. I have a basement wine cellar and there was some mold on the cinder blocks prior to finishing the basement. You can kill it - at least temporarily with chlorox solution - and maybe risk cork taint - or use H2O2 (Hydrogen Peroxide) on the mold. There may be other product also. Others, will probably chime in.
There is no worry either way in my opinion. Some wine cellars in Europe have at least a thousand years of mold growing in them. I never finished my wine cellar, it was last painted in 1947 and looks like it... I wouldn't worry about TCA and bleach as long as it doesn't saturate a cork accidentally . Another option is boric acid though.
