I'm only on page 76 of who knows how many.
That being said, I had a hair-brained idea. I went to Amazon and they had bulk red yeast rice powder in sealed packages. I'm not sure if that's "extract" or raw powder. Didn't find any regular yeast balls, so I went to google shopping and after poking around there, I found the magic phrase to search is
rice yeast ball The first four hits look to be what we are looking for. Granted two are on eBay and the other two are for the same store, but who knows... the eBay seller could be a regular seller there.
The eBay seller seems, at a glance, to be a regular seller and regularly has combo of red yeast rice and dried yeast rice "for rice wine."
Also posharpstore.com has two different kinds of "sweet rice yeast" for making "fermented rice porridge." I'm thinking that it's probably the same thing we would want for making rice wine, except they aren't selling it that way.
