I've seen wheat wine recipes but have never tried it. Most flour is ground wheat I'd start with that over trying to use actual powder flour. That is guessing you're not using some oddball flour. If that's the case start from the source.
Just wondering about the science on it. From my limited experience with rice wine, it seemed as if you need something to break down the starch into sugar. My wine yeast "sourdough " started making booze almost immediately. Is there no need for saccarification?
I think, again not really sure, that the ones who make wheat wine, buy amylase enzyme to convert. How it is lautered or made to be clear I do not know.
