It does seem to affect the taste...for the better.
I've always used it but pretty much sporadically, meaning whenever I thought about putting some in the water. Then I made my own ACV and had more on hand to use, so I just put it in the water each time I refilled. After I started using it all the time, my regular egg customers started making comments on the change in the taste of my eggs. "Less sulfur taste", "creamier flavor", "more mild", "now I can eat eggs and I've never been able to before without upsetting my stomach" kind of comments. I'll never go back to not using the ACV after the rave reviews that kept coming after using it full time.
