I use RO water too. The expensive filter (membrane) lasts a few years. You get a lot more water from an RO system than a pitcher filter unit.
For wine making, you want TDS. The yeast benefits from the minerals. Ever read a multi-vitamin label? Lots of minerals there.
As they say, everything in moderation. Reducing TDS has some taste benefits, and can remove other things that might be harmful. Removing all TDS is not so good.
