The short answer is that natural wine can taste like any other kind of conventional wine (we like to call these stealth natural wines) or it can taste quite a bit different, as production methods can vary and potentially be lighter, or in a style you've never had before (like orange, pet-nat or amphora).
The natural wine community is also more accepting of some qualities in wines that conventional would consider a flaw, like Brett, some oxidation, or volatile acidity. We would consider these in high amounts to also be a flaw, but in many cases a touch of these qualities can ultimately improve their flavor and texture and be happily accepted in a natural wine.
