They are a few organic supermarket in Wuppertal town but I would recommend this one in particular — If you are stuck there for whatever reason, that’s where you can find your unsweetened, unsalted, unoiled soy milk at the best price and goes for other health maintenance products. — All the recognized labels that you want to see are there(bio, bioland, etc…) — It’s a couple of stations away from the main station(Hauptbahnof) — Staff is ready to inform, friendly sometimes with flirting eyes(damn, we are far from hamburg!) –They have a connected bakery with fresh pastries, sometimes vegan, just ask or just try if you’re an omnivore
