Why do drinks made with no dairy or sugar or anything (like unsweet tea or black coffee – just water and leaves/beans) sour or mold over time?

Question

I’d think the factors that cause mold would be stuff like sugars, dairy, sweeteners in drinks. Water doesn’t really do that alone, so why does water + leaves mold?

This question has been bothering me and I’m finally asking because it’s driving me crazy.

Ever notice what happens when you leave vegetables in the fridge for too long or some fruit on the counter? Yeah it eventually goes brown and mushy and yucky. Well this happens to anything that’s organic and biologic like plants… where do leaves come from? Yep you guessed it, plants, and so I hope now you can see why teas and black coffee can still go mouldy, because this decay is one of moulds favourite things to feast on. One man’s trash is another moulds treasure
