As someone who regularly makes cold brew during hot summers, the tale is that the acidity is lower — or at least of a different kind.
Hot brewed coffee starts to taste bad after a few hours if you let it go cold, cold brewed coffee tastes differently from the start, but won't develop that bad flavour even after a week in the fridge.
The key for a good cold brew is however that the bean/roast is of very good quality. And it is quite simple to make. The way I do it:
1. Grind coffee coarsly and put it in a glas jar that can be closed. The amount of coffee can be adjusted quite freely, but I'd go with one fourth/fifth of the volume of the jar. More bean = more concentrated coffee.
2. Add cold water and stir
3. Put in the fridge and stir at least once in the morning, once in the evening.
4. After ca. 24 hours you can run the whole thing through a coffee filter to extract the coffee. It is also possible to reuse the coffee-sludge once if you add some fresh beans.
That is not too complicated and worth a try. Please avoid pre-grind cheap coffee for this, It will taste like bullshit.
