I think Coldbrew is even more dependent on what coffee beans and roast you use, we have tried a few and they are very different. But so far I liked them all. Maybe you preffer the bitter taste of cooked coffee? That is something that is missing from all our tries with coldbrew.

Definitely not.

But the thing about cold-brew is that it tastes mostly sour to me and nothing else (which is unsurprising given our taste-buds are most sensitive at higher temperatures, and proper extraction of coffee can't happen at those lower temperatures as some compounds just won't dissolve at the same rate, and sour compounds in coffee dissolve the fastest). With warm brewed (+ warm drank) coffee things are more balanced (not just straight sour) and you get the interesting flavour notes from the bag.

I don't think the quality of the coffee I am using is the problem. It might be the variant, but I enjoy natural light roasts (and light roast is already difficult to brew without it getting too sour).

Ours is not sour at all and I'm pretty sensitive to sour stuff.

700 ml water, 50-60 g beans, 24 hours in fridge. When drinking we mix with 3-4 parts water. I always drink cold, wife drinks it hot. Lots of flavour and fun to try the local roasterys seasonal tastes.
