Hello Brewers!

I am still a noob to this, but I want to brew my wife something that she’d like.

I don’t yet have the equipment to do an all grain, and I am reliant on extracts.

I was wondering if anyone has experimented with adding flavour ingredients, like cherry for example, to an extract? If so, when and what have you added? And is this going to be an expensive process of trial and error?
