Sour beers are becoming one of my favorite beers, the first one I tried was the Jolly Pumpkin la Roja and the love started. Recently my wife surprised me with a Petrus and I loved it even more. I'm looking to brew something like it with a strong sour flavor. I'm thinking of starting with a blonde, which will probably be this http://www.midwestsupplies.com/blonde-ale-all-grain-kit.html. I'm intimidated by this because the more I read, the more I'm lost. I have read that some brewers don't boil the wort, some do, some add hops, some don't. So, the question is, what do I need to change to make this kit into a sour? I'm just lost, it may be a stupid question, as I'm so new to this but I would rather ask it than ruin a batch of beer.
