I was making a farmhouse ale and I finished waiting 2 weeks after bottling and tasted the first bottle---getting a slight sour flavor- hops are supposed to somewhat citrus but I do not think they should be this intense. It does not taste bad, but not what I intended. Get the crystal ball out, I am thinking I either got some wild yeast or other contamination. This is the first one in 9 years of brewing- assuming from what I have read, it is not going to cause any illness. I brewed another batch using the same equipment, tasted the first bottle and no hint of sour, so I do not think it is any persistent infection with the equipment. Looking for any thoughts. Thanks
