I made some Catawba wine. This is probably the 8th batch of wine I've made and this one didn't turn out good. Has a slight sour taste to it and I added pictures of the settling that is in the bottle. Can anyone provide any insight into what went wrong? I used campden tablets, I racked it a few times....my initial thought is I just didn't wait long enough for all of the sediment to make it's way to the bottom before bottling, but I'm still just learning.
