First, i like to say that this is a great forum. I'm a newbie and glad to find this website. I do have a few questions and i appreciate any support that you may have. First, some of my wines seems a little bland. More water down than a good body flavor. I use Welch's concentrates. Will it help if i add more concentrate to start off with and to finish when i sweeten? Also, i've been using spring water to top off with when i rack the wine. Secondly, it seems that my wines have a little sulfate smell or taste to it. What causes this? I'm thinking it's coming from the campden whenever i sweeten the wine back up. Could that be and is there anyway to eliminate this smell or taste?
