So....
I'm at the other end of the spectrum. I've been involved in home winemaking since May, 2010. I've made 31 kits and one batch of cherry wine from fresh fruit.
I would offer a more...cautionary...note to someone new to the hobby. I have found that it has taken me a few years to understand the consequences of various decisions I made, or circumstances that I encountered, in making my wines (particularly the first 10 kits, or so). Making more kits in this steep section of the learning curve only would have meant that I would have replicated the same mistake more times before I had time to see the ramifications.
Now some of this has to do with how much wine I consume. Even though my early kit attempts were "rough", I enjoyed them...even while "young". And most friends I shared them with enjoyed them, too. I drink about a bottle a week...maybe six a month, so around 2 kits per year satisfies my personal consumption. I've averaged making over 5 kits/year. Even with gifting, sharing, and such, I've easily got over 400 bottles of wine aging in my basement/wine cellar. More than I can comfortably store. I'm at my storage limit, and frankly, some of my older wines that I still have (a 2011 WE Selection Pinot Noir, for one) may be edging past peak. Or maybe I'm making so much better wine now that any technique flaws in my early attempts are now showing up in the aged final product and are more glaring to me, and those wines aren't as enjoyable to drink.
So I've decided to make three kits per year...enough to keep my barrel full, satisfy my personal consumption, and give me a couple cases to give away. I also usually make a specialty wine kit per year, and will probably try my hand at another batch of cherry wine. If I start to see my stock dwindle, I can put another kit or two into the "rotation".
Do some math and figure out your consumption rate and any storage space limitations you have, and factor in how long...maybe as long as two years...it will take for you to really critically evaluate your wine. How much do you need to make to satisfy personal consumption and gifting? How many bottles can you store? How many kits can you make to satisfy these factors and allow you to build a cellar of aging wines?
At the end of the day, it's a hobby, right? So it's all good. Have fun. Share with friends. Laugh and learn. I once had a professor from the Philippines who, when asked a question that did not have a definitive answer would say, "Whatever make you happy!"
