one of the bestthings i can sayto a question such as your is one size does not fit all.....while all the answers above are right on target there is still a reason for you to just go drink some of yours right now and forgo aging.....
why?
here is the why....i am assuming that there is a newness to your winemaking history....i assume that for one reason....that reason being that you *asked* that question...an experienced wine maker knows the answer
one of the extremely wonderful benefits of winemaking is that the experience teaches and nothing teaches better than experience....
so lets say you are getting 25-30 bottles from this kit...why dont you start enjoying a bottle of your new past time every two weeks and start another kit of whatever in oh say 30 days....by the time you are into your 4th, 5th or maybe sixth bottle your next wine will come online.....and you can mix the newest wine into your schedule and so on...my point is that you will *experience* for yourself just what aging does.....and then you will have some of this wine 1-2 years or so down the road as well
the wine will tell its tale and it also will tell on you by that i mean it will talk to you in terms of whether or not your winemaking procedures carried it properly to term
some wines taste great young too! and yours may be one of them...how will you know if you just go age it for a year? you wont. and some people that you share with might just like it BETTER young....you may not, but down the road if you keep things going, you can pull out two of the same varietals that you have aged for different lengths and both of you will be happy...and you will be able to do it because you experienced it for yourself.
anyway, that is just my small 2 cents
