I agree with Dugger - I would bet that you're actual alcohol level is higher than 10%. I would suspect the 'light-on-the-alcohol" part is due to the alcohol taste being hidden by the 'green'-ness of the newly-made wine. I have not made that particular kit, but I have made a few of the Barolo kits and they can be quite good. Let it age at least one to two months, longer if you can wait, before bottling and then give it at least a month or so after bottling to crack the first ones open. If it's less than six months since fermentation you will be disappointed.
In the future, consider getting one of the more expensive Barolo kits as they have more juice/less water to be added to make 6 gallons. At this point, I personally would only buy a kit with a grape pack or raisins included - such as Mosti Mondiale's Renaissance kit or the Master 's Edition Granbarolo, or Spagnol's Grand Cru International - becasue grape packs and raisins give a wine a lot more body than you would get otherwise. And to a small extent additional sugars, which convert to alcohol.
