Vintner's Harvest Bergamais. Sounds good. Beaujolais style, should be good to drink fairly young especially when sweetened. And the kit probably doesn't matter in this case, but I'd like everyone to get in the habit of being specific when asking about kits, because sometimes it matters. (EG Winexpert Riesling only narrows the field down to 5 or 6 (guessing) possible kits.)
Sweetening when two people want different results...Bottle the batch with sufficient sweetener for the least sweetness (in this case semi-sweet for your friend). Then the person (you) who wants it sweeter can add a small amount of sweetener to their glass.
It is the Winexpert Vintners Reserve. When using plain Ole Table sugar you add 2 cups of suagr to 1 cup of boiling water and stir it well and let it cool to room temp and add it slowly to a wine that has been stabilized with both k-meta and sorbate and add it slowly and taste often as if you over sweeten then you will have to cut it with a like dry wine.
