I've made Youngs,Solomon Grundy,California Connoisseur,Beaverdale & Selection kits.
I would suggest the more grape juice concentrate in the kit the better.
TBH I found the whites/roses were better than the reds at the lower end of the price range.
I made the Beaverdale Shiraz & found it a bit thin,and a year on hadn't aged that well,but the Chardonnay & Chablis blush were okay.The Selection kits are superb,but its hard not to baulk at the price.
I think if I were you I would have a go at a few WOWS or some of CJJ Berrys recipes to start with,or a kit from the lower end of the price range (just to get used to the process & build a bit of confidence) & then move up through the kits in terms of price range.
