Hi there. I'm guessing you're from the UK? I am too. I think the user base of the forum is predominantly American but I could be wrong.
I'm fairly new to wine and beer making myself so don't take what I say as gospel but I would like to offer my opinions and hopefully can be of some help.
I got my first kit from Wilkinsons but it was a beer kit. They appear to be cheaper kits and although I've not made any, have heard them to be poorer quality. My advice would be to see where your nearest local homebrew shop is and use this for your equipment and also advice. I'm in Worthing, West Sussex and have a fantastic shop near by. The owners and shop workers all offer great advice, even when it goes against them making a sale.
Your wine looks fine to me. I think you've just got nervous and made some rash decisions. It's very easy to worry that things have gone wrong but its worth remembering that these kits are sold all over the world and have been tried and tested. Yes it's probably true that a greater quality wine can be made from them with expert knowledge and leaving for longer before bottling, extra racking, extra things being added etc.
... But, follow the instructions and as long as you sanitise properly and ferment at the correct temperature, you will end up with a drinkable wine.
I have mainly brewed beer and am only just getting into wine. I found that with the kit I just made I needed a 23L carbouy. Which you won't get in Wilkinsons. It seems these are needed for wine making if doing the 30 bottle kits so I would advice buying one of these.
I bought a plastic one from my local homebrew shop for £20.50 but only found 1 on eBay which was £26 including delivery.
As far as kits go, from my experience and the advice of others including my local homebrew shop. (Not to mention a little common sense) You get what you pay for.
I bought a £30 kit (30 bottle) and although it wasn't bad, the quality difference was easily noticeable compared to even a 6 bottle kit of House of beaverdale. ( the 30 bottle kits are £48 )
I now have a WineExpert kit (30 bottle kit at £55) I have just racked into my carbouy and tastes during syphoning. I am excited about trying my first bottle in some time.
I wouldn't hold out too much hope in your current kit due to stopping fermentation too early and racking off part of the kit Seperatly. Not to say its ruined or anything, just that it may not reach its full potential.
Keep going though, as I keep telling myself. If you havnt already, buy C.J.J First Steps In Wine Making. It will inspire you!
