Be interesting to know how it turns out, what was the starting sg by the way? If you have the starting sg of when you made some without the extra RGC it would be interesting to know the difference too.
Hi,
I've not taken the SG, partly because I'm not sure when to take it. Should I take it at the time I put the yeast in or several days later when I top up the demijohn with water?
You've asked an interesting question, as and when I make another I'll measure the SG.

I take the reading before i add the yeast.

Yes, me too Chippy-Tea. if you know the starting sg and final sg you can calculate the alcoholic content, otherwise you need to have a filtered sample of your finished wine and buy either a 'Vinometer' which is a glass instrument which looks a bit like a glass thistle shape on a stick and has limited accuracy for around £5 or a Refractometer which is very accurate but cost from around £20 to 'HOW MUCH!!!'
There is a third method, highly inaccurate and involves a couple of aspirin the next morning but quite enjoyable.
