Well I bottled it all today and had a cheeky taste and you can certainly taste the Raspberry. It's not too strong to too weak either. For 8 of the bottles I ran out of sugar

Have put them away now, with 8 bottle (1/2pint) going into my maturing cupboard (I leave these bottles for special occasion, don't really get touched for 6months or longer) and the rest went under the stairs to be enjoyed in 4 weeks time.
Will update this thread to let you know how it goes.
