Treloar Muscat de Rivesaltes 2009

Domaine Treloar Muscat de Rivesaltes 2009
15% abv; 105 g/l RS. What a nice wine this is! I was a bit apprehensive in ordering this because I have only tried one M de R before that I truly enjoyed (Domaine de Blanes 2008); all others I have had have simply tasted simple and sweet to the point of being cloying.

But since I've enjoyed everything else from Treloar, I trusted the producer enough to have bought one of these as well. It is obviously sweet, but what sets this apart from all but one of those others I've had is that it isn't cloying at all. It has wonderfully clear and bright Muscat aromas. It is actually a refreshing drink despite all that sugar and had a nice, slight touch of bitterness on the finish - it worked well as an aperitive, perhaps a bit too well since we already finished the 50cl bottle and I'm not even done cooking!

Can someone explain how this manages to be so refreshing? I don't sense much acidity in this and the sugar is high. So why does it work in this wine and in the Blanes?
