Some time ago, I wrote that rosé should only be drunk south of Lyon, but one could start on the first bottle around 10.30 while brushing away the last shards of breakfast croissant. Although I received appreciative comments, I am no longer sure that I agree with myself. I recently discovered Domaine de Triennes, which is a serious wine with length and structure — far better than the average supermarket rosé which would work perfectly well as an ice lolly.
