We visited this winery as a group of nine (including three under two year olds) and had a great time.
The wine tasting is very flexible and the German lady who saw to us was knowledgeable and good fun (once she warmed up). The wines are excellent and the measures are generous.
Another point worth making is that the estate setting itself is beautiful.
Be sure to try the "Sparrow poop" dessert wine, it is incredible
