Amphibolite is a metamorphic stone generally formed from gabbro or basalt with a high concentration of iron and magnesium prevalent in the vineyard over a bedrock of gneiss. "Subtle aromas give way to a palate that's concentrated, full-flavoured and explosive, with lots of texture and a rocky mineral tingle. Pear skin and a bite of Golden Delicious apple. Cashew richness adds depth. I love the saline finish."
