Iris Rose 2026

The jewel in the Gimblett Gravels crown, Cornerstone was planted in the famous Gimblett Gravels appellation, the only one classified on soil type and not the geography. The free-draining soils were formed after the flooding of the Ngaruroro River back in 1867. While it naturally has low rainfall, if we get a good downpour, the next day we wonder if rain fell at all, with water quickly wicked from the feet of the vines to allow just a quick drink.

The old adage ‘treat them mean, keep them keen’ is apt here. Our Cornerstone vineyard can often be one of the messiest vineyards among its neighbours, but where it may not win a beauty contest it more than makes up for it where it counts – in the bottle.
