Trinity Hill Gimblett Gravels Chardonnay, Hawkes Bay The lions share of Trinity Hills grapes comes from the Gimblett Gravels region, in the lee of Roys Hill.

The low fertility soils offer little kindness to the vines, forcing them to work and work to produce small crops of great flavour and aromatic concentration.
