Rhonda and David Maples know the King Valley very well. Rhonda's parents owned a farm across the road from Gracebrook, and during her holidays she would work in the local vineyards. David's parents also owned dairy and tobacco farms where he acquired the horticultural skills that are invaluable within the vineyard. Growing conditions here are highly favourable but in drier years supplementary water can be applied as the soil moisture drops. Some applications of organic fertilizer through the irrigation system keep the vines looking at their best. Canopy and vineyard work take up most of the available daylight hours. Grapes are exactingly pruned, the aim being to achieve low to average yields of the highest quality.
