Our Environment - Soil

The main soils of the Doubtless Bay area are volcanic (especially on the Rangiawhia Range of the Karikari Peninsula) and several types of sand.

The Doubtless Bay Wine Company vineyard at Lake Ohia is situated on a terrace of extremely free draining Ohia sand. This long narrow terrace rises out of neighbouring peaty swampland, including the largely drained Lake Ohia, which was once an ancient Kauri forest and later the site of Kauri Gum diggings early in the 20th Century.

One of the surviving remnants of the predominantly Dalmatian gum diggers of the area is an old grapevine planted just half a kilometre from the present vineyard in the vicinity of old gum diggings.
