Hi sorry I did not finish off your question. Diurnal swing depends on the area. In Hawkes Bay we are not looking for a huge one and usually get between 8 and 10, where in Marlborough where we grow Pinot we get 10-13, we even have an area which we are looking into at the mo which has a 14-16 rate. Rain fall, Gisborne is late 500mm, HB is similar and Marlb is mid 400 up to mid 500mm. 60% fall in the winter as these areas do not get snow on the plans. Growing degree days are Gisborne late 1400, HB 1400, Marlb 1200and Central Otago 1050. If you go into France it is 1300 to 1400 and California is 1700-2100 so a lot more heat units in California. Soils, being old river beds 150 years old in HB with some areas being old volcanic run off which is 10,000 years old, top soils a silt and loam with some clay areas. Also have a type of clay called Papa which is very dry and we have to drill for 200 feet plus to get water, this is in Clifford Bay with river beds on top and fine silt on top of that. Valley's are mainly silt loam leading down to rivers where we get gravels ranging in density. Not much limestone, plus different to France anyway.
