Noah, I think this is a great topic to raise.
I’m no winemaker but this is a topic I have have often discussed with NZ pinot noir producers. NZ pinot noir producers are just as interested in it as Jim and other Oregon producers and, I understand, have similar experiences.
NZ pinot noir in the 1970s was founded on the so-called Abel or Ata Rangi clone (said to be taken from a cutting from Domaine de la Rominee-Conti that was confiscated at Customs and then given to our Research and Science Department). It provides silky mouthfeel, good tannins and savoury flavours. It is a large part of what I think of as the signature Ata Rangi or Martinborough mouthfeel and flavour profile of savoury and brambly flavours.
Pommard/Clone 5 is widely planted and arrived in NZ soon after Abel. Winemakers I have spoken to don’t favour it as a single component of their wines. But it delivers solidity, weight and structure to their wines.
The Dijon clones arrived in the early 1980s and were very popular. The wines the clones produce is less structured than Abel or Clone 5 but add more perfumed and elegance, I understand. As Meadows indicates, in NZ too, after the initial enthusiasm, winemakers now only typically want Dijon clones as part of a mix.
There are now more than 20 clones widely planted in NZ. It is even believed there may be some Wadenswil in NZ, confused with Abel. A recent arrival, Escarpment and others are now growing the Australian Mornington Peninsula clone MV6, a clone producing some of the best Aussie pinot noirs.
Some winemakers barrel separately their parcels from individual clones and you can see some signature from the Abel, 10/5, 5, or whatever it is. Ultimately they blend for bottling.
The modern trend is for NZ winemakers to plant a range of clones to try to achieve more complexity of flavour eg Craggy Range planted eight clones at their Te Muna Road vineyard. Ata Rangi now has over a dozen different clones planted. Pinot noir is inherently genetically unstable, so there may more complexity than people think in NZ vineyards.
