On its track record, this is the finest Gewürztraminer in New Zealand — and GRAD®1 is its only PCR tested and multiple ELISA tested high-health clonal source.
The GRAD 2 clone series of Pinot noir derives from genetic material of extremely high quality and offers a very serious, carefully and systematically selected and locally developed, alternative to the 'Dijon' clones. Like the widely misunderstood and under-rated Abel clone, the GRAD clone series (development of which is now continuing into its third decade) offers more and better than is being achieved, or even, in all likelihood, can be achieved, in New Zealand from almost all of the range of the Bernard Dijon Pinot noir clones.
GRAD® Riesling Clone 1 in brief:
- A revival of the finest Riesling line yet introduced to New Zealand! The GRAD®1 Riesling is a specially selected and regenerated high health clone derived from a single, over 40 year old, vine of D.S.I.R.

This exceptionally fine Chardonnay genetic line is a regenerated high health version of the old Te Kauwhata 'Pinot Chardonnay' used by Dennis Kasza to make the legendary McWilliams 1960s Chardonnays. It is distinguished by its combining finesse with good depth of richness and flavour. It is hugely superior to Mendoza, and U.C.D. 4, 5, or 6, and also shows more classical (Meursault-like) intensity to its fruit character than many of the recent French clones where understatement and elegance rather than depth and richness seem to have been favoured.
This new V. cinerea x V. riparia rootstock, which is unique to GRAD, is by some distance the toughest and most hardy cool-climate-adapted rootstock available in New Zealand.
Simply the best Viognier clone in Australasia for both wine quality and provenance.
In GRAD's opinion, and based on nearly two decades of observation, the best rootstock for use in close-planted high quality vineyards, and in particular those planted to the Pinot varieties. The GRAD®1 clone is free of detectable virus by PCR test, and was specially selected, through ten years of trials, for its superior robustness and exceptional level of tolerance for dry soil conditions.
The outstanding performance of the GRAD® 106-8 rootstock has proven it to be highly reliable, moderate-vigour, robust, and strongly drought-resistant. In addition, it has the advantage for New Zealand vineyards that, unlike the V. berlandieri x V. rupestris drought-resistant stocks, it is very well adapted to cool climate conditions.
The outstanding performance of GRAD® 44-53 rootstock since GRAD® introduced it to New Zealand, proves it is a highly reliable, moderate-vigour, robust, and strongly drought resistant cool-climate-adapted rootstock.
GRAD®1 Kober 125AA is an excellent choice for vineyards where irrigation and rainfall are limited but where deep soil moisture is retained into the last three months of the growing season. In addition, because of its deep plunging root system it is also of considerable utility in organic vineyards where under-vine cultivation is limited or is not practised.
