"It has intensity, balance and flavour with a structure that has audacity, with freshness and complexity."
So for him and Kirby Wednesday was a long-awaited day, for what they watched being carefully bottled was more than just another style or vintage.
"To make a wine such as this is something I really look forward to... it is my special baby."
The grapes were from 30-year-old vines and the fermentation time in the special barrels was much longer than normal.
The result is a wine which has continually gathered up top awards and accolades, and has created a "must have" stance with a large number of wine enthusiasts and wine investors, and those who simply want to taste something special, and brush aside the $195 a bottle price.
There is also a touch of patience involved here as it is a wine which needs to age further to deliver its absolute best - preferably up to 10 years, while with top cellaring it will develop up to 20 years.
"It's all hand crafted — velvet gloves material," Kirby said with a smile.
Through the whole growing, picking and production process a small artisan team works with great care, and that continues to the specialised bottling, where the bottles are corked with those tops then red-waxed for sealing.
"All part of the hand-crafting," Kirby said.
Turvey said the 2018 Endeavour was now available, and like the previous releases is a strictly limited edition.
The orders were arriving even before bottling started.
