Natural coverings from the cold northern and eastern winds have been added to my vineyard with a willow belt from the west.
Thanks to this, it can be considered that the vineyard is located in the so-called “warm zone” on the south-western slope, with an average slope of 15°, at a height just below 350 m above sea level.
This is confirmed by the following parameters: GDDC and active days in the year, measured using two Efento logger devices from Kraków.
| GDDC up [°C] | 2016 | 1362 | 2017 | 1221 | 2018 | 1629 |
| GDDC down [°C] | 1402 | 1250 | 1605 | |||
| Active days up | 169 | 173 | 200 | |||
| Active days down | 167 | 181 | 205 |
As you can see, the season 2018 was unusual. If you count GDDC until the time of grape harvest in September, then parameters would be, respectively, less ie: GDDC ~ 1500 and active days ~ 175. It’s still a lot.
Without information on the actual GDDC / SAT values and active days, it is difficult to make a decision on the vine species in a particular vineyard.
In addition, any change in the heat accumulation of the vineyard or cover can be assessed for the impact on the conditions in the habitat.
