As a cool region Lenswood experiences greater vintage variation than the safer warm regions. It shares this characteristic with many of the world’s famous regions and is part of the price the vigneron pays for aspiring to produce the finest of wines.
Each year is different in temperature, rain and wind and the consequence of this is different flavour characteristics in the wines. In general the warm, dry years produce richer, more forward flavours and the wines mature earlier, while the cooler years are more acid, finer, more subtle and the wines take longer to show their best.
One of the joys of wine is to follow the wines from an individual vineyard and see the interaction of vine and climate in the resultant wines. Of course there are a myriad of factors; wind, crop level ,irrigation canopy management etc, which interact to influence the final wine but the temperature and rainfall, particularly around vintage, are crucial in determining the character of the wines.
*Heat degree days (HDD)
Heat degree days is a measure of the warmth of a vineyard region. It is measured by taking the average temperature per day (°C) minus 10 multiplied by the number of days in the 7 month growing season (Oct to April in the Southern Hemisphere). The base is 10 because vines do not function below 10°C.
Lenswood has a heat degree summation of 1278 which can be seen on context of the regions below. To put the figure in perspective the HDD for major world growing regions are:
|Lenswood, South Australia||1278|
|Coonawarra, South Australia||1437|
|Napa Valley, California||1499|
|Barossa Valley, South Australia||1587|
