Viticulture - Global warming
3 important questions on Viticulture - Global warming
What is the impact of global warming on the wine industry?
- Coming years, wine industry will challenges that will lead to major changes
- Hot climate --> Mediterranean, will no longer be suitable for growing wine grapes by 2050 (E.g. Tuscany - Italy, Napa Valley - US)
- Colder climates will start growing vines
- Wine wine producers will do everything they can to protect their existing vineyards and have already started to implement solutions. But despite this, global warming has already affected both the taste of wines and how grapevines grow.
What is the organoleptic profile?
What are the 4 main solution ti deal with global warming?
- EARLY HARVEST: maintain the high level of acidity, important to produce a balance wine
- MALOLACTIC FERMENTATION
- CHANGING GRAPES VARIETIES: more adapted to the hydric stress (E.g. Mourvèdre). Creating American rootstocks that are more resistant to climate change. Scientists are also creating new varieties of vines or clones
- REDUCE THE RATE OF PHOTOSYNTHESIS: by orientating their vines to the north instead of the south in
