Mendoza 1973 Vintage Report
1973 was a test of resilience for the vignerons of Mendoza, who fought against the elements from budbreak to harvest.
Early challenges emerged with a disrupted flowering phase. 81mm of rain during the bloom caused significant *coulure* (shatter), naturally lowering yields and concentrating the energy into fewer bunches.
The growing season was solar and generous. Accumulating 1917 Growing Degree Days (GDD), the summer provided consistent warmth that drove steady sugar accumulation.
The finale was fraught with tension. A deluge of 160mm during the harvest period forced an expedited picking schedule to mitigate botrytis risks, rewarding those who sorted ruthlessly.
**Style:** Powerful but variable, with the best wines balancing the heat with careful selection.
