Marlborough 1973 Vintage Report
1973 was a test of resilience for the vignerons of Marlborough, who fought against the elements from budbreak to harvest.
Early challenges emerged with a disrupted flowering phase. 51mm of rain during the bloom caused significant *coulure* (shatter), naturally lowering yields and concentrating the energy into fewer bunches.
It was a cool, classical season. Reaching only 1117 GDD, the summer never really spiked in temperature, favoring the development of fresh aromatics over sheer power.
The finale was fraught with tension. A deluge of 93mm during the harvest period forced an expedited picking schedule to mitigate botrytis risks, rewarding those who sorted ruthlessly.
**Style:** Classically proportioned wines with good balance and terroir expression.
