Maipo Valley 1964 Vintage Report
The 1964 vintage in Maipo Valley is the ultimate redemption story. After a chaotic start that threatened the crop, the season turned a corner to deliver a stunning finale.
Early challenges emerged with a disrupted flowering phase. 6mm of rain during the bloom caused significant *coulure* (shatter), naturally lowering yields and concentrating the energy into fewer bunches. However, the threat of frost loom large, with 1 distinct cold snaps keeping vineyard managers on high alert during budbreak.
Summer conditions were balanced, oscillating between warm spells and refreshing intervals that kept the ripening on a steady track. A key factor was the dramatic diurnal shift (12.9°C), ensuring that despite the daytime warmth, acidities remained razor-sharp.
Harvest proceeded under mixed skies, requiring agility to dodge the 23mm of rain that fell sporadically during the picking weeks.
**Style:** Classically proportioned wines with good balance and terroir expression.
