Rioja 1977 Vintage Report
Defining the 1977 vintage in Rioja requires looking beyond the averages, as it was a year of contrasting fortunes and precise timing.
Early challenges emerged with a disrupted flowering phase. 171mm 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 1015 GDD, the summer never really spiked in temperature, favoring the development of fresh aromatics over sheer power.
Harvest proceeded under mixed skies, requiring agility to dodge the 39mm of rain that fell sporadically during the picking weeks.
**Style:** Elegant, transparent wines defined by finesse and vibrant acidity.
