Wine Advocate-Parker :
Somewhat less evolved than the 1971, and for me always a shade less interesting and complex, the 1970 Yquem is a large-scaled, rich, full-bodied, fairly alcoholic Yquem with significant flavor interest as well as crisp acidity. Unlike the 1971, which is close to peak maturity, this wine has a long way to go and is impressive, but not yet revealing all of its potential. Anticipated maturity: Now-2025. Last tasted, 11/84.
