Burgundy was still somewhat in the doldrums throughout the 1970s, with little in the way of domaine bottling. After the adulterated wines of an earlier period the mantra was now to make pure wines and accept that Pint & Chardonnay was naturally a lighter style of wine. The decade began and finished well but there were some tricky vintages in between. However there were several superlative vintages in the 1970s for white wine such as we have not seen since, and these included two of the biggest crops then on record.

A large vintage of excellent wines, though the crop was at the time easily the largest on record. But Chardonnay is much less sensitive than pinot to cropping levels, and a large crop is usually a sign of a healthy vintage, which was indeed the case.
