During the postwar years, Aaron continued to write about wine, now for the popular market: with Beard, he co-authored "How to Eat Better for Less Money" and with the book critic Clifton Fadiman, he wrote a coffee table book, "The Joys of Wine." He was a judge at the New York Wine Tasting of 1973 which featured many of the same French and American wines that would be judged at the Judgment of Paris. In 1984, he was honored by the vignerons of Bordeaux, the shippers of Burgundy, Beaujolais and Champagne with gala parties in each of those regions, in celebration of Sherry-Lehmann's half-century and of Aaron's contributions to the international wine trade.

Jack Aaron died in 1967 and his place in the business was taken by Sam's nephew, Michael Aaron. Sam Aaron retired in 1990.
