The Harvey Wallbanger was arguably the most popular cocktail of the 1970s - helping to make Galliano the number one liqueur imported in the United States during that time. However, the Harvey Wallbanger has since fallen out of fashion. The original drink falls flat by today’s standards, but with a few adjustments it can be balanced, refreshing, and dangerously easy to drink. Enjoy this updated recipe responsibly. Cheers!
