A bottle of single malt scotch on a table next to a blackberry cocktail.

Sir William Smash, aka Blackberry Whiskey Smash

A homemade whiskey smash gets an upgrade when you mix in some quality whiskey and some fresh blackberries. A blackberry whiskey smash is ideal to serve when blackberries are in season, or you can make it anytime using frozen blackberries. We made ours with Old Pulteney 12 year Single Malt Scotch, but you can use your favorite whiskey or scotch.
