The Old Grand-Dad brand was created by Raymond B. Hayden and named after his grandfather Meredith Basil Hayden, Sr. The bourbon has been in production since the 1800's, including during Prohibition when it was produced by American Medicinal Spirits Co., a pharmaceutical company. The brand has changed ownership numerous times since it was originally created and is now owned by Beam Suntory and marketed as part of their “The Olds” Collection which also includes Old Overholt.

In the early 1970s, Benriach broke convention in Speyside by returning to distilling batches of whisky in the old, 19th century style, using malted barley smoked with Highland peat. This wood rich Highland peat imparts distinctly sweet and smoky notes into Benriach peated whiskies. Benriach The Smoky Ten has been crafted from a combination of unpeated and peated spirit and three cask matured for at least ten years in a combination of bourbon barrels, Jamaican rum casks and toasted virgin oak. The whisky is then expertly married together to create sublimely smooth layers of sunripe fruit, aromatic smoke and toasted oak spice, lingering into the perfectly balanced sweet and smoky finish.
