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 1882, 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. It’s marketed as part of their “The Olds” Collection, which also includes Old Overholt, Old Tub, and Old Crow. Old Grand-Dad is currently released in three different ongoing bottling proofs: 80 (changed from 86 in 2013), 100, and 114.
