Proof is controlled both as it enters the barrel (barrel entry proof) and as it leaves the barrel (bottle proof) by adding water to achieve a desired flavor profile. Barrel entry proof has changed over the past two centuries. The bourbon of the 19th century had a barrel entry of 100 to 103 proof. After the repeal of Prohibition, barrel entry proof levels began to increase. This 2022 Master’s Collection features the 100 proof entry of a bygone era and is presented at 90.4 proof. The result is this Historic Barrel Entry, a rich and darkly robust expression of Woodford Reserve Kentucky Straight Bourbon Whiskey.
