WoodfordReserveMaster’sCollectionHistoricBarrelEntryBourbonWhiskey(700ml)

Sans The 18th Woodford Reserve Master’s Collection release continues to explore a particular aspect of whiskey making. This year’s is created from a mashbill of 72% corn, 18% rye and 10% malted barley and bottled at 45.2% Alc./Vol. New-make went into the barrel at 100 proof. The entry proof plays an important role in the maturation process, and the standard for 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, and after the repeal of Prohibition, barrel entry proof levels began to increase. Why is this significant?
