Four Grain Barrel Strength bourbon is blended from three different MGP bourbon mash bills and aged in new American oak barrels, staves #4 char, heads #2 char. Mash Bill: 74% Corn, 16% Wheat, 7% Rye, 3% Malted Barley. Uncut, not chill-filtered, 57% ABV. Aged 4 to 6 years. Light brown straw color and light coating legs in the glass. Nose is floral vanilla oak, berry, and sweet malted cereal grain, with a whiff of spice in the background. Sweet grain and caramel corn in the mouth, with grassy rye spice, mint, and tannic oak. Mouthfeel is light and soft for a 57% bourbon. Finish is long: sweet and spicy, dry oak, and tart cherry. An ice cube softens the tannins and ethanol... maybe too much. Penelope has done a great job blending quality MGP whiskies (and being transparent about it)--so good that MGP recently acquired Penelope to blend and market their best barrels. Expect more quality batches to come.
