Woodford Reserve is to expand distribution of its limited production Master's Collection from the beginning of this month. The first whiskey released in the collection, Woodford Reserve Four Grain Bourbon, is the only Bourbon in the world to be distilled solely in copper pot stills, owner Brown-Forman claims.

Four Grain was released in Kentucky last autumn, but this roll-out marks the first time it is available for sale in 16 states; California, Colorado, Illinois, Indiana, Florida, Georgia, Massachusetts, Michigan, Missouri, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas and Virginia. Kentucky will also receive a second supply of Four Grain during the release.

The Bourbon, bottled at a 92.4 proof and individually numbered, will retail at US$79.99 for a 750ml bottle in major metro markets. Only 750 cases are available.

"We were overwhelmed with the response Four Grain received in Kentucky," said Wayne Rose, brand director of Woodford Reserve. "We knew we had a pretty special whiskey on our hands, but we never anticipated it selling out in a matter of days. This allocation will likely sell just as quickly, with one small bottling next year before Four Grain disappears forever."
