Kentucky-based Buffalo Trace Distillery is all set to roll out the eighth release of Single Oak Project Bourbon by the end of February 2013.

All the bourbons in the batch were aged in Warehouse K at 105 proof and seasoned for 12 months to focus on the recipe, wood grain size, and tree cut, reported whiskymag.com.

The Single Oak Project is part of research project started by the distillery in 1999 by hand picking 96 trees with different wood grains and then doubled them to yield 192 sections.

Each of these sections was used to create 192 barrels in which the bourbon was aged and released after every three months from 2011 to 2015, until all the barrels are released.

Bourbon marketing director Kris Comstock told the website that this release will attract many bourbon drinkers since fans contend 105 entry proof to be better.

"Bourbon drinkers can taste and decide if they like wheated bourbon or rye recipe bourbon better at the 105 entry proof," added Comstock.

Halfway through the project, barrel number 106 and 97 have been fighting hard for the top spot.

"But with two more years to go, any of these bourbons still stand a chance to be declared the winner," said Comstock.

Each case in the eighth release contains 12 bottles, collected from 12 barrels numbered 27, 28, 59, 60, 91, 92, 123, 124, 155, 156, 187 and 188.

All releases will be available in 375ml bottle format at a price of $46.35.
