Another year, another Small Batch Release by master distiller Brent Elliot! Each year he blends different mash bill recipes to create a perfect bourbon. Rumor has it that this Four Roses 2019 Small Batch Release contains bourbon from a 21 year old bourbon made from their OBSV recipe! Nice! It’s the first time a 21 year old bourbon made it to this blend. The other recipes are 15 year OESK, 15 year OESV, and an 11 year OESV.
