Calls Tennessee whiskey ageing process ‘a crime’

McGregor discusses the merits of Tennessee whiskey with a fan on social media.

Thank you for this message. I recognise and respect Tennessee as solid whiskey distillers. Your methods of aging whiskey over 2 years, and in charred brand new barrels however, is a crime where I come from…Using corn, rye or wheat over grain is another conversation altogether. However, forgetting your choice of ingredients, whatever they are, you must let those ingredients age sufficiently. Allow the ingredients the correct time to age and allow them to age in barrels as old as Whiskey itself. They deserve time to reach their maximum flavor potential. We do not even know what American whiskey truly tastes like, because to gage a correct and fair opinion of it, it needs to be given the correct and fair time to age…Thank you for this message however, I appreciate it and it motivates me to continue. I respect your state, and your land, and I will be in Tennessee in the very near future. Along with all of the other major states of the United States of America. I will be there with my own Irish made Whiskey for you all.
