You don't often hear of gins from Texas, but Treaty Oak have been distilling their Waterloo Gin since 2011. 

With a distinctly Texan flavour and attitude, Waterloo is best known for their Antique Gin, a barrel-aged liquid that many have described as one that will change your mind about gin. 

To discuss this further, we talk with Jamie Biel, Treaty Oak's director of science and sustainability about aged gin, botanicals, barrels and of course, sustainability.
