Gavin and Torsten explored the complexities of whiskey production, particularly focusing on the influence of wood and climate on the aging process. They discussed how different environments, like the hot and humid conditions at Kavalan in Taiwan and the cold, isolated setting of Islay in Scotland, impart unique characteristics to the whiskey. They underscored the importance of the relationship between the whiskey and the wood, noting that not every barrel is suitable for every whiskey. Their conversation highlighted the intricate factors that contribute to each whiskey's distinct flavor. They also compared an older Highland Park 15 with a newer one, noting significant differences in flavor profiles, with Torsten pointing out variations due to production speed and demand.
