Actor Jung Hae-in appeared on the YouTube channel 'Yuin Radio' on the 12th and revealed his hidden side as a whiskey enthusiast. When asked about his personal interest where he could demonstrate the most in-depth knowledge, Jung chose 'whiskey' and expressed his exceptional affection for it, saying, "I was very interested, so I studied it a bit. The aromas are so good, the flavors are good, and the atmosphere is truly great." Demonstrating professional expertise, Jung clearly knows the differences between single malt, blended, and bourbon whiskeys, stating, "Even in blind tastings, these three have completely different ingredients, aromas, and flavors, so I can absolutely tell them apart." He further proved himself a true whiskey connoisseur by admitting he even enjoys peated whiskey, known for its divisive disinfectant-like note among enthusiasts. When asked to recommend a whiskey for beginners, Jung advised, "I would like people not to think of it as difficult. I recommend starting with Balvenie, which is the least divisive and can be enjoyed smoothly." When questioned about what he would do with a month of freedom as a person rather than as an actor, Jung's passion for whiskey continued as he expressed his desire to return to Scottish whiskey distilleries and visit ones he hasn't explored yet.
