GS25 and craft brewery Kabrew have launched a new radler called 'Bam-jjack Bam-jjack Tiny Chestnut Radler' for Family Month in May, using Korean chestnuts. Radler, a low-alcohol beverage mixing beer and soda, originates from the notion of 'cyclist' in German. The product features the traditional Korean flavor of chestnuts from Gongju, known for their rich taste. Emphasizing the 'Grandmillennial' (grandmother+millennial) trend, it blends traditional and modern sensibilities. With a low alcohol content of 4% and a 500ml size, it caters to both inexperienced drinkers and those who appreciate sweet and mild flavors. The name is cleverly inspired by the song 'Twinkle, Twinkle, Little Star.' This attempt reflects a contemporary take on local agricultural produce, hoping consumers enjoy the natural sweetness and Korean-grown ingredient charm.
