Bubble Up: The vintage lemon-lime soda that refuses to fade away

Bubble Up, a 1919 lemon-lime soda famous for its “kiss of lemon, kiss of lime,” has weathered ownership changes and bankruptcy and is now produced in limited quantities by Dad’s Root Beer. Fans seek its more natural ingredients and nostalgic glass-bottle packaging, with the premium soda selling in select stores and online for about $3.49 per 12-ounce bottle.
