River to Summit was held at Riverport Park Minokamo on November 4th and 5th, 2023, and Hayashi Yukai Laboratory also had a booth. We sold it for 200 yen per cup only at the event, and more than 300 people in total tried it. We will upload a video of our impressions at a later date. The weather was good on the day, and Minamo-kun also enjoyed the cola, saying it was delicious. Fairtrade cola was popular after walking and sauna, Hortensia, which changes color when lemon is added to it for women, and ACACOLA, which is caffeine-free, additive-free and easy to drink for children.
