About

Flavor Alchemist

Features
Read full description

This app is a tool that changes the composition of wine and sake to enhance its flavor by utilizing specific wavelength patterns generated by sound and screen. A significant number of users have reported subjectively experiencing changes in the aroma and taste of the wine. In related research, professors from KAIST (Korea Advanced Institute of Science and Technology), including Professor Alan J. Buglass, the world's leading wine chemistry scholar, confirmed changes in composition and flavor through this app. (Refer to the paper in a world-renowned academic journal) The app allows users to experience changes in the flavor of wine and sake through free usage. This app is configured with two types of programs, Advanced and Fine, for red wine, white wine, and Japanese sake. The Advanced Program transforms mid-to-high-priced wine and sake (over $15) into beverages with a flavor value 5 to 10 times higher. The Fine Program targets low-priced wine and sake (under $15). The Fine Program not only elevates the flavor to a value 3 to 5 times higher but also reduces the physical discomfort often experienced after drinking low-priced wine. • For paid subscriptions, a coupon for 30 uses per month is provided. • The Advanced Program deducts 2 coupons per use, while the Fine Program deducts 1 coupon per use. How to Use: 1. Place a bottle of wine (750ml) within 15cm of the digital device and play the video (5 minutes). 2. For red wine only, allow a decanting time of 15 minutes or more. 3. For white wine and sake, pour into a glass and drink 1 to 2 minutes after the video playback ends. Tasting Comparison Method: 1. Open the bottle and pour one glass (the control sample). 2. Modify the wine remaining in the bottle (the treatment sample). 3. Taste the modified wine first, and then taste the wine poured earlier. 4. If you do not possess an absolute palate, it is recommended to follow the order above. * standard Apple Terms of Use (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
