About Deduvin

Deduvin was built for the moment at a tasting when the glass is in front of you and the names are on the table, and you want to work it out rather than be told. It is made in Stockholm by Henrik Blomberg, through his company Parallel Arc Industries, and it is free.

The wine knowledge inside it comes from the standard tasting literature, cross-checked against Systembolaget's taste descriptions for the wines people actually buy in Sweden, and tested against simulated beginners before any screen was drawn. When a wine's numbers change, the reason is written down. Deduvin uses no artificial intelligence at the table: the reasoning is a transparent calculation you can watch move on screen with every tap.

Deduvin sells no wine, advertises no wine, and is for adults of legal drinking age where they live. Taste, spit, and enjoy responsibly.

Deduvin's sibling is The Wine Profile, a wine quiz on grapes and regions with tasting notes you keep with friends.
