If you want to teach yourself wine, start by reading about the basics of wine, such as the different grape varieties, wine regions, and how to taste wine. Begin by trying different wines, taking notes on what you like and dislike, and identifying the characteristics you taste. Experiment with food pairings, and try attending wine tastings and events to learn from experts and other enthusiasts. Keep learning and expanding your knowledge by exploring new wines and regions, and don’t be afraid to ask questions or seek guidance from knowledgeable wine professionals.
