Where can I read more about wines? I kind of like this culture and I want to learn more about it. Share good links, please. 

Thisdayinwinehistory is the obvious answer here. So go for it. I can share one article here, so you will decide whether you want it or not. Check this out https://thisdayinwinehistory.com/brunello-di-montalcino-a-tuscan-splendour/ . This is a good as it gets when it comes to websites that cover wine.
