First of all, let me wish you all a very Merry Christmas and a Happy New Year! Better late than never
It's so nice that we still have books that teach us anything and especially those books aimed at improving our coffee preparing skills. A good book will always serve as a good illsutrator what to do and not to do when brewing coffee. And I'd like to share a book with you that helped me a lot when I was young and unexperienced about this beverage. Hope it helps you too
