I agree that learning and improving one’s skills as a Barista requires hands-on training, but I have learned about 98% of everything I know from books, videos, or articles. When I finally was able to physically make espresso, I was mostly applying everything I learned and saw. BH has definitely been a source of a great majority of the knowledge I’ve acquired, so thanks a lot @MattPerger! So I have to believe that BH is already an online training course and by far the best one I’ve seen. I would still love to see more videos on here and maybe a formal training course if someone figures out how to do it well!
