Hey everyone, I am putting together a Barista 201 class that will be designed for baristas that are just above the beginner level. I want to include a lot of troubleshooting exercises both for milk and extraction. If anyone has ANY kind of feedback that they want to share that would be helpful. I am still in the brainstorming stage, so there are no bad ideas just ideas, so throw them out there.
