The Court of Master Sommeliers, Americas Introductory Course Workbook is an educational resource and guide to help focus students studies in preparation for and prior to attending the Introductory Course and Exam. This workbook is published by the Court of Master Sommeliers, Americas for this intent and purpose.
Highly recommend reading in full before taking the 2-day course to sit for your certification. Give yourself about 2 weeks of consistent reading time, as it is dense.
I took notes while reading beforehand, and also during the lectures, as the Master Somms follow the book content closely and add additional detailed information. I learned so much, and am planning on reading again in pre-prep for Certified Sommelier Level 2. Practice questions and prompts mirror the exam content and are helpful when studying.
The information is so superficial. Here are facts, remember them. I would have a much easier time remembering the information if there was more detail and explanation.
