My number one tip for being successful on the Champagne Master exam is to read and re-read the manual. I read through it around 15 times (possibly more) and it is the best piece of advice. If I could go back I would have read it at least three times before starting the webinars. When it comes to what to study, focus on key dates, numbers, french words (there will be a handful of words that you should know and you will likely be tested on), and key concepts including yields, grapes, and champagne styles. The online classroom has sample questions that you can focus on to determine the style of the multiple choice questions. I wrote out all of these questions in a document and highlighted the answers to review. Here is an example of what I did:
Which winemaking advancement did not occur in the 1600s?
Cork was reintroduced as a seal
The pupitre was developed to assist in riddling - 1840
England developed a method to make strong glass
Bottles were crafted with uniform neck openings.
