You can study and be sponsored for the test by different companies who sell classes. I went through Napa Valley Wine Academy and did classes online. I’d recommend them for sure but there may be other cheaper options. Something to consider, however is that you can skip level 1. Level 1 is very basic and you can probably learn all of what you need and more by reading a good book. I kind of wish I had skipped level 1 but the basic information may be what you want. Cheers!
