You do not need approval to substitute a wine, as long as your selection closely matches the descriptive benchmarks provided in the course materials—for example, a Sauvignon Blanc with notes of grass or herbs, or a Chardonnay showing butter and toast. The goal is to ensure you experience the key sensory markers the course is designed to teach.

The requirement for pre-approval only applies when deviating significantly from the recommended style. When in doubt, match the descriptors and you’re good to go.
