Boss — Wine Test Level 4

The hardest wine test you'll take. 1,000 questions, 27 subjects, no mercy.

Boss is exactly what it sounds like. This is the top of the mountain — 1,000 questions spanning 27 subjects, built for the group of people aiming at true mastery, not just competence.

Nothing here is introductory, and nothing is filler. Expect obscure regional detail, deep-cut producer and vintage knowledge, and the kind of questions that would make even confident tasters pause. This level was built for candidates preparing for the highest tiers of wine and sommelier certification — the material that separates "very knowledgeable" from "expert."

If you've already worked through New to Wine, Introductory, and Advanced and you're still hungry for more, Boss is the only place left to go. Consider yourself warned.

What's inside:

• 1,000 questions across 27 subjects — double the length of every other level
• The most difficult material in the entire quiz series
• Built for candidates targeting top-tier wine and sommelier certification
• Self-paced, saves your progress automatically across devices
