Editor’s Note
This episode is part of The Sommpour D4 Audible Cheat-Sheet Series — a method-first revision sequence created for WSET Diploma candidates preparing for the D4 Sparkling Wines exam.
These episodes are designed for on-the-go listening and focus exclusively on distinction-grade, examinable detail from the WSET D4 specification. Each episode walks through one production method in the order the exam rewards, linking technical decisions directly to style, quality, and price.
This series is intended to complement, not replace:
the D4 Tasting episode (how to read the glass), and
the D4 Theory playbook episode (how to answer the exam).
Use these cheat sheets in the final weeks of preparation, during commutes or short study windows, to reinforce structure, sequencing, and recall under time pressure.
