Cork Supply founder & CEO Jochen Michalski joins Billy Galanko to unpack 40+ years of cork innovation, how the industry tackled TCA (cork taint), why oxygen transmission matters, and when to choose natural, technical, synthetic, or screwcap. Jochen explains Legacy (Cork Supply’s premium natural cork) and its X100 imaging, AI-assisted electromagnetic scanning that screens individual corks for TCA and internal structural risks to reduce bottle-to-bottle variation. We also dig into manufacturing, QC, climate impacts on cork forests, and why consumers still equate cork with quality.

What you’ll learn

• How TCA went from industry crisis to near-zero—and what “1 ppt” really means.
• Natural vs. technical corks: ideal use-cases and aging implications.
• Why oxygen control is central to wine development and consistency.
• How X100 imaging + sensory panels power Legacy’s screening.
• How bottle neck shapes, cork length, and bottling lines affect sealing.
• Forestry, climate, and the future of sustainable cork.
