Detailed Show Notes:

Amorim - 150-year history, largest cork company in the world, produces 5.5 billion stoppers per year, over 18,000 winery clients globally, most small

Sources cork from 1,000s of property owners, mainly in Portugal and Spain

Uses of cork: wine, footwear, fishing, aerospace, flooring, and sports

Differences between cork and other closures: technical, sustainability, and additional value add

Technical differences

Oxygen transfer rate (OTR) - plastic (lets in too much oxygen), screwcap (lets in too little), cork (“just right”)
Average cork has 800 million cells in it
TCA - “we have defeated TCA” - mitigated to the point where cork is now gaining market share
Consistency of corks - not an issue for technical stoppers (micro agglomerates, twin top), a technology used to help with natural corks

Sustainability - people, planet, profits

CO2 - a single cork can have up to 562 g CO2 sink per stopper
Cork harvesting one of the best paid agricultural jobs, ~€125-135 / day for three months/year
Cork forests are 1 of 36 hot spots for biodiversity in the world
Cork forests help prevent forest fires, regulate water cycles, and trees live 200-250 years
Corks are both compostable and recyclable (e.g., ReCORK America)

Additional value add = the happy sound of a cork popping

Of the 100 most sold brands in the US (data from Nielson), the average price of wine with cork is consistently higher than other closures

Closure market

19.5B closures per year
12.5B closed with cork (~70%)
1.8-1.9B single-use plastic stoppers

The price of cork ranges from €0.04 - 3.00 per cork

Screwcaps (the lowest price), plastic, cork
Cork can now sometimes undercut the price of plastic

Supply and demand for cork

2.2M hectares of cork forests in the Western Mediterranean - lots of trees to supply the current industry
It takes 43 years for a cork tree to supply cork for a wine closure -> new research with micro-irrigation is reducing the first harvest from 25 years to 10-12 years
