Cork

Cellar-Worthy: We use a top of the line, extra long, cork. Cork has a proven track record to allow a wine to evolve in the cellar. Engineered closures are attempting to replicate the oxygen transmission rate of a top of the line cork closure. In reality, it's unclear oxygen transmission is the defining metric for cork's success.
No Plastics & Adhesives: Natural corks are punched from whole slabs of cork bark. Artificial corks are made from petroleum products. Screwcaps use a plastic liner. Conglomerate corks use adhesives. Plastics and adhesives scalp flavors and aromas from wine and leach into the wine.
Biodegradable: Corks are natural & biodegradable.
Sustainable: Corks are renewable and can be sustainably harvested from cork trees. The bark is shaved off every 10-15 years, grows back, and the harvest repeats.
Footprint: The carbon footprint to produce cork is lower than screwcaps and 'petroleum plugs'.
Ecosystems: Proper farming of cork tree forests supports ecosystems of both animals and the communities that farm the trees.
TCA: By choosing a top quality longer cork, the incidence of TCA (2,4,6-trichloroanisole), the source of 'corked' wines, is reduced. Our cork manufacturer does extensive testing to reduce the incidence of TCA to <0.48%. Studies have indicated lower than the incidence of oxidized wines from excessive oxygen transmission from 'petroleum plugs' or failed seals in screw-caps.
