A superior solution for premium, boutique and luxury wines

Nomacorc’s global research programs have revealed that oxygen through the closure directly affects the chemical and sensory development of wine. Using this knowledge, Nomacorc developed a portfolio of closures, the Select® Series, which are winemaking tools engineered to provide specific solutions for the complex oxygen requirements in different wines.

Nomacorc Select® Bio Series


A sustainable solution for premium age-worthy wines and natural, organic and environmentally-minded wineries, Nomacorc is proud to introduce the world’s first zero carbon footprint wine closure, Select Bio.

Select Bio is made using renewable, plant-based biopolymers derived from sugar cane. Like all Nomacorc products, Select Bio corks are fully recyclable.

Which Select Series Closure is Best for Your Wine?

Certain wines need different levels of oxygen to breathe and develop. Combining research, winemaking conditions and consumption windows, Nomacorc’s NomaSelector software can determine which Select Series closure will help wine perform and deliver optimally. By choosing an oxygen ingress level with a Select Series closure, winemakers can shape how their wine tastes and smells when opened by the consumer.

From grape variety to winemaking conditions to storage, Nomacorc's NomaSelector tool uses a proprietary algorithm to guide winemakers in determining which Select Series will help their wine perform at its best.
