Before you answer, read what Tablas Creek Vineyard’s General Manager Jason Haas has to say about each. In fact, it’s a question he is continually asked. Just recently, he had his third discussion in a week with a consumer as to why the winery bottles some of its wines in Stelvin screw caps and others with natural cork.

The consumer inquired whether it was because wines under screw cap were less expensive than those with a cork closure.

They're not.
