Phillips abandons cork for screw cap

Torqued-on pilfer-proof cap from England looks like conventional capsule, but twists open easily.

This closure, called torqued-on, pilfer-proof, is an adaptation of closures used for high-end spirits.

The wine varieties aren’t new, but just about everything about the package is at R.H. Phillips, Esparto, CA. Beginning in June, the winery began offering its R.H. Phillips’ 2003 vintage Chardonnay and Sauvignon Blanc and its 2002 vintage of Cabernet Sauvignon, Merlot, and Shiraz in a new high-shoulder glass bottle, designed by Phillips’ owner, John Giguiere, with the help of glassmaker Gallo Glass. A new slim front label from Landmark Label coordinates with the Phillips’ logo that’s molded into the shoulder of the glass bottle.

This is the first wine use of an unusual torqued-on pilfer-proof screw cap with its straight-sided capsule. Made by Global Cap in England, Phillips purchases the closures through distributor APMGlobal.

The winery is using a new CAS/8/8/360 Twin-Turret capper from Fowler Products that torques on the closure in one turret, then crimps the capsule under a bead in the second turret for a TE breakaway band. The plant also retrofitted its existing labeler with a special lug spotter so the label is applied in precise position each time.

As with other wineries using closures other than cork, Phillips primary motivation is the elimination of TCA, or cork taint, that is said to affect between 2% to 6% of all cork-finished bottles of wine. Some wineries have switched to roll-on pilfer-proof (ROPP) aluminum caps, others to synthetic corks.

“Our wines are estate-grown, handled with care in our estate winery and beautifully packaged as our seal of quality,” says John Giguiere. “And then we compromise it with cork taint. That doesn’t make sense to me.” Cork taint allows air into the bottle and can oxidize the wine, drastically changing its bouquet and flavor.

Borrowing a closure

“John was really interested in finding a screw cap that was a little different, one that didn’t look like a conventional roll-on aluminum cap that showed the threads,” says Lane Giguiere, co-owner of the vineyard.

The style of closure has been successfully used in the distilled spirits industry for well-known premium brands such as Cointreau and Tia Maria liqueurs. John Giguiere worked closely with Global Cap to create this version. The capsule top is lined with Saranex for its barrier properties.

The closure is essentially an injection-molded threaded sleeve that’s bonded to an aluminum capsule with adhesive. Within the first turret of the twin-turret capper, the cap is torqued onto the bottle with about 25 psi. Then, in the second eight-head turret, the capsule is perforated and crimped down over a glass bead to provide the tamper evidence.

The capsule measures 31.5 mm in diameter and 35 mm in length. “Global Cap had to customize one of its assembly lines to make the short capsule,” says Ken Lazzeroni, plant manager at R.H. Phillips. “The company had to modify equipment to accommodate the dimensions of our capsule. And the company worked closely with Fowler’s sister company, Zalkin, to make the heads for our capper.”
