These Winery Grade Corks are from Reference (formerly ALTEC)

In producing the superb Reference corks, natural cork is micro-fragmented, and most of the TCA bearing material, called lignin, is removed. The remaining pure cork flour is blended with a very small percentage of polymer, which enhances the natural elasticity and sealing properties of the cork. The result is a nearly 100% natural cork, perfect in shape and without defect or pores, superior in appearance and sealing quality, and with far lower TCA levels than other corks. They also recover shape immediately, permitting bottles to be placed on their sides at once.

Reference corks give you a perfect seal, and a superior appearance, every time!

Packaged in lots of 30 (perfect for a 6 gallon batch).
