Yeast cap / bidule for champagne and cider bottles, 100 pcs

Under stopper / bidule used in cider and birch champagne production.

The yeast cap is placed in the bottle and then the cap is placed on the bottle before the 2nd fermentation in the bottle. During fermentation, a bottom surface is formed which is collected in the yeast cap in the neck of the bottle when the bottle is placed upside down. This simplifies the disgorgement process.

Can be used with 29 mm cap, item number 6037. Fits champagne / cider bottles with a mouthpiece design like regular beer and soda bottles.
