Agglomerated cork, 47 mm long x 30 mm diameter: £78.00 per bag of 500
Sparkling wines, and some ciders and beers, need sealing to prevent the escape of CO2 gas from the bottle, thus preserving the pressure within the bottle. Champagne corks produced from natural cork are ideal for achieving this critical sealing capability. The usual diameter of a champagne cork is 30.5 mm, it is compressed down to 18 mm to fit into the bottle neck that it has to seal. Champagne corks are 'straight' before they are inserted into the bottle neck.
The final 'mushroom' shape is a result of the inserted portion of the cork being compressed in the bottle.

- Sparkling Wine corks
Each cork may be produced from several different types of natural cork. The main 'body' of the cork is made of agglomerated cork grains bonded together by approved binders.
Laminated to one or both ends of this 'body' may be natural cork discs which have high expansion characteristics.
Once inserted the cork expands; this expansion enables the cork to maintain a constant pressure against the glass bottle neck, preventing the CO2 gas from escaping.
Once pulled from the bottle the lower part of the cork expands, shaping itself into the 'mushroom'.
