Cork extraction force

Extraction force

Extraction Force (EF), measured in decaNewtons, is the force required to extract a closure from a bottle. This is an important parameter for many reasons. Obtaining the EF value can help in evaluating the following:

a) A high EF value will indicate that the closure is too difficult to extract from the bottle. This may result in dissatisfied customers at best and at worst may lead to a broken bottle.

b) A low EF value will indicate that the closure is too loose in the bottle, leading to wine leakage and premature oxidation.

c) Comparison of EF values may assist in predictive variation in wine quality.
