Division 1 Definitions

F1Regulation 110/2008 sets minimum levels of volatile compounds other than ethanol and methanol for a series of spirit drinks (rum, spirits of viticultural origin, fruit spirits, etc.). For this series of drinks only, these levels are conventionally considered to be equivalent to the sum of the concentrations of:

1. 1..

   volatile acids expressed as acetic acid;

2. 2..

   aldehydes expressed as ethanal by the sum of ethanal (acetaldehyde) and the ethanal fraction contained in 1,1-diethoxyethane (acetal);

3. 3..

   the following higher alcohols: propan-1-ol, butan-1-ol, butan-2-ol, 2-methylpropan-1-ol, assayed by individual alcohol and 2-methylbutan-1-ol, and 3-methylbutan-1-ol assayed as individual alcohol or the sum of the two;

4. 4..

   ethyl acetate.

The following are the conventional methods for measuring volatile compounds:

• the volatile acids by means of volatile acidity,

• the aldehydes (ethanal and acetal), ethyl acetate and the alcohols by means of gas chromatography (GPC).
