The wine-producing sector and the local institutions are interested
in the development of specific sensory methods to be applied
by expert panels in order to control and improve the quality of RA
wines, emphasizing their typical characteristics.
The objective of this work is to explain the method developed to
evaluate and score the sensory quality of young red wines from RA.
This method was accredited in February 2008 (www.enac.es).
According to the purpose of each step, wines were evaluated in
the group room or in a room with seven booths equipped with computer
terminals. In the booth room, both temperature (21 ± 2 C)
and relative humidity (60 ± 20%) were controlled. Olfactory and
gustatory evaluation was carried out firstly under the weak light
provided by the computer screen to avoid any colour bias. Appearance
evaluation was carried out by using additional glasses and under
lighting similar to daylight (colour temperature very close to
6500 K and chromatic rendering index higher than 90).
Through the method development wines were scored in paper
cards. Once the definitive score card was defined, data from wines
evaluated in booths were collected with FIZZ software (Biosystèmes,
Couternon, Version 2.10 A).
