The Inter­na­tional Olive Coun­cil (IOC) val­i­dated a red tast­ing glass as an alter­na­tive to the com­mon cobalt blue cup cur­rently used by those who per­form sen­so­r­ial analy­ses of olive oils.

The new tool had been pre­sented by rep­re­sen­ta­tives of the Uni­ver­sity of Jaén and the Span­ish com­pany Elaia Zait to the com­mit­tee of experts of the Inter­na­tional Olive Coun­cil, who then stated that it meets the stan­dards adopted by the Orga­ni­za­tion for sen­sory analy­ses of olive oils.

This is the result of an inno­va­tion project that we have car­ried out at the Uni­ver­sity of Jaén for the com­pany Elaia Zait,” José J. Gaforio, who devel­oped the new glass with Miguel Ángel Rubio and Alfonso Martínez, told Olive Oil Times. The IOC’s val­i­da­tion of the red gar­net tast­ing glass is an impor­tant mile­stone for the olive oil sec­tor as it rep­re­sents an inno­va­tion that improves the organolep­tic analy­sis of vir­gin olive oils. Its main char­ac­ter­is­tic is that it totally neu­tral­izes the color of the oils, avoid­ing biases in the analy­sis.”

This shade of red was selected for its abil­ity to make olive oil appear col­or­less from the out­side, said the IOC, which high­lights the com­pli­ance with stan­dard COI/T.20/Doc. No. 5 of the Method for the Organolep­tic Assess­ment of Olive Oil: Made of dark-col­ored glass to pre­vent the taster from per­ceiv­ing the color of the oil, thus elim­i­nat­ing any prej­u­dices and imped­ing the pos­si­ble for­ma­tion of biases or ten­den­cies that might affect the objec­tive­ness of the deter­mi­na­tion.”

The color red, how­ever, has also been found to hin­der moti­va­tion and the abil­ity to think, and trig­ger strong, often neg­a­tive psy­cho­log­i­cal responses, noted Olive Oil Times pub­lisher Cur­tis Cord in a tweeted response to the cre­ators of the new glass in 2017.


What’s worse: a pleas­ing blue ves­sel that not entirely con­ceals the color of an oil sam­ple, or a glass that’s red — nature’s cue for dan­ger, the sym­bolic color of warn­ing signs and poi­son labels?” Cord asked.

Red is per­haps the most manip­u­la­tive color, influ­enc­ing every­thing from your behav­ior in the work­place to your love life,” the BBC’s David Robin­son wrote in an arti­cle that under­scored the power of red to influ­ence how we per­ceive things.

Andrew Elliot at the Uni­ver­sity of Rochester in New York found that peo­ple per­formed worse on cog­ni­tive tests if they were given to the par­tic­i­pant in a red cover slip,” the BBC reported.

And, as Juliet Zhu, a Uni­ver­sity of British Colum­bia psy­chol­o­gist noted, Think about red, and what comes to mind: stop­lights, stop signs, dan­ger, ambu­lances. Blue is the color of the sky, the ocean, safety. When their envi­ron­ment is safe, peo­ple are more explo­rative.”
