Je pense que c'est possiblement en bonne partie l'actuel contenant, i.e. si tu les verses dans le même verre, bien de la différence va disparaitre.
Les expériences a l'aveugle sont incapables de montrer une différence je pense:
https://www.mdpi.com/2306-5710/2/4/25In the main experiment, 151 participants at the 2016 Edinburgh Science Festival were served a special ‘craft beer’ in a plastic cup. The beer was either poured from a bottle or can (a between-participants experimental design was used). The participants were encouraged to pick up the packaging in order to inspect the label before tasting the beer. The participants rated the perceived taste, quality, and freshness of the beer, as well as their likelihood of purchase, and estimated the price. All of the beer came from the same batch (specifically a Session IPA from Barney’s Brewery in Edinburgh). None of the participants were familiar with this particular craft brew. Nevertheless, those who evaluated the beer from the bottle rated it as tasting better than those who rated the beer served from the can. Having demonstrated such a perceptual difference (in terms of taste), we then went on to investigate whether people would prefer one packaging format over the other when the beer from bottle and can was served blind to a new group of participants (i.e., when the participants did not know the packaging material). The participants in this control study (n = 29) were asked which beer they preferred. Alternatively, they could state that the two samples tasted the same. No sign of a consistent preference was obtained under such blind tasting conditions
et ce genre d'expérience semble montrer aussi un effet psychologique possible, les gens préfères la bouteilles on vont trouver la bière meilleur si ils voient qu'elle vient d'une bouteille. C'est une question relativement étudié par l'industrie, parce que la bouteille de verre est bien plus compliqué et chère, mais continue d'être populaire.
Si on se fit au monde du vin ou de l'audio, une chose est certaines on ne peu pas se fier a ce que les gens disent, couper une banane en deux et en présenter une moitié comme bio et l'autre comme normal avec un beau petit speech, bien des gens vont trouver une moitié meilleur que l'autre, je dois être terrible là dessus.
