response: I don't have the exact steps but wine tasters use ever changing words to describe the characteristics of wine like its flavors and aromas.
original_response: Typically the wine tasters will all sip the wine, then use an ever evolving system of terminology to describe the aromas, flavors, and characteristics of the wine.
history: Is it true Wine tasting is a delicate art? I'm unaware if it is or not, but there have been scientific blinding wine tastings that contradict wine tasting reliability. What do you mean by reliability? I can't say but the purpose of the blinding tastings is for wine scientists exploring the human olfactory system on things like identifying the compounds of a wine's aroma. How exactly is wine tasting done?
knowledge: Modern, professional wine tasters (such as sommeliers or buyers for retailers) use a constantly evolving specialized terminology which is used to describe the range of perceived flavors, aromas and general characteristics of a wine.
