I am not going to comment on any particular posts, but I do want to interject my view which was informed by being part of tasting panels for many years.
Taste and aroma are objective in that you can test an individual for their JND {just noticeable difference: ie measure how much of a compound needs to be present for them o ‘just notice it’ in a statistically reliable amount.
This is typically done in triad testing where you have a trio of samples, one or two adulterated with the compound in question. The ‘tester’ needs to identify the adulterated examples a specific proportion of times to be rated as having a JND for that compound. Since it usually takes more than 3 trials to establish this, and it needs to be done at least for the specific compounds a tester needs to consider, it is time-consuming, incredibly tedious.
It is something one does when one has a lot of time on their hands, and belongs to a nerd wine-tasting group. If you did not have a light box to rate the colors of wines in one order, check smells in another, taste in yet a third, and finally enjoy the glass as a whole is a 4th order, you have no idea. Half our time was spent on statistics. And the other half was spent trying to figure out which was which on your cscore sheets. The wine tasting itself was unimportant.
That’s what happens when one tastes with several engineers from the aerospace industry at a time when one did not have a girlfriend in college.
But here is the point, this rigorous methodology has specific results. Like order of placement had a strong statistical effect on ranking. If we had 8 zinfandels, and 7 were high alcohol a lower alcohol example scored higher when tasted after the high alcohol ones and lower before. The descriptors changed. And there was no way for our methods to untangle our bias. What wound up happening was we put the bottles out in bags and just grabbed what we liked to go with our sandwiches or pizza. And the empty bottle test yielded another set of results.
Technical, objective tasting is great for winemakers. They need to be able to ID the various compounds in their wines. beers, booze for stability reasons at least. They need the sensory input and lab results both.
On the other hand, the empty bottle test relies on nothing but your subjective tastes but it also yields more info on pleasure than anything.
I mean we can look at a steak and measure how even its color is from top to bottom when sliced. I am sure that sous vide will win and char-grilled will fare poorly. But I love the feel of the char {char, not sear} and if MOST of the steak is medium rare, a little well-done ring is a small price to pay for the char flavor. In my opinion. You are entitled to your obviously wrong opinion. I am nothing if not magnanimous.
