Why should taste be subjective when sight isn't? - Page 5

That depends... did the "chicks" you picked up have large Adams apples and speak in deep tones? :wink:

I know this isn't a wine board, but . . .

HB wrote:We scored drinks on a scale of 0 to 6.0. Each judge scored their drink independently and it was unusual for them to differ by more than 0.5 point . . . .

My point is that good sensory judges can distinguish between their personal preference and a well-explained standard of an exceptional espresso. Not that it's easy to agree on that definition, but evidently it's not impossible.

Dan, wines are generally scored on a (UC Davis modified) 20-point scale, or a (Robert Parker/Wine Spectator) 100-point scale. Either way, it's next to impossible to get less than 50% -- i.e.: the scale is either 10.0-20.0, or 51-100.

When I was taking wine classes at UC Davis back in the 1970s, professors there demonstrated through a series of experiments that, using the UC 20-point scale, the human tongue had a "built-in" error of +/- 1.5. That is to say, the difference between a wine that received a score of 15.0 and one that scored 16.5 was statistically insignificant.

Thus the question left unanswered by Robert Parker and the people at the Wine Spectator: how do you tell the difference between a wine that scores an "89" and one that scores a "90"?

The first thing you say is exactly what I've been saying: taste can be trained to meet common standards, and such common standards are desirable for a functioning group of coffee lovers.

I'm sorry you are offended that I characterized you thinking that you disagree with me as "mesmerism." I didn't mean it personally.

I meant that our culture comes ready made with common modes of thought and speech about taste. Ironically enough, this common mode of thinking is a quasi-religious and completely superstitious awe at the power and glory of ones "individual and subjective" tastes and preferences. To say that "I did this because I like doing it" is the same as saying "sleeping pills have a dormative property," that is, it says nothing at all.

This is why I call "because I like it" taste explanations mesmerism. It's a way of stopping rational thought about taste, rather than starting it.

I've come to realize a high correlation between yumminess-to-me and *extremely* objective quality. A deobfuscation of my wiring and beans has worked wonders that I wouldn't have predicted. That's my current standing.

GB wrote:A very interesting thread. It is my understanding that people being taught how to taste wine compare their taste experience against standardized vials of aromas . . . Does such kit exist for coffee tasting? If not maybe something like this is needed and would help?

The kit does NOT teach people how to taste, Geoffery, but rather it "assists" in helping to identify certain components in wine and in standardizing one's vocabulary. Saying "apple" isn't as helpful as saying "Golden Delicious apple" or "baked apple," and so on; saying "nutty" isn't as much help in describing a wine's taste as saying "hazelnut," or "almond," etc.

Le Nez du Vin is at its most helpful when it comes to identifying flaws in a wine -- ethyl acetate, volatile acidity, mercaptans, Brettanomyces, hydrogen sulfide, and so on.

Since the only "flaws" in coffee are things like stale beans, shots pulled at too high a temperature, etc., I am not sure if a "Le Nez du Café" would be as effective . . .

Cheers,
Jason

P.S. If you want to know how to make a "Le Nez du Vin," send me a PM. This is, after all, a coffee board. :wink:

another_jim wrote:I recommend basing your taste in coffee on its terroir, and on the care that went into growing, prepping, roasting and preparing it. That is an objective standard for taste in coffee. Choosing to use it consistently is up to you.


I can buy-in to this, but it describes a lifetime of learning. To transform taste sensations into meaningful interpretations of terroir, care in handling, etc. is very difficult. For example, I have a bit of experience with roasting my own coffee. This experience has given me the ability to know when I get coffee from my local roaster that has a roasting flaw (like a stalled roast). How do I taste the care in handling, when I have no idea how it was handled, and without an expectation of everything that poor handling comprises or tastes like?

Keeping these standards objective through the transformation from red cherry to the taste in one's mouth is the whole trick, as one needs standards against which to benchmark. I would love to have some shortcuts through this process - similar to what Jason refers to with Le Nez du Vin, only in descriptive form.

Why is that? Diversity of preferences is not good? Conformity in taste preference assists in the survival of the group and is therefore "desirable"? The thread that this was split from seemed to me to be a guy expressing some slightly odd ideas and (about half the time) getting burned for people thinking he was trying to make people believe what he said. Are we really expected to believe everything that is written here? Someone even said that the reaction to him was necessary because people might read the thread and believe the OP. Sounded to me like a certain amount of heretic burning. There are separate communities of people here on the subject of tamping, on lever machines, even on the amount of technical messing about that is desirable in making a cup of coffee, and memberships in these overlap and vary over time. Why can't there be different communities around taste?

Elsewhere in the thread:

This reads like standards trumping personal preferences, and that makes me nervous, whose preferences are being encoded in the standards?

That depends... are we talking about Pat? or Chris? :?

Re the topic at hand I don't have anything useful to add about taste, as my palate is about as educated as a palette (the kind made from rough wood). But I was glad to see King Seven's reference to Mark Rothko, as it felt like a lopsighted analogy between taste and sight when the latter was reduced to the ability to distinguish between red and green.

Again, to say "I like it because of MY preferences," is to say "thou shalt not question what I do." We have a sort of social contract that when we work, we hold ourselves responsible for the consequences of our actions and decisions; but when we are shopping, eating, etc, we don't. That's fine by me. In fact, if I had my druthers, I'd rather never be held responsible, credited, praised or blamed for anything at all.

But that is not what I'm talking about. So please don't accuse me me being some sort of grinch trying to take away people's Adam Smith given right to like whatever they please.

Question: Bill likes Starbucks better than Dunkin Donuts, Sally the reverse. How much are their lives improved by being able to get the one they want?
Answer: A bit, but nothing dramatic.

Question Now Sally learns about coffee, she knows what she is drinking, enjoys expensive auction coffees more than others, can taste the flaws in roasting etc. Now, how much more than Bill does she get out of drinking any coffee, good or bad, Starbucks or DD. Just a bit, or maybe a whole lot?
Answer: You decide

I strive to be objective in my taste to get more pleasure out of my coffee, not to take it away.
