heh, this is getting to be like a bad Rocky movie where each of us take turns landing haymakers :mrgreen::mrgreen::mrgreen:
The test does answer the question and it does so in more ways than one. First, as you note, perhaps only a very small percentage of people would be able to tell the difference between all of the woods or some of them. This would answer the technical question of whether or not the woods gave off different flavors. Since at least SOME people could tell the difference, the answer would be "yes".
As you noted, there's a practical component as well. If the vast majority couldn't taste a difference between the woods, then for "practical purposes", "wood is wood, smoke is smoke". Again, question answered.
In reading your responses and thinking about them, it dawned on me that the test in question would tell us even more once you go in and start sifting the data. Forgive me here as it's been quite some time since I sat through a Marketing or Stats class, so I'm more than a bit rusty and not up on the correct terminology. But, as with any kind of poll/test, the more tests/results the better. As the data set increases, you can begin to make more and more inferences from that data.
On one hand, you can start dividing people into groups based on their ability to differentiate. On one side you'd have a group who can't tell a difference between any of the woods. On the other end of the spectrum, those who were able to differentiate all the woods. In the middle groups you'd have people of various levels of success.
From that data, you could then start to compare one species of wood to others. Or even groups of woods to other groups. For example, the data might indicate that X % of people have no trouble distinguishing between peach and hickory. Or that y% can taste a difference between pecan and apple.
Digging further into the results, it might turn out that certain woods are really close in flavor and difficult to distinguish between one or the other.
Will address below...
I disagree here. Sure, some might grab whatever is on sale, but it's possible that while they might taste a difference, they aren't overly partial to one or the other, so they grab what is cheapest.
Cool.
I haven't tried any kind of testing with all the woods, but I can tell you for sure that a couple of friends and family members have no trouble distinguishing between the smell of burning hickory and apple or the taste.
Again with the matching. I'm not asking them to match and matching or not matching doesn't accurately test the question. hell, I can't smell cheeses then taste cheeses and correctly match which smell went with which taste. But I sure can taste some Mozz and then some Jack and tell you that they are different cheeses.
Simple straight forward test. here are two pieces of meat that have been smoked. Do they taste the same or do they taste different ? <cleanse palate> here are two more, same or different ? <cleanse palate> Here are two more, same or different? <cleanse palate> Here are yet two more, same or different ? ...
