Added note: I completely forgot to mention that any differences in taste could also be due to differences in temperature. It's possible that pouring at a very high point, such as 18", could cool the coffee down more than the others. There is a point in coffee temperature as it drops where you can perceive more of the flavor more clearly. This may have effected my results! Something to keep in mind
Try repeating this experiment, but vary the pour order. Instead of pouring 0", 10", 18", repeat it at 18", 0", 10", Then do it again with 10", 18", 0". Then pour 3 cups at 18", 3 cups at 10" and 3 cups at 0" to see if each cup at each level tastes the same. My reasoning is that the coffee in the pot may not be homogeneous from top to bottom and that pour order may influence flavor as much as aeration. Just a thought...
Hi Eldric! This would certainly help haha. I appreciate you stopping by to watch! I hope you enjoyed my (definitely not conclusive) test of aeration. Would love to chat with you some time at Harken and maybe even try a side by side. There's probably more to be discovered here, and I know you've done a decent amount of work on the topic. Wish you all the best!

My great-grandmother from Germany did a high pour for the flavor.
First time heard about it. Interesting topic!
Glad you liked it!
What do you think? Can you pour your coffee 18 inches above the cup in the morning?

It's possible I suppose! Depending if you stirred it up with a spoon though, I'd imagine any differences would be negligible. Could be wrong though
Interesting video. I love science and all things coffee ☕ . I'll try this weekend just for fun. I'm sure my wife will ask what I'm doing now 😒
Haha that will be a fun one to explain Don!!
Would recommend trying a wine aerator. No risk of spilling everywhere!
