I have a couple of questions/comments about your experiment.
But first off, thanks for posting this video. I enjoyed it.
How long did the coffee rest after roasting? It seems to me that you can't get full extraction until 4 to 5 days of rest. I guess this would affect all of the brew methods, but it also might make the french press a little more viable.
Also, in regards to the press, did you stir after the blooming?
I use a insulated press and preheat all of the parts including the spoon and I seem to get good results.
One last thing. Does a longer brew time in a french press cause unwanted flavors after a certain amount of time? If so, how long?
Thinking a simple and quite 3 min. sand egg timer might work nice for the Clever dripper
[quote comment=""]Isn't another alternative for the dripper to modify in a stopper so that you could effectively stall infusion time to the desired length? Especially with the two-hole dripper it would be pretty simple to add some rubber stoppers that could be pulled out at the three minute mark. I guess I am lamenting just having ordered six drippers for our shop... do you see any problem with modifying them in that way?[/quote]
I am sure there is a way ... i just can't imagine how you plug up the holes and release them easily while brewing. Let me know if you figure something out -Tom

The weight ration was 22 grams coffee to 361 grams water. I will check but I believe it to be near 11 oz of water. We'll keep modifying the variables to get some better results. The main point was to realize the dangers of underextraction and low temp brewing in a French Press, and perhaps of overextraction in a Clever Coffee Dripper, as well as the results from the Beehouse Dripper which I must admit were not as bad as expected given that in brewed in 1:30, including blooming time!
That was really cool to see for so many reasons. When you have it dialed in with your ExtractMojo and software be sure and share the results of weighed water gram no's (was hard to decipher the amount of water weight) with 22 grams of coffee and as good a description of grind as can be described.
There are so many variables to play with to hone it in--it would be cool to hear if it reflected in the cup as positively as hoped for. A moment of respect for George Howell...
I tried weighing water for a FP this AM and noticed how significantly it can vary with a measuring cup at say 10oz--great tip.
Interesting you chose not to vary the grind for the Aero vs CCD--is that the grind you normally choose? If not--was it to be more consistent for the experiment?
You also have some newly reflected ideas on FP steep times compared to your FP printed methods on this site and grinding coarser it seems than you advise..Your 2 min steep on the Aero was a bit of a surprise as well but you say to try all variables.
Show more as you keep learning!!
For those of us that can't come to classes these videos are an invaluable resource! Thanks for taking the time and please continue to do them. I LOVE my new CCD's (having used either Melitta or a French press before). This is by far the best taste and mouthfeel I've ever made with my coffee - smooth, rich, dare I say buttery...I'm in love all over again.
Still working on grind, etc. but even so.... wow!
Thanks for the vid, Tom.
We've been using those two Clever Coffee Drippers that you gave me at the new shop, and the coffees coming from them have been badass! Obviously, we've ordered a bunch more. Also, we've been using the CCD on a scale as well, using it to weigh the water.
I've also got an ExtractMojo on the way. I have many other experiments to play with on the e.m. In the mean time, while I'm a big believer in the CCD, I don't think that you're giving the french press a fair shot. I'll do some of my own testing, but I think there are some simple ways to make better french presses.
Anyway, more experiments to come. Maybe we'll make some vids. Thanks for everything!
