Yes, it does! Jim, this was a wonderful experiment. Congratulations."Experiment soothes the mind" -- Francis Bacon
If nothing else, your experiment showed that one can save ~2.5% on coffee costs by using the Elektra over the DC.We used four coffees, the Sidamo Bonko SO at 14.5 grams on the Elektras and 14.8 grams on the DC at normale pours. Intelligentsia's Black Cat at 15.1 for the Elektra's and 15.5 for the DC at ristretto pours, Metropolis's Redline at 14 .7 for the Elektra and 15 for the DC, and a Guatemal Oriente DP at 15.6 for the Elektras and 16 for the DC
It's been said many times, but past a certain level, it seems like the better machines don't necessarily produce better espresso, but they sure make it easier. IIRC, in the Beat the Robur testing the samples were vigorously WDT'd. That was the equalizer. Without WDT, I imagine the Robur would have been a clear winner. Or do I remember wrong?We talk a lot about how different machines are. But those of us who have done blind taste testing know that once the machines and coffees are good quality, this is about very small differences indeed. The formal Titan grinder tests were very close to a wash. The informal "beat the Robur" tests were statistically insignificant and relatively minuscule except for a few ill favored grinders. And that was just about the clearest of the taste tests. Most of the other stuff has been even closer to no difference.
The simple act of setting up a test like this forces one to squeeze consistent performance out of each tested item before the testing starts. That usually eliminates almost all the things that were contributing to the initial ideas about dramatic differences.
I don't know what "hinky" means, and I don't understand this paragraph. Could you please explain?This test was done with the OPV defeated (turned all the way in to max pressure). I'm fairly sure my OPV was hinky, but given the huge improvement in shot quality I got when doing this, I doubt the 9.5 bar setting the machine is delivered at in the US is even remotely close to right.
The final conclusion goes to Ken Fox
As always, Dr Fox rules.
