The Home Barista's Guide to Espresso advocates ending the extraction by color, meaning blonding of the stream of espresso. But does everyone agree what "blond" means? To test, I created a video of an ordinary espresso extraction with markers A.. B.. C.. through H.

When would you cut off this espresso extraction?

Hmmm. 6 votes and 6 different answers right now.... goes to show you that it's different strokes for different folks. I voted G, but F looked like it was about there.

I voted F because it looked like the blonding started to show in a few areas at that point, but it still looked pretty decent even at H. I've had worse and still drank it.

Better lighting probably would have helped.

I voted for F although it was hard to decide.
my 2 cents are that the beans as well as the type of grinder strongly influence the sharpness of the blonding point. When I changed from the MDF to the K-10 the blonding point became much more fuzzy. When using 'older' beans (already a week out of roast) the blonding point seems to become more distinct. Also when using a lower dose the blonding point is easier to detect than with a high dose.

voted F, though maybe it could be E as well

EDIT: where I would stop it. :D

I think with spouted portafilter it would be another good quiz!

I went for G (F was close, but decided G was closer!)... Oh well, different strokes for different folks! :D

I went for D. I usually end the extraction when the "crema cone" volume drops significantly, which it seems to toward the very end of D.

I had a tough time deciding between D and E (either could apply for me)
Anyways....I went conservatively with D

i went F, but I could see going to G. The video is a little dark on my screen here at work as well.

I'm so used to spouts that I might be able to tell better on a spouted pf.
