BubbaDude Said:

Sour is under-extracted, bitter is over extracted. Which ever way your shot is off, adjust duration and temperature accordingly.

19g fits the basket best. If you don't fill it enough, you can't tamp it correctly because of the shape of the basket.

Weight is a better guide than volume because of the froth.

The ability to dial-in the precise brew temp is the BDB's killer feature, don't forget to use it.

Posted December 5, 2012 link

so you recommend 19g instead of the 18g?
froth here you mean the crema? im clues in weighting the shot, how? or perhaps i should just check the end of the crema to hit the 2oz line and not to stop the shot with the top of the crema hitting the 2oz line

i want to eliminate other factors, i will try to do the temp surf with the exisiting setup that i have, i'll see if it can cure it, this slipped my mind as i was pulling my hair, thanks for the reminder

You can weigh your shots with a small scale. Some shots have more crema than others at a given volume.

so its not necessary to check the 2oz shot using the line, it more of weight paired with shot time so to speak

Right, the crema volume is simply an indication of the age of your roast and the nature of your beans.

aha, ok i will take that, i will weight now, yes ive noticed the crema when i was experimenting with the age of the beans.
so if it doesnt hit the 2oz weight i will tweak grind setting to maintain time? or same grind but pull longer, but if its 30sec max then it has to be grind setting?

The weight is just a starting point for tweaking your pull to get the taste you want. For ristretto, you want 1:1 ratio with grind weight, 2:1 for normal, and 3:1 or 4:1 for a long, all with different extraction times. If all you ever pull are 25 second normals, start with a goal of 2:1 and work up or down from there depending on the taste.

At the end of the day, it's all about the flavor.

19 grams of ground coffee should get you 38 grams of espresso in 25 seconds from first drop. That will read 32 seconds on the BDB timer since it counts the pre-infusion time before the first drop comes out.

bubbadude i did a test

15g at 30sec made 54grams slight bitter
18g at 32sec made 51grams bitter

how do i fix it?

15g should make 30g within 30sec right, 30g is like 1.05oz, this is suppose to be double shot like 2oz
im confused
