quick, easy tamp that seldom has spritzers
Posted: Mon Mar 08, 2010 10:20 am
OK - took me a while, and some input from members here to get where I consistently have little or no spritzers.
I've got a small scale that sits under the doser of the major, and the coffee goes right into a cut down yogurt cup that weighs four grams, so I always subtract four grams from the total weight, and know the weight of each shot. The dosered Major does a great job, I have never had a clumping issue.
I go from the yogurt cup to the portafilter, thwacking the portafilter four or five times, helps settle and distribute.
I do a really quick series of circular rotating motions that overlap thru the top of the grounds with a needle - mainly to ensure that the grounds distribute evenly with no gaps around the edges of the portafilter. I don't really go very far down into the basket probably not even halfway down.
Finishing in the center of the portafilter, this leaves a slight amount less coffee in the center of the portafilter
I'm trying to guess at it being the same amount less in the center that the convex tamper is. Then I do a firm nutating tamp, leveling the edges with my fingers on the edge of the portafilter as I finish. I'm using a Bumper convex tamper that Mary at Chris Coffee suggested. Someone here (mgwolf?) suggested that the S1 did a lot better with a nutating tamp - I think that was when I started to pull better shots
Hell of a lot harder to write up than it is to do.
This is a quick easy consistent way for me to get a shot with no spritzers consistently on the s1
The Vivaldi has a nut hanging down from the screens, that holds the screens to the group head. I'm thinking the method I use allows for the nut.
