So, I got my new Gaggia Evolution, and very soon testing began. 1/2

believe is the right combination of coffee amount / grind thickness/
tamp pressure and i've reached ~2 ounces @ 24 sec using a double
basket.

The problem is in the way the coffee comes out: At the very beginning
it looks fine, but after very few seconds, the stream turns blond, and
in a way I can describe as wider but slower stream with waves.
The crema seems a bit pale also, and the taste also implies that
something isn't right, its a pretty dark roast and the coffee is way
too acidic and bitter.

The "Equipment": Gaggia Evolution
Nemox Lux grinder
~ 14 days old beans, the same mixture
I've used daily with my brikka

If the stream blondes within a few seconds, you have one or more of
the following:

Chanelling in the cake/puck - do the pucks stay in one piece when
knocked out? Are you tamping level? Not disturbing the pf as you
lock it in the group?

Too cool a machine - Are you thoroughly warming the machine up,
especially the grouphead and pf?

Grind is still too coarse.

That's all I can think of at present :)

Thanks Danny for the reply...

The machine was on for about 30 minutes, and still same results
(Blondes fast and sour taste). I've also tried different stages of the
deadband all with the same results.
The puck stays in one piece, but its moist inside.

I've also tried finer grinds (~1 oz. @ 40 secs...) with the exact same
stream.
