I notice that one list member said his gaggia had a temp of 170F at the =
head and hinted that was too cold, I read where 85C approx 170F was the =
right temp. What is the general opinion?.My gaggia is 90C.

Hi Ray,
There's some differences in opinion. The Italian 
Coffee Taster's Institute certifies stores when 
they keep the temperature between 85C - 90C (185F 
- 194F). Various US mavens, including the SCAA, 
recommend 90C - 95C (194F - 203F). Illy like his 
coffee at 95C precisely. Finally, Schomer likes 
his blend up at 205F (96C).
Some of it has to do with the degree of roast. 
Lighter roasts like hotter water to keep acidity 
in check, darker roasts like cooler water to keep 
bitterness in check. Also, for me and my fairly 
fast Freshroast, 90C to 95C works better, whereas 
a really slow drum roaster coffee may do better in 
the lower range.
But in any case, your 90C is excellent, especially 
for the most common Vienna roast level espressos, 
whereas 170F, or 77C, is completely hopeless for 
any roast, even Starbies. The thermostat needs to 
be changed, and the steam switch could be surfed 
in the mean time.
