Here is a triple. I upped my pressure to 10-bar and the espresso is great. This shot ran forever and was a thick sweet milk chocolate. The blend is a 14-day old Classic Italian Espresso Blend from Sweet Maria's. I let them roast it this time.
Here's one from this morning. This was with 15g of Ambrosia, about 8 days after roast. I preheated the water in my Carezza to about 155, which gets the extraction temp in the 200 range fairly consistently. Preheating the water has really opened up the extraction space with this setup. I've been playing around with dose and grind, but when I can get good flavors they seem to be either muddy and indistinct, or overly concentrated, it's been tough to find a good middle ground. I'm not sure if this is a limit of my set up (lelit grinder) or more due to my technique.
Here's the pour, which looked about average pour wise, and a little short volume wise, with 1oz (15g) in about 22 secs. Any advice/observations/critiques are welcome.
