Today, I came prepared, with my naked portafilter, a digital thermometer crippled from my Eric Svendson’s setup from home, and my Espro tamper.
While attention was focused on the latte art competition on the floor, I stole away to try my stint at the Rancilio Classe 6 unit at the door. A few points in summary:
My Rancilio naked portafilter locks in at 6 o clock
The Ditting-Mahlkoenig clumps to high heaven because of the lack of a doser to help in some unclumping. I had to use the digital thermometer to unclump the grounds in order to perfect my pour. I had spritzing in most my pours no thanks to the doserless grinder.
The Rancilio Classe 6 rapidly loses heat in the grouphead. I read initial temps of 205, and then it steadily decreases to a range between 165 and 175 degrees 20 seconds in. I’m sure past competitors would miss the PID’d temperature stability and machine build of previous SNBC sponsor who brought in La Marzocco. Even Nuova Simonelli had their WBC machines specially customized with a PID to ensure temperature stability.
The Spinelli roast worked very well with the Rancilios. I managed to test out one pour at the competition machine with the Boncafe roast, intended for the latte art comp, and it tasted inferior to the Spinelli roast. I would think Ross had tailored the roasts to suit his machines. Despite the temperature instability and the clumping, Spinelli pours from the Rancilio were all within a good degree of tolerance in body, flavour and acidity. Point in note, if all else fails in this year’s SNBC, be sure to use Spinelli roast. I’m sure it’ll taste quite fine to please the judges’ palates.
