Report 3

Two brews with the Naked PF, Rocky now in the value of 9, were made with similar amounts of coffee and a 13 kg tamp. The brews were 50 ml in 25 seconds. You can here a comment after the first brew. Afterwards, there were some water on top of the cake and the surface was uneven. The second one was more dry and both had the best cremas so far.

In the first you can see some water coming from the base of the PF and the second one has steamed water coming to the PF as the top of the background plate shows steam.

I then tried to make some shots with the normal PF but there were still many problems. The coffee flowed unevenly to cups; 30 % and 70 % distribution and the quality was clearly worse. Maybe the 'horns' make the tamping more difficult and I need more experience.

I couldn't remove the filter from the Naked PF and asked even some advice from Sweden. People at Ristretto even told that there are PF's with fixed filters.

Well, using a lot force with I managed to remove the filter and noted by comparison that it was a triple filter. The regular PF started to work better as I tightened it more. My group head doesn't have the red spot, so it is slightly difficult to figure out the right place. Now the coffee flows to the cups evenly.

I also tried to brew fresh espresso, that was roasted only few days earlier (by Cafetoria, Lohja). We had ordered Gran Palomar espresso organico beans 250 grams. The first three shots were strong ristrettos (20-30 ml and 30 s), but the taste was best so far.
