Struggling to get slower pulls
Hi all! I just picked up a Gaggia Classic. I’ve had it for a couple days now and have been tinkering with grind size and bean weight to get a slower pull.
I’ve gone up to 20g and a very fine grind size (about a 3 on my Baratza). It’s only takes me about 18-19 seconds to pull a 2oz shot. Any tips on how to slow that down more? Do I need to get a different filter?
I also am struggling with the temp control on a second shot. The first is always great in that regard but when I pull a second to make my wife’s it comes out almost boiling and a bit bitter like it’s burned. I’ve tried the trick to flush water through the boiler to cool it down but the light doesn’t turn off so I just go for the next one because I don’t want the tray to overflow.
Any tips for this beginner?
Thanks!
