Iâm relatively new to the espresso game and my espresso always tastes a bit sour⊠please help! Iâm using a Breville Barista Express. From what I understand, the sourness is generally because of under extraction. The water seems to be at around 190-200 degrees, so I donât think thatâs the issue. Iâve tried to dial in the grind size so that pulling a shot takes around 25-30 seconds. At that grind size, the pressure gauge is at the very top of the range. I believe if I go finer with the grind, then itâll take longer to brew and push the pressure up higher. Iâm not sure exactly what to do to address this. Could it be that Iâm tamping too hard? I push relatively firm, aiming for about 30 lbs of pressure. Thanks for the help!
Makes total sense! I donât think it has an (obvious) pre-infusion option, but Iâll do some research to find out.
Before I upgraded the electronics on my Gaggia Classic, I used to do a âpoor manâs preinfusionâ by leaving the steam valve open for the first few seconds of the shot, so that most of the water could escape that way instead.of thru the puck. Not sure if the same would work on your machine.
