I saw a James Hoffman vid the other day, can’t remember which one, I’ve watched a few! But he said that it didn’t matter how much beyond you tamp past the pressure required to compact the grinds together. My impression was that once that point is reached it’s difficult to go further, no matter how hard you press. I’m pressing hard and seem to get the timing pretty consistent and the coffee is tasting alright I think. I quite like a bit of acidity!
Yes currently obsessed with this. I’m getting there, I think. I need to get a slimmer drip tray to be able to see the flow now I’ve got a bottomless portafilter. On and on the spending goes. My fucking scales are on the blink too!
Just got a VST precision basket. Early results are promising.
My old ones were turning off mid-brew and once I got an espresso machine they also proved far too laggy to be accurate when trying to stop a shot. I was looking at the Acaia Luna, espresso specific jobbies but at something like 300 quid (!) they are really well out of reach. These aren’t cheap at £80-ish but do everything the others do. They can be used for pour-over too (they will measure flow rate if you want them to) and have a mode for that and espresso.
So far I’m very impressed. They are metal, so feel nice and solid. They fit with a cup under the naked portafilter much better than my other ones and without having to remove the drip tray. In espresso mode, they sense when a cup is placed on top of them and then start weighing and timing once the first drip of coffee hits the cup. They really work! I’ve dialled in a new coffee this morning (Red Brick) much quicker than was possible before because they are that much more accurate.
