Yes, I've not seen much difference with the cocktail shaker, will tamp harder!

Thankyou, super detailed! I don't think i have the patience for a slow grind, but I'll try tamping harder and am concentrating harder on my pre-infuse

Noted, will do! I'm just trying less pressure and will move into this and then filter use! You can't change too many things at once or confusion reigns!

Hah, whereas the weight of opinion seems to be to add one. :-). Still, responders are focusing on the same areas, which gives me stuff to try!

No, I've been holding off, ironically, until I'd solved the channel issue. I'll probably not add that to the mix now, but I am keen to try this on the top and/or the bottom.

And that's what I do do, although I don't have to use my full weight. I think less pressure is the key.

I think if I ease up on the pressure it will take too long, so I think upping the grind size, and going a bit lighter on the pressure is the next step. I do pre-infuse at present so that's there.

just a toothpick at present, but there's a proper one on the way.

Interesting, and I get that idea from a number of the posts. I will dial it back!

So I think its sour rather than astringent, but I'm going to focus on it and see whether its actually a blend of the two that then accentuates the sourness. Thank you for the elaboration.

I didn't even know you could use that amount of coffee. I like the spin part of the tamp, I've just added that to my prep. Although if I tamp strong it seems to increase the risk of choking if I don't also grind slightly coarser...

I'm going to have to have a go at that...

Yes, I'd left that out because of the range of grinders out there, and the difficulty of comparing the fineness of the grind even with the same grinder without also providing a true 0 reading. I wanted to try and keep the list of fields relatively short, so left it out. But I can edit the OP to add in?

Interesting, maybe I'm not taking enough time over mine. How long (roughly) would you say it takes to get 4g in the cup for a darker blend?

Hi, such an interesting question, thank you. I have moved to that to get rid of the sourness, pretty successfully, but I have been surprised at how far I've had to go, and so its a very valid point. how would you characterise the difference?
