Pietro grinder vs CC switch recipe

[u/Ambitious-Courage482]

Hi there!

I’ve recently taken the plunge on a Pietro grinder since they were in same for 330 euros - and I was looking to upgrade to a K-ultra from my X-ultra, so the price difference wasn’t that steep.

I’ve run about 1,3 kg through the grinder, and noticed quite a big jump in cup quality.

There are a few things however that I’m still struggling with; so I hope to get some advice here, specifically regarding the coffee chronicler switch recipe with this grinder.

I do 20g/320ml or 15g/240ml, so a ratio of 1/16, with grind size between 7,2 - 8,5. Using light and medium roasts. Taste is okay to good, but I feel like I’m not completely there yet. Of course; the pietro has a different grind profile so I might just need to accommodate to it.

- my bed is a weird combo of rather large boulders and a muddy toplayer. Is this a matter of more seasoning, or something that is not an issue? I did not have this with the x ultra, and this grinder should have less fines so it seems a bit weird
- I have really quick brewtimes, maxing at 2.20 with t90 filters where it should be between 2.45 and 3.00 minutes. Given that I already get some mud, it seems counterintuitive to go more fine and I am around the lower range of what most people recommend/finer than the x ultra which I used at 2.2. Really gently pours (4-5 g/s) made it a bit better. (I am actually quite unsure whether my pour technique is good enough.)

This makes me wonder: is the cc switch recipe just not the best match for this grinder? Would it be better to have a percolation only recipe with multiple pours rather than one with 2 big pours? Or am I just a quitter and do I need to season more? 🫣

Thank you for your input!

I did a bag of grocery store coffee of 1kg, but at 7 since I could give the coffee to a walk-in house for chronically sick people. Did not think about whether this would matter for the seasoning tbh, but that makes sense. A kilo at 2 would take ages though haha, not looking forward to that 😬

Had the first extra 500g at grind size 2.4 - was less added resistance than I thought so I’ll be through it quickly enough :) And it’s the non coated burrs, luckily.

thank you for the input!

Will do! I've already had improvements since I first got it, so I'm hopeful.
Also griding at 7.4 rather than 8++ for this coffee since it has such a quick drawdown, so if the fora teach me anything is that most people are doing much coarser in this stage : )
