Tried. Same result.

I'd avoid dosing too course to reduce sourness. Have you checked to ensure you are not getting any channelling? Try a bottomless PF to check for an even extraction. I've found a light nutation followed by a normal even tamp quite handy for reducing channelling.
Yes. I'm doing extractions with the naked PF. I'm not see signs of channelling, but maybe I'm confused. I tried WDT.
I'd say stick around the 25 sec extraction time. Extended extractions can often be pleasant but can also often taste salty to me.
Oh, thanks for point it. I also noticed the salty taste sometimes. I was searching the net for a comment about relation between long extractions and salty taste but I've never found anything. Good to know it.
Have you had your grinder and burrs cleaned/serviced recently, burrs nice and sharp? Is your hopper at least 2/3 full?
I tried with the Vario Home which is almost new and with the K30. Nope, I usually grind by dose...
You mentioned water temp, how are you measuring?
In the S1 you can select the temp.
Have you checked your water filtration (if you use any)?
Yes. La Spaz uses water filters.

I made it at 95C (like always), with a good amount of coffee for a nice thick pour. Worked fine as a naked single too. When we've consumed the subscription coffees this month, I'll be going back for some more.
I'm not sure if I prefer that you told me that the coffee for you was sour too or this.
Geez... The easy way will be to take a flight to London and try the coffee from first hand.
