Great to read that you have eliminated the grinder as a cause and are homing in on a solution, Tom.

Hi Mike,

thanks! I've made a video of a double extraction, it's on my flickr, I will link to it when I get home today. It's not great, but... read below.

One thing I thought about regarding the grinder, after reading this bit in the Nino thread in the grinders section (by Eric):

I have the small Mahlkoenig hopper fitted to my Nino and usually tip in about 250 grams of beans at a time, this normally lasts me a week.

I pulled a shot yesterday, three days into the last top up, and that only ran for 15 seconds !!!!!!!!!!!

After reading about the need for some downward pressure on the beans being fed into the burrs I looked into the hopper to check the level of beans. They were low, but not that low.

I opened up another 250 gram bag from the same roast and poured this into the hopper, changed nothing else, and the next shot ran for 27 seconds. To me this proves the need for either a fair ammount of beans in the hopper or some other device to exert a downwards pressure on those that are in there and about to meet the burrs.

Hmm I'm curious if that's the problem on my grinder. I know that James was using it with the hopper around 80-90% full of beans and I normally use it with around 120-150g of beans in there. Curious how much that affects the grind settings. Perhaps it's the reason I was grinding so fine and why it was all going side ways? Now the hopper is around 50% full and I've noticed a change in the way the shots flow, then again it might just be me playing with the grinder settings.

Hi everyone,

well I've had it, the machine is off for good now and I probably won't turn it on for a while. I'm both p*ssed off and dissappointed, perhaps it is my technique, perhaps it's the machine, dunno and to be honest I don't really give a sh*t.

I'll use my Chemex for now...

Regards,
