Evening, I've been practicing with some Co-op beans and trying to get a good ratio/pull time on my DTP. Good beans are arriving tomorrow but thought I'd get used to the whole process with these ones first. Grinding 17g into the pf straight from the SGP. I don't have a funnel and therefore clump management isn't the best. A funnel is on order. I'm aiming for roughly 1:2.5 in terms of weight in/out. Shot 1 - Grind setting of 8. Absolutely nothing out of the machine and it shut off after a minute. Water on top of puck. Shot 2 - Grind setting of 9. A total of 4g into my cup. Water on top of the puck again. I went to bed a thought about reading the manual. I didn't read the manual. Morning came and I read on here that someone suggested a grind setting of 15. I gave this a go: Shot 3 - Grind setting 15. A little better but the flow was still drippy. I probably got around 30g in the cup. Tasted awful and bitter. Really gloopy puck. I thought 15 was quite a course setting so decided to change a different variable - my tamp. Shot 4 - Grind setting 15. Lighter tamp yet still quite firm. Stopped the machine at 48g. Not as bitter as shot 3 but still not great. Shot 5 - Tried to replicate shot 4. Not sure what I changed but it was rounder in taste. Perhaps a slightly lighter tamp. Still too smoky to my tastes though. Puck was still kinda gloopy. I can see two things hindering my quest for coffee greatness here: 1) Co-op beans and C) clumps perhaps leading to channeling. Though saying that wouldn't this lead to water running through too quick and therefore sour tasting coffee? I'm a little surprised that the lower grind settings don't give any results at all, especially as I've read that SGP owners have struggled with not being able to grind fine enough on this grinder. Any pointers greatly appreciated, even if that includes "wait for your new beans to arrive". Cheers David
