This is bizarre and I have to ask about it where folks would know best. I've recently started roasting my coffee at home. I had the Zach & Dani's and that thing kicked the bucket after less than 4lbs of coffee. So I switched to a stove top popcorn popper. I recently finished my 10lb sack of Indonesian Sumatra and picked up a 10lb sack of Indonesian Java. I used a slightly lighter roast than i did before. Don't ask what roast level it is, I'm not smart enough to know that yet. I brought some to work and it made a mess out of the coffee maker. It's like the water didn't flow through fast enough. I figured I ground it too much, or used two filters by mistake. This morning I made two pots at home in my home drip maker and the same thing happened to both pots. Something is up, and it's related to the bean or the roast. I find this really bizarre, but does anyone have any thoughts?
