My burr grinder seized up yesterday at 6:45 AM, right when the beans were half ground. I grabbed the old blade grinder from the back of the cabinet and it turned my medium roast into dust in 4 seconds. Tasted like burnt dirt and I still drank the whole cup because I had to leave for work. Anyone else keep a junk backup that just makes things worse, or do you bite the bullet and buy a hand grinder?
Tbh a blade grinder doesn't really turn beans to dust in 4 seconds, it just chops unevenly so you get a mix of boulders and powder at the same time. That unevenness is why it tastes so bad, the fine bits over-extract and go bitter while the big chunks stay sour. A cheap hand grinder fixes that way better than any blade thing ever will.
