We lose power sometimes, through thunderstorms, ice storms, and routine maintenance by the electrical company. Sometimes, the loss of power can last more than a few hours--during one ice storm, we lost power for about two days (we had to go to my in-laws' place for that one, since we lacked heating backups).
Well, when we have no power, I have no coffee. I keep whole bean coffee around. Ground? Not so much.
A few days ago, I ordered a manual coffee grinder. It arrived yesterday, and I just used it to make a cup of coffee. The drawer that holds the ground coffee is only big enough to make one cup, but since I'm the only coffee drinker in the house as of yet, that doesn't matter.
It works. It works really well. Apparently, it's adjustable, and mine came adjusted for a very fine grind--it's only slightly coarser than an espresso grind--exactly the way I like it. It takes about four minutes and plenty of elbow grease and stamina to grind enough to make a full cup of coffee.
There's a very slight difference in flavor, but I'm not sure what causes that, and it's not enough for most to notice. I do think it's an improvement, though, so...yet another plus.
It's also quite pretty, so it serves a dual purpose.
Definitely a good purchase, and a good addition to short-term power loss emergency preps. Especially when combined with this, which is what I used to make my single cup of coffee with the new grinder.
