What are the advantages of a manual grinder over an electric grinder?

[kopikopi]

I was wondering if anyone could provide me with the advantages of using a manual (hand crank) grinder over an electric grinder?

I have always heard that manual grinders have an advantage over electric grinders because manuals avoid rapidly heating up the beans, which preserves a lot of flavor (but I'm not certain if this is accurate). Is the difference in flavor noticeable?

Thanks!

I heard the same thing, but I couldn't tell any difference.

I have a hand grinder because:
1. It's cheap.
2. It works for my coffee making process (small amounts for just me).
3. It's easily portable since it needs no electricity and it's light. So I can take my coffee making stuff on vacation with me.

Cheaper (usually) and not near as noisy compared to an electric grinder - other than that, not too much.

Biggest factor for me is the lack of grounds retention. What goes in my hand mill comes out, nothing left behind.

The coffee beans will make the most of all

Sounds like the hand grinder has the advantage.

Yeah kinda does. I've used one in the past. Didn't care for it really, it was nice and all but wasn't my style. Honestly I didn't want people looking at me wondering why my right arm was more buff then my left!

I have both kinds at home, and they're both burr grinders. Sometimes I'm not in the mood to use and clean the electric grinder, so I use the manual one instead. I can see your point about how the manual one doesn't heat up the beans as it's grinding, because I take my time turning the crank and I rest my arm (mainly my wrist) once in a while. I can also tweek the "grind" of the manual one easier than the electric one. A manual grinder is great for small grinding chores. But if you're going to need to grind a lot of beans, you'd probably want an electric grinder.

Good points PR... some hand mills can grind quite agressive/fast to make short work of the task at hand, but this depends on burr design. My KyM mill is perfect for espresso having stepless adjustment and an aggressive burr feed, being able to chew through 15 grams in about 90 turns. I have read of some mills requiring as many as 400 turns for 14-15 grams and that WOULD get old quickly. Having a hand mill also makes switching back/forth between coffees quickly because nothing is retained to foul the next offering.

Electric mills certainly have their place, but for espresso a good hand mill costing $50-100 can easily be on par with electric mills costing as much as $600. I have no experience using a hand mill for coarser brew methods such as drip, press, etc. so nothing to suggest there.

Realistically there isn't ONE electric or hand mill that can cover all the bases and do all of them well. That's why most people have more than 1 grinder in their arsenal.
