A burr grinder will give you noticeably better-tasting coffee, but there’s nothing wrong with a plain old blade grinder. If you are currently grinding coffee for a drip machine, French press, or pour-over machine, a blade sander will work in most cases. My personal favorite is this KitchenAid I found it on Amazon a few years ago. It is sturdy and has a small removable bowl so you don’t have to turn the whole grinder over the coffee machine to empty the plot. But most importantly, it gets the job done. Add fresh, locally roasted beans and you’re good to go killer cup of coffee. If you pulse it instead of holding it down for one long grind, you’ll get a more consistent grind and won’t end up with as much almost whole beans floating at the top of your coffee filter. A more consistent grind = more flavor in your cup.
