Is Grinding Coffee at Home Worth It (And What Type of Grinder Should I Get)?

This video talks about coffee beans, what happens to them when they are ground, the benefits of using freshly ground coffee, and the different types of grinders available for home use. This also includes some lab (err, kitchen) research I did on this topic.

The grinders used for testing in this video were:

Capresso Infinity Conical Burr Grinder

The coffees used for testing in this video were from Counter Culture Coffee in Durham, NC. They blends used were:

Apollo - https://counterculturecoffee.com/shop...
Big Trouble - https://counterculturecoffee.com/shop...
NOTE: While these blends are availible year round, the specific coffees used in the blends vary thorough the year, as coffee is a seasonal product. However, Counter Culture typically is very good at keeping their year-round product consistent throughout the year.
