I feel like I should add that for anyone thinking, "This all sounds like far too much trouble," there are plenty of do it yourself hacks that cost little or nothing. For those interested in minimalist, hiking, cold brew, and other simple-feed techniques, you can use the top of a 2-liter bottle and a coffee filter. For those who are piqued to roast beans, there are youtube tutorials how to use an air popcorn popper to roast beans. Or to use a cast iron skillet to roast beans. I'm sure there are hundreds of these type ideas floating around the internet. I'm tempted with the air popcorn popper method. The only one I've personally tried is the 2-liter bottle/filter method for both cold brewing (you do it in the refrigerator) and backpacking purposes. It works well, and it costs (and weighs) nothing.
Also realize, for every do it yourself hack, there is an entire group of people who feel that hack is blasphemy. To each their own. Coffee has its zealots and cults. For certain.
