This is not a conversation about guns. This is a conversation about items that have withstood abuse that are near unbreakable.
Some items I have heard referenced as AK47 of:
Gerber MP600: It’s a multi tool
Old Thinkpad Laptops
Mag lights
Toyota Hilux
I switched to a French Press recently-ish. Instead of 4 or 5 cups of weaker coffee from my single serve drip thingie, I have 2 strong cups from my French Press and am ready to go. I’m thinking about trying a pourover to see how that is. Espresso is tasty and strong, but I don’t think I’d want it NEARLY enough to justify a machine. I usually only do espresso when I’m traveling, makes me feel fancy having a latte in the big city haha.
All that said, coffee is very individual. There is no “right” answer. If you’re happy with drip, than drip is the way. :)
If you want pseudo espresso grab a moka pot. You can snag them for like $20-50 and they make a good strong espresso style brew on your stove.
