We dig into why brewing at home delivers better quality, value, and ease, then zoom out to Big Coffee’s shifts—Starbucks’ wobble, Luckin’s app-first push—and finish with a clear guide to experimental processing that unlocks bold flavor. Along the way, we share practical gear we love and how to build iced “espresso” drinks without an espresso machine.

• quality and convenience gains from home brewing
• cold brew concentrate as an espresso stand-in for iced drinks
• simple syrups, filtered water, and easy gear wins
• Ethos Kalita-style brewer and leak-proof travel mug
• Starbucks as simulacra and the market wobble
• Luckin’s gamified coupons and race-to-the-bottom risks
• competing at the top with objective cup quality
• value through traceability, direct trade, and fair pay
• experimental processing: anaerobic, selected yeasts, co-ferments
• flavor-forward lots from Pepe Hijon and Diego Bermudez
