I recently invested in a decent espresso machine for my kitchen and I'm trying to figure out which beans give the best results. I've tried a few local roasters but the shots either come out too bitter or too sour, so I'm wondering if it's a bean quality issue or my technique. Has anyone here had luck with specific bean origins or roast levels? I'd love to hear recommendations from fellow espresso enthusiasts before I waste more money on trial and error! 정보이용료 현금화 (https://reborn-ticket.com/)
