No automation, just you, the ritual,  and the coffee. It's the only spring-lever machine Clive stocks, and that's no accident.

You get incredible flexibility (brew-only mornings, milk drinks on weekends), fine-tuned temperature control for different bean origins and roast levels. You don't have to compromise experimentation or fun with its intuitive side-paddle and pump-level flow-control system.  This is the machine for someone who's serious about espresso but doesn't need a rotary-pump plumbed dual-boiler.\u003c\/p\u003e","brand":"Lelit","offers":[{"title":"Black","offer_id":44308250263640,"sku":"SI6656BK","price":1999.95,"currency_code":"USD","in_stock":true},{"title":"Stainless Steel","offer_id":44308250296408,"sku":"SI6656SS","price":1999.95,"currency_code":"USD","in_stock":true},{"title":"White","offer_id":44308250329176,"sku":"SI6656WH","price":1999.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2425\/8607\/files\/MaraX3_BLK_Front.jpg?v=1783013430"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2425\/8607\/collections\/Espresso-Shot-Pulling-and-Steaming.jpg?v=1779211821","url":"https:\/\/clivecoffee.mom\/collections\/heat-exchanger.oembed","provider":"Clive Coffee","version":"1.0","type":"link"}
