Manual dosing puts extraction timing in the operator's hands, so you can adjust pull length on the fly based on bean age, roast level, or customer preference. The self-tamping, high-density group head delivers a consistent puck compression, while Astra's thermocycling system paired with a 4.2 liter copper boiler keeps brew temperature locked in from the first shot to the last.\u003c\/p\u003e\n \n \u003ch3\u003eThermocycling Brew Temperature Control\u003c\/h3\u003e\n \u003cp\u003eAstra's thermocycling system circulates water through the high-density group head between extractions, preventing the temperature drift that plagues conventional machines during lulls in service. The 4.2 liter copper boiler transfers heat rapidly and recovers quickly after successive pulls. For a semi-automatic where the barista is making real-time decisions about extraction, stable temperature is the foundation that makes those decisions meaningful. You are adjusting grind and timing against a known constant rather than chasing a moving target.\u003c\/p\u003e\n \n \u003ch3\u003eAll-Stainless Construction with Brass Fittings\u003c\/h3\u003e\n \u003cp\u003eThe Gourmet series is built with a full stainless steel exterior and brass flare fittings at every water junction. Stainless holds its finish through daily wiping, steam exposure, and the occasional splash of espresso, unlike painted panels that can chip or discolor over time. Color panel options are available for branding. The GS-022 includes one steam wand for frothing and one hot water dispensing valve for americanos, with manual controls for both steam and hot water. Automated steam control is available as an option. Ships with one single and one double portafilter.\u003c\/p\u003e\n \n \u003cp\u003eA 2700W heating element powers the 4.2 liter boiler at 220V, and the quiet rotary-vane Procon pump connects to a plumbed water line (30 to 50 psi, filtered and softened) through a 1\/4-inch inlet with a 1\/2-inch drain hookup. Dedicated circuit required. A 5-foot power cord is included. Handcrafted in the USA from US-standard hardware.\u003c\/p\u003e","brand":"Astra Manufacturing","offers":[{"title":"Default Title","offer_id":51175778517277,"sku":"GS-022","price":3885.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/4716\/2909\/files\/40794_gs022_front_0c7b0521-09ad-4fd7-8cd2-6d9853179562.jpg?v=1776338460","url":"https:\/\/thechefstore.com\/products\/astra-gs-022-gourmet-semi-automatic-espresso-machine-one-group-head-all-stainless-220v","provider":"TheChefStore.Com","version":"1.0","type":"link"}
