Designed exclusively for the G40 and fully integrated with the Grainfather Connect app, this controller transforms what could be a complex, hands-on process into a streamlined, repeatable brewing experience without sacrificing the control that serious brewers demand.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhat sets the G40 Controller apart from basic temperature controllers and third-party alternatives is its deep, native integration with the Grainfather ecosystem. Programme full multi-step mash profiles, set precise boil power levels, schedule timers, and monitor your brew remotely — all from the controller interface or directly through the Grainfather Connect app over Bluetooth. The controller manages heating element power, pump operation, and temperature targeting in a single unit, eliminating the need for separate timers, manual pump switching, or temperature probes cobbled together from different systems. Every parameter of your brew day is visible, adjustable, and logged in one place.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhether you're following a complex decoction-inspired step mash, holding a precise protein rest, or simply dialling in a single-infusion brew with consistent results every time, the G40 Controller gives you the precision and confidence to brew to recipe — not to approximation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e⸻\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eKey Features\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFull Grainfather Connect app integration — Bluetooth control and monitoring\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eProgrammable multi-step mash profiles — temperature, time, and rest control\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAdjustable boil power settings for controlled, consistent boils\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eIntegrated pump control — no separate switching required\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eReal-time temperature monitoring and adjustment\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePurpose-built for the Grainfather G40 — plug-and-play installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e⸻\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eUsage\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBest suited for: Single-infusion mashing, multi-step mash profiles, step mashing, decoction-inspired brewing, precise boil control, automated brew day management\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCompatible with: Grainfather G40 all-in-one brewing system, Grainfather Connect app (iOS \u0026amp; Android)\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e⸻\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eQuick facts\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]\"\u003eBrand: Grainfather Compatible system: Grainfather G40 Connectivity: Bluetooth — Grainfather Connect app Control: Temperature, pump, boil power, mash timers Platform: iOS \u0026amp; Android Use: Mash control, boil management, full brew day automation\u003c\/p\u003e","brand":"CraftBrew","offers":[{"title":"Default Title","offer_id":57098142318967,"sku":"CB00036","price":159.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/6578\/9303\/files\/Grainfather_20G40_20Controller-1.webp?v=1778963665","url":"https:\/\/craftbrew.nl\/products\/grainfather-g40-controller-advanced-brewing-controller-for-g40-all-in-one-system","provider":"CraftBrew","version":"1.0","type":"link"}
