{"product_id":"cool-brewing-fermentation-temperature-control-bag","title":"Cool Brewing Fermentation Temperature Control Bag - Insulated Cooler for Fermenters to 40L","description":"\u003cp\u003eThe Cool Brewing bag solves summer fermentation without a fridge, a chamber or a single watt of power: a heavy-duty insulated cooler bag that swallows fermenters up to 40 litres — bucket, carboy or small conical — and holds them at ale temperature on nothing but a couple of frozen bottles. Drop the fermenter in, add ice bottles beside it, zip it shut, and swap the bottles once a day; a heatwave brew day stops being a gamble.\u003c\/p\u003e\n\u003cp\u003eIt works the other way too: in a cold garage, the same insulation holds fermentation warmth in. The side zipper gives access for samples and gravity readings without unpacking, and after the batch the whole bag folds flat for storage. Internal 52×67cm — the Brewferm 30L bucket and most 30L fermenters fit with ice-bottle room to spare.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInsulated bag for fermenters up to 40L — no power needed\u003c\/li\u003e\n\u003cli\u003eIce-bottle cooling: swap daily, hold ale temperatures through summer\u003c\/li\u003e\n\u003cli\u003eAlso retains warmth in cold rooms\u003c\/li\u003e\n\u003cli\u003eSide zipper for samples without unpacking\u003c\/li\u003e\n\u003cli\u003eFolds flat between batches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eQuick facts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Cool Brewing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e fermentation temperature control bag\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e fermenters up to 40L (internal 52.1 × 67.3cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling:\u003c\/strong\u003e frozen bottles, replaced daily\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e summer fermentation, temperature stability, cold-room brewing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRelated products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/craftbrew.nl\/products\/rapt-fermentation-chamber\"\u003e\u003cstrong\u003eRAPT Fermentation Chamber\u003c\/strong\u003e\u003c\/a\u003e — the powered, automated alternative\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/craftbrew.nl\/products\/grainfather-gf30-fermenter-coat-insulation-jacket-for-gf30-conical-fermenter\"\u003e\u003cstrong\u003eGrainfather GF30 Fermenter Coat\u003c\/strong\u003e\u003c\/a\u003e — the fitted-jacket approach for conicals\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/craftbrew.nl\/products\/plastic-fermentation-vessel-30l-with-airlock-tap-transparent-food-grade-fermenting-bucket\"\u003e\u003cstrong\u003e30L Fermentation Vessel with Airlock \u0026amp; Tap\u003c\/strong\u003e\u003c\/a\u003e — the bucket this bag was practically made for\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/craftbrew.nl\/products\/rapt-pill-hydrometer-thermometer\"\u003e\u003cstrong\u003eRAPT Pill\u003c\/strong\u003e\u003c\/a\u003e — reads the temperature inside without opening the zip\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cool Brewing","offers":[{"title":"Default Title","offer_id":57545907798391,"sku":"000.015","price":49.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/6578\/9303\/files\/0001075_coolbrewingcoolerforfermenter.jpg?v=1791929137","url":"https:\/\/craftbrew.nl\/products\/cool-brewing-fermentation-temperature-control-bag","provider":"CraftBrew","version":"1.0","type":"link"}
