{"product_id":"ace-defoamer","title":"Ace Defoamer","description":"\u003cp\u003eAce Defoamer is a 10% active, food-grade silicone antifoam for foam control anywhere in the brewery it becomes a problem — brewkettles, fermenters, yeast propagation, and blow-off buckets. It's FDA-authorized as a secondary direct food additive permitted in food for human consumption, and it's formulated specifically for filtered beers.\u003c\/p\u003e\n\u003cp\u003eIf you're converting from another chemical program, this is the direct replacement for Birko Antifoam 10, Birko All-Purpose Antifoam, and Five Star Defoamer 105 — same job, same chemistry class. A knocked-down kettle foam cap means bigger effective batch sizes, and controlled fermentation krausen means less blow-off loss.\u003c\/p\u003e\n\u003cp\u003eDosing is by the drop: add about one drop per five gallons during agitation, ideally before foaming starts rather than after. Subsequent additions are fine, but never exceed the FDA maximum of 200 ppm — roughly one drop per gallon. Available in 1-gallon jugs and a 4-gallon case of four jugs.\u003c\/p\u003e\n\u003cp\u003eWhite liquid emulsion, near-neutral pH, non-foaming by definition. It complies with 21 CFR 173.340 up to the 200 ppm limit. The SDS and technical data sheet are linked below. Non-hazardous: ships parcel or rides your pallet from Fort Worth or Atlanta — and we charge no hazmat fees, ever.\u003c\/p\u003e","brand":"TBI Pro Brew Supply","offers":[{"title":"1 Gallon Jug","offer_id":49202534449379,"sku":"4230","price":36.95,"currency_code":"USD","in_stock":true},{"title":"4 Gallon Case (4 × 1 Gallon)","offer_id":49453398819043,"sku":"414230","price":138.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1174\/6531\/files\/Defomer_1gal_0b410897-8027-497d-a12f-581b15057ebc.png?v=1785360705","url":"https:\/\/www.probrewsupply.com\/products\/ace-defoamer","provider":"TBI Pro Brew Supply","version":"1.0","type":"link"}
