Each pack contains three 10 ml vials, totaling 30 ml, which are ready to use. The solution is sterilized and acidified to a pH of 4.0 to ensure maximum solubility and uptake of zinc by the yeast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan style=\"font-size: 0.85rem; font-family: helvetica;\"\u003eImproved Yeast Health:\u003c\/span\u003e\u003cspan style=\"font-size: 0.85rem; font-family: helvetica;\"\u003e Zinc is essential for yeast protein synthesis and growth, resulting in increased viability and overall health.

When the yeast dies, the zinc is released and effectively taken up by the yeast added to the wort. An advantage of Servomyces is that it can be added at the end of the boil, as the yeast cells protect the zinc from binding to proteins in the hot break trub.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eZinc concentration in Servomyces: 50,000 ppm zinc\u003c\/li\u003e\n\u003cli\u003eDosage: 1 g\/HL, which provides a total zinc concentration of 0.5 ppm in the wort\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhy use Zinc Buddy instead of Servomyces?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWLN4700 Zinc Buddy is a sterile and pre-mixed zinc solution that can be added directly to the cold side. Unlike Servomyces, which must be dissolved and added during the boil or in the whirlpool, Zinc Buddy is immediately available and easy to use.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eZinc Buddy provides an additional dose of 0.2 ppm zinc, for a total zinc concentration of 0.3 ppm in the wort.\u003c\/li\u003e\n\u003cli\u003eCan be added after cooling, allowing for precise dosing without nutrient loss.\u003c\/li\u003e\n\u003cli\u003eSimplifies zinc addition for brewers seeking an alternative to Servomyces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAlthough Servomyces allows for a higher total zinc concentration (0.5 ppm vs. 0.2 ppm from mineral zinc), too high concentrations of mineral-based zinc can lead to undesirable off-flavors in the beer. Zinc Buddy thus provides a balanced approach, and is particularly useful for brewers who do not already use Servomyces.\u003c\/p\u003e\n\u003cp\u003eIn summary: If you already use Servomyces, this yields the best results due to the higher bioavailability of zinc. But if you want a simple, sterile, and user-friendly alternative, Zinc Buddy is a good choice for optimal yeast health and efficient fermentation.\u003c\/p\u003e\n\u003cp\u003eClick here for information about \u003ca href=\"\/en\/products\/wln3200-white-labs-servomyces-gjaernaering\"\u003eWLN3200 Servomyces\u003c\/a\u003e.\u003c\/p\u003e","brand":"White Labs","offers":[{"title":"Default Title","offer_id":41902140948578,"sku":"WLN4700","price":139.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/8422\/6914\/files\/26ca40eb25a6635c249bd8baee2cd02b-image.jpg?v=1746188883","url":"https:\/\/brewshop.se\/en\/products\/wln4700-zinc-buddy-gjaernaering-3-x-10ml-white-labs","provider":"Brewshop","version":"1.0","type":"link"}
