High Voltage – kveik similar to Lutra kveik High Voltage from WHC Lab is a thermotolerant dry yeast that ferments cleanly at 31–35 °C. It produces few esters, so hops and malt come through clearly, and it can be used for almost any beer style, including pseudo-lager. The yeast is especially well suited to homebrewers with limited cooling options, as it thrives at much higher temperatures than traditional strains. High temperature means fast fermentation. For breweries, that means shorter tank time and less need for cooling, and therefore lower energy use. At home, it means you can make a clean beer without a fridge, as long as you can keep it warm. Suitable for Amber Ale, Bock, Brown Ale, Double IPA, German Lager, Helles, Imperial Stout, IPA, Kölsch, Lager, NEIPA, Pale Ale, Pilsner, Porter, Red Ale, Stout and West Coast IPA. Technical data yeast: Saccharomyces cerevisiae pitch rate: 3–10 g per 10 litres (30–100 g per hL) recommended fermentation temperature: 31–35 °C fermentation time: 2–3 days attenuation: 76–80% flocculation: high alcohol tolerance: 17% How to use High Voltage One 11 g pack is enough for 20–25 litres of wort. For beers above about 6.5%, use two packs. The yeast does not need rehydrating and can be sprinkled directly onto the wort at fermentation temperature, around 33 °C. Below 25 °C, fermentation becomes slow and fruity. Keep the temperature up with a heat mat, ideally with a temperature controller. Check attenuation with a hydrometer before packaging, even though fermentation is often finished in two to three days. Read more about High Voltage Technical data sheet Frequently asked questions about High Voltage What temperature should High Voltage ferment at? The recommended range is 31–35 °C. Below 25 °C, fermentation becomes slow and fruity. How much yeast do I need for 20–25 litres? One 11 g pack. For beers above about 6.5%, use two packs. Do I need to rehydrate High Voltage? No. Sprinkle the yeast directly onto the wort once it is at fermentation temperature, around 33 °C. Can I brew a pilsner with High Voltage? You can brew a clean pseudo-lager: a beer that tastes like a lager but is fermented warm and fast. A traditional lager with lager yeast needs cooling and more time. Do I need a diacetyl rest? No, High Voltage does not need a diacetyl rest.
