Yogurt with active cultures can significantly increase your gut health, but most store-bought yogurts do not contain those active cultures. Make your own active culture yogurt at home in just a few easy steps with the 7Penn Yogurt Maker Machine. Yogurt is made through a fermentation process where cultures are incubated for an extended period to transform milk into the most delicious yogurt you have ever tasted. Our easy-to-use digital screen allows you to set the ideal temperature for your cultures and set a 8-12 hour fermentation time that will auto shut off when completed. For creamier yogurt, use a higher fat content dairy or plant-based milk. Utilize our yogurt machine for other fermented foods including kefir, flan, natto, and more.
