High capacity frothing is finally here. We've combined the volume of our FourSide jar with an innovative, stainless steel frothing blade. The result is a quick, effective way to froth or aerate liquids. 2 quarts of total volume provides a huge capacity for producing frothed liquids and foam. Instead of repeatedly creating single servings, you can now produce in batches and serve several customers at once. Our stainless steel blade features a “wave” bend which enhances the frothing capability—easily doubling the volume of many liquids. The blade works great for cold foam, whipping cream, hot chocolate, syrup and more!
