Vaseline oil for oenological use. 1 liter bottle. Also known as petrolatum, vaseline oil is a product with neutral characteristics, therefore ideal for processing in the food industry: it has a semi-transparent color, is odorless, tasteless and insoluble in water. Polsinelli Enologia proposes vaseline oil in a 1 liter package, perfect for use with stainless steel tanks with float. Vaseline oil should be poured between the edge of the float and the wall of the tank, in order to perfectly isolate any food liquid from the action of the air, preserving its organoleptic characteristics. If necessary, it is possible to use 1 liter Vaseline oil to obtain a surface separated from the liquid that acts as an insulator even without the floating cover.
