The original Kilner jar, first invented by John Kilner and Co. in the 1840’s, is a product which has stood the test of time. For over 150 years the clever iconic design with its air tight seal has been helping households all over the country to store preserves, pickle, jams, and relishes and keep them fresh. They are also popularly used for storing dry goods such as flour, sugar, tea, or coffee. We recommend the larger three litre jar as the perfect vessel for the making of sloe gin.
