Have been brewing Solomon Grundy Kits for over 20 years, but putting on weight. I must add 4 Kg. sugar with these 30 bottle kits. I am thinking of changing to the kits where you do not need to add sugar. Will there be fewer Calories in these kits? There are 3870 Calories in 1 kg Sugar. I use 4 Kg = 15480 Cal. What I’m trying to say is….I get 30 bottles…..30 bottles of shop wine contains nearly 20000 cal…..nearly 5000 more!!!!
