My dh won't drink organic milk, he says it tastes weird. I love it and so do my girls. I do notice that it's richer than regular milk. It was explained to me that organic milk is produced by cow who make the milk when their body decides to make the milk, there for it's richer. Regular mass produced milk is from cows that are given hormones and other "stuff" to make them produce milk faster and therefor the milk is watery. I drink 1% organic milk and I swear it tastes even richer then the 2% I was buying at the grochery store. I bought the girls organic chocolate milk that is made with full fat milk and I swear it's so rich it tastes like cream. I love it though. Also, organic milk is full of omega rich fats from the cows grazing on grass and hay and the fat is very different then the other milk from corn fed cows.
My point is that maybe he's not used to the richness of the milk and the abundance of good fats. Try mixing the organic half and half with the other kind of milk for awhile and slowly wean him onto organic. I would not go back to the other kind though because it really is not good for you because of the diet the cows are on. Do a google and try to find some info on the fats in organic as opposed to non-organic milk, to show your dh. It will really surprise you. I was always afraid of milk fat and stuck to skim and fat free milk products. Not now, I eat full fat yogurt and 1% milk. Since changing our milk source, meat source (organic grass grazing) and oil source (coconut oil for everything calling for oil) 4 weeks ago I have lost 6lbs. I did not change anything else. I eat the same amount and more, the same type of dishes.
