In Canada can you buy untreated apple cider?
In the US it is pasteurized and an additive is put in it to retard spoilage.
When we were kids my Father used to buy a barrel of it that contained 1/3 pear juice. Then he added honey, oatmeal, raisins and whiskey. We got the top of the barrel as sweet cider, he got the middle as hard cider and my Grandmother got the bottom of the barrel as vinegar.
