if you don't want the sourness of the yogurt, try putting inulin in next time (you should be able to buy it at places like Whole Foods). It's a pre-biotic, so it's beneficial in yogurt, it's literally like sugar so it'll cut down on the "sourness".

Hipmama, how do you make yogurt with hemp/almond/soy milk? I tried once with soy and it just curdled. I know it needs something in it, I believe a type of sugar. Do you use a particular brand?
