I have not tried a lot of different milk alternatives, but I have found one that I really enjoy- Almond Breeze.
It is a product of the Blue Diamond company. I had tried some almond milk that was the Silk brand, but I did not like the texture.
This almond milk is free of soy, lactose, gluten, dairy, and many other things. I went for almonds instead of soy because of the amount of estrogen/ hormones that are in soy.
I have tried the original in the Silk brand. It was ok, but the almond taste/smell was strong to me. I drink the vanilla! I tell people that tastes like I am drinking a vanilla milkshake (only a thinner consistency).
