Hi Tina, no what you've heard about any wood pulp in our Triple Thick Milkshakes is not true. Our milkshakes are thick because of our blending process and the ice milk formulation we use. Our machines cool the dairy mix to the proper temperature blend it at the correct speed and mix it with flavoured syrup. Much the same way that using ice cream versus milk at home in the blender would make a thicker milkshake the solids and fat content of our ice milk and other ingredients help ensure a thick smooth shake. All of the ingredients can be found right in our Nutrition Centre so feel free to take a look. Hopefully that clears things up a bit.
