Milkshake IPAs have a ton or room to play with depending on your preferences. You can swap out the hops, the fruit puree, the vanilla addition, and more! When making alterations be sure to keep your end goal in mind - juicy and sweet. Certain hops will play better, as will certain fruits. If it's too sweet remove the vanilla and add half the lactose!
Milkshake IPAs have a lot of flavors going on at once and would pair well with a sharp cheese to develop contrast between the flavors. Mild cheese may be overwhelemed by the immense flavor of this brew.
