No, what I meant was: if you wanted to get an idea what the fully aged Brick tasted like, (without having to buy a 2.5lb/5lb loaf) maybe you could buy a couple slices of the Bier Kase from a deli or cheese shop near you if you can't find the fully aged Brick. Some say it's similar in taste. You could even try on a slice of pizza.
I just ate the last 3 slices of the Brick half with more cheese, reheated in the convection toaster oven. I didn't grate it, I used a wire/roller type cheese cutter & cut some very thin slices and it melted well and had more snap instead of the long stretch mozz has. It did still stretch a bit though. I don't know if this is any help with your Mack's clone without trying some mild & aged Brick yourself!
