Review of Butterscotch Cream Pie Flavor-WF:

This flavor is very good.  It's even pre-sweetened and no bitterness or alcohol flavor to steep out.  I mixed at 6% by weight so think about 5.5% by volume is a good amount.  Reminds me of pecan pie without the pecans on top.  If you need something good and fast and foolproof get you but until your other creations steep, this is it.
