Calories in Starbucks Java Chip Frappuccino with lactose-free milk run from 275 in a Tall to 448 in a Venti, a bit lighter than whole milk since this carton carries less fat per ounce.
A Grande comes to 378 calories with 17.9g of fat, down from 19.8g in the whole milk version. Sugar stays close between the two, since the mocha sauce and chips supply most of it.
