>>212987299The base dough recipe for a typical scone contains 50+ grams of granulated sugar, while biscuits have none.
Scones are often made with fruit mixed into the dough, while biscuits never do.
Scones are often finished with icing or coarse sugar on top, which again would never be done with a biscuit.
Whether you want to consider scones "sweet" or not is a fruitless argument, but it is factually true that scones are significantly sweetER than biscuits on account of all the sugar and fruit that are added to them. Biscuits are a savory quickbread made with only flour, butter, and milk; no sugar or sweet things mixed in. We even pair them with savory toppings like butter, cheese, and gravy.
