Example Input: Brew style: french press, espresso Smell: Nothing special here, decent 'coffee' smell with some earthiness.  No caramel notes, no sweetness. Taste: Mild, earthy, somewhat smokey, dirty mouth feel, finish is short.  I mostly brew with a french press but i tried it in my espresso maker just to see how it would fair.  The caffeine seemed very pronounced to me, there was no sweetness to speak of.  It did have a very nice crema though. Overall: I wont be buying this again, its nothing special.
Example Output: 3

Example Input: This is the pancake mix we go to when we don't have buttermilk in the fridge (don't think the vinegar trick is worth it so we always do fresh) to make Alton Brown's buttermilk pancake recipe.  This Stonewall mix is a good option and the flavor is the best of any store bought mix by far! It might cost more, but it really is superior to the other prepared mixes.
Example Output: 4

Example Input: these are grossly overpriced.  It is a package of three boxes but when you take into account that they are a dollar of two per box than they should be, you then have to pay for shipping.  Sorry, I would skip them.  My local grocery store carries them and a box is anywhere from 2.98 to 3.49 each.  Although these are healthier than some other cookies, you still have to watch the fat, sugar and salt contents.  Whole foods are much better for you but in a moment or two of indulging, these fit the bill.  Just the price on this site is ridiculous!  Ask your grocer to start carrying them.
