Example Input: Love, love, love these crunchy little treats.  They remind me of "Munchos" but without the greasy tounge afterwards.  I don't usually like flavored snacks, but these are all great, not overwhelming and no gross aftertaste.  I subscribe to them so I will never run out:)
Example Output: 5

Example Input: I love this coffee. I do wish it came already ground as I don't have a grinder and use a blender instead. But it's worth it. Many flavored coffees I've tried only seem to have a flavored odor that doesn't reach the coffee, but this one manages both.
Example Output: 5

Example Input: This is the best thing from Gevalia.  I was drinking the Starbucks Africa and Verona before "the breakup."  I tried the Dark Breakfast from Gevalia, but it's horrible.  I can only drink it after adding the Maestro Lorenzo Espresso Intensivo.  That makes quite a nice cup with a good kick to it.  I even need a little cream in it to smooth it out a bit.  But this one is just right.  It's a nice strong cup that doesn't need cream, but can take cream without losing flavor.  This is the first hope I have had for saving my Tassimo machine.  I don't want to go back to the Keurig.  p.s.  I would still like a good decaf option.  Right now I use the Gevalia Signature decaf and add a shot of Gevalia decaf espresso to jazz it up.
