Example Input: First time experience with Lavazza Tierra! I have been getting the espresso bean from a local roasting company. I don't have any problem, but my wife wants more aroma from my espresso shot. The reason I got the Lavazza Tierra! But, no success so far. I have the Bezzera bz07 machine with a Rockey grinder. I only got very light crema from Lavazza Tierra! also I don't smell any aroma. I tried pulling a shot with a bottomless portafilter, it looks very awful. I think the bean is old.
Example Output: Negative

Example Input: I think Namaste Gluten Free Spice Cake Mix is their best but vanilla cake is pretty good,too. I especially like it with whipped cream and strawberry sauce with a dash of ground orange peel. In my oven,the mix bakes better in muffin cups or a muffin pan than in a rectangular pan.
Example Output: Positive

Example Input: Been gluten free for 7 years now. Thought we were done with mixes that tasted awful. We threw it away because we did not like it. For my money, you can't beat Pamela's baking mix. But, the Betty Crocker chocolate chips are the BEST! So, don't give up Betty Crocker, just work on this one!
Example Output:
Negative
