I was so excited when I heard about this product. I love pork rinds. But these have a nasty chemical smell and they really don't taste good at all. Don't waste your money. I actually threw the remaining 17 packages away. They REALLY SUCK!!!!

Ex Output:
Negative

I got the licorice at a cheese shop in New York and by the time I got home it was all gone. So got on the computer and found and bought some. That's how much I liked it. I have not done the before and do not regret buying it. Yummmmmm.

Ex Output:
Positive

Puroast Low Acid Coffee If all you want is low acid, try other beverages. With Data. To start with I do experience occasional heartburn, reflux, etc, so this was a very exciting taste test. I brewed a pot of fairly well renowned regular coffee, and a pot of Puroast. I poured both into identical cups, no milk or sugar to start with. The regular coffee had a deep brown color, while the Puroast had a black brown color. I tested the pH of both, the regular was about 5-5.5 while the Puroast was indeed 7.0 or neutral as claimed. First taste was of the Puroast as I did not want to be prejudiced by the regular taste. Good grief... It was wet, it was warm, very flat taste with no finish, hardly what I would call even an average cup of coffee. The best comparison is that to a day old coffee that has been left to evaporate and oxidize. Perhaps burned charcoal aroma with hints of bitter chocolate and caramel? The standard coffee by comparison had a rich coffee aroma, and the taste was wonderfully balanced coffee bean with tinge of vanilla, and a pleasant finish with a slight kick (the balance finish kick is unfortunately from the acid).  I now added some whole milk, and as expected the regular coffee mellowed out a bit, but all of the wonderful flavor still came across. Incredibly when I added milk to the Puroast, it turned a poor tasting cup into an awful tasting cup. The flavor now became that of  mostly spoiled milk! This was such a strange sensation that I had three more people confirm the sour milk phenomenon. To top things of, the color had now become that of black brown mud.  So all in all, this was a bad experience. If you have a need to drink a low acid coffee do this. Get yourself your favorite cup of coffee and a bottle of antacid instead.
