Received in a timely manner and in good condition. My Mishka is a little spoiled (I cook her meals when I can afford it, buy her wellness kibble when I can't) but she ate this willingly. I bought this because it qualified for overnight shipping, unlike the much heavier wellness bag, and she was almost out of kibble. I'm happy with the compromise.

Zen brews up to an golden amber liquor. The aroma is sweet spearmint. The blending of this tea is excellent--spearmint could be overpowering but they use just the right amount of it. Slightly sweet spearmint is the primary flavor, then you taste a hint of lemon. The green tea provides an herbal base for these two flavors that makes the intial impression of zesty spearmint and lemon modulate into a substantial potion. Very nice and satisfying with a clean spearmint aftertaste. Remember that this tea does have caffeine--however, it does not say how much on the box. A good estimate might be 30 mg--compared to 90mg for the average cup of coffee. Make sure you time how long you brew this tea because if you brew too long it becomes bitter. Four minutes is ample.

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.
