[EX Q]: 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.
[EX A]: Negative

[EX Q]: I was really excited and surprised when I found this mix in my local Wal Mart. Given it was a good price, I figured Id give it a shot.... before I whipped up a batch I figured Id do a little investigating to see if there was any input/ suggestions on the mix. WOW. Is everyone using the same mix or what? Reviews from "its great" to "its horrible"..like a total 50/50 split. SOOOooo, before  I wasted a bunch of money on products to whip up a batch and see for myself, I figured Id simply open the packae up and take a taste to the mix, all on its own.... ummmmm, yeah. It TOTALLY has a pretty strong bitter after taste. :/ And , like another reviewer, I had figured this mix would be adequately sweet enough for me and not need any extra sweetener (I dont like things very sweet, at all) but its DEF not. As I re read the ingredients I realized there isnt ANY sugar/sweetener in this mix so, youd def NEED to add sweetening. But, overall, I dont even plan on taking this mix that far. Im pretty certain that adding sugar wont take that aftertaste away. Thats an issue with the flour mix and no amount of sugar is going to make that go away..... Id strongly suggest avoiding this mix.... I hope the company works on this mix. It has good elements to it (I like the fact you can determine how sweet youd want it and the apple pieces are pretty tasty) and I think it COULD be really tasty.
[EX A]: Negative

[EX Q]: I am so please that I was able to get the tea from Amazon.  I was pleased with the service.  Sinus Buster Herbal Tea is very helpful and it gives me great relief with my allergy.  I have been suffered with Hay Fever Allergy for the past 20 years or more.  First time I find a medication which is natural and no side affects compare to other medication for allergy.  I discovered the tea at a farm market in PA on a bus ride with my church.  At first I was hesitated to purchase the tea, but somoeone who was in the same but I was, told me to buy the tea because she used it a year ago, and got great relief from it with her allergy.  Thanks,  MC
