PROBLEM: I roast at home with a stove-top popcorn popper (but I do it outside, of course). These beans (Coffee Bean Direct Green Mexican Altura) seem to be well-suited for this method. The first and second cracks are distinct, and I've roasted the beans from medium to slightly dark with great results every time. The aroma is strong and persistent. The taste is smooth, velvety, yet lively. 
 Polarity: Positive

SOLUTION: True

PROBLEM: This is the best tasting stevia powder I've tried. Most other powders have a weird after taste but this one doesn't. I recently bought a 5lb bag of it online and I'm making my way through it. 
 Polarity: Positive

SOLUTION: True

PROBLEM: Bought a pack of a 100 of these and each cup it takes so long to process the coffee.. Each cup I get coffee grounds in and not a whole cup of coffee.. Great concept, I believe the paper filter is to fine which holds back the coffee and pressure which results in bleeding of coffee grounds out of the 2 other holes.. Regular K Cups work work much better.. Again great idea, just not so great of a product.. 
 Polarity: Negative

SOLUTION:
True
