Coconut Water with a splash of Pineapple  This is refreshing!  It's sweet, but not too sweet.  The coconut flavor isn't pronounced, and the pineapple isn't so overpowering that it tastes like syrup.  It's clean tasting.  According to the packaging, "it has five essential electrolytes, more potassium than a banana, no fat, no cholesterol, and no preservatives."  There's a smidge of fiber, 0.8 g of protein and 16 g of sugars.  I suspect most of the sugar comes from the pineapple, but "cane juice" is one of the ingredients, too. The 8.5 fl oz carton comes to 75 calories.  If you sign up for subscribe & save, it's less than $1 per carton.  Actually, the carton is the only thing I don't like about this drink.  It's sort of hard to drink directly from because there isn't any air getting let in when you drink, which makes a vacuum.  This was solved by pouring it into a glass.  *whew*  This was good.  I will definitely get more, and I highly recommend this to people who like pineapple juice.

Maybe my tastebuds are different but I bought this at a local healthfood store and I'm not completely sold on it.  I tried it in my tea and it did leave me w/ an aftertaste...just like most sweetners. *shrugs*

Long ago I discovered that San Marzano tomatoes were unparalleled for flavor when it comes to making sauces. I tried many brands, and have done many side by side tasting comparisons, and Cento San Marzano tomatoes have consistently won out. These tomatoes have a deep and rich flavor, and a nice acid to sugar balance (though you may need to enhance this when making a sauce). It's pretty obvious when you pull these tomatoes out of the can that they were picked at their ripest, due to their deep red color and soft texture. Many tomatoes advertise themselves as San Marzanos, but since SM is a type of tomato, they could have been grown anywhere. Not these. These are SM tomatoes grown in the San Marzano region of Italy, in volcanic soils perfect for growing tomatoes. I have no affiliation with Cento, I just love a perfect tomato sauce. Use these tomatoes, be sure to not cook the sauce for more than 15 minutes, and you'll see what I mean. Even using fresh, locally grown, in-season tomatoes I haven't been able to get the depth of flavor that I do with the Centos.
