Love this water! Here's why!
Size: 42.3 Fl Oz (Pack of 12), Number of Items: 12
I am pretty picky about bottled water. I will only drink black capped water as white caps make me very ill and blue caps don't have the taste or quality of black caps (the color of caps indicate how it is collected and process). Of all the black caps, Essentia is my favorite brand. I love the strong, sturdy bottles, and prefer the larger size to help me remember to hydrate. Most people don't feel like water has affects like coffee or energy drinks, but this water is clean and provides me with a boost of alertness.
In terms of the value, I think it's definitely overpriced. I don't believe water should come at such a high price, yet I still pay for this brand because of the taste, the enjoyment, my energy levels and how clean it tastes going down. And it doesn't make me ill.
If you're new to understanding water, pH balances, and how water is different based on how it is processed, give this a try and experience the difference of it's effectiveness.

Good Water

Good price. Love this brand of water - no after taste. We even use the water in our ice maker :) as well as making lemon and cucumber water for hydration and a refresher.

My Son's Favorite
Size: 42.3 Fl Oz (Pack of 12), Number of Items: 12
My son loves Essentia, and it's the way I can get him to drink water instead of sugary drinks. Essentia puts together an attractive package, too. The black boxes are instantly recognizable, and the bottles actually in drink holders in our car, making portability a big plus, for us, considering he goes around with a bottle most everywhere we go. For him, he says it's the best-tasting bottled water on the market, and its quality is instantly noticeable in comparison its competitors. It keeps him hydrated, and he prefers it to such a degree that we've started buying it by the case.

Expensive but good tasting water
Size: 20 Fl Oz (Pack of 24), Number of Items: 24
Expensive but good water. Crazy thing was how it was shipped. Shipped in a box like three times the size of the case the water came in. Didn't have any packing materials inside this huge box to keep it from sliding around. Box arrived halfway opened.
