Acai Machine is an aptly named drink, packing the equivalent of 178 acai berries into each bottle. It's noticeable from the very heavy, tart acai flavor. Also in this no-sugar added mix are grape, apple, banana, and plum puree/juices, which add some depth and thickness to the drink. Plus, it has the equivalent of over three servings of fruit. While it's a very drinkable flavor, it's a bit too thick for our liking; it's harder to drink than some of the other acai drinks that are out there. Still, this is definitely one of the better Naked entries in recent memory. Packaging is the classic Naked bottle, which has a very busy front panel and is, again, not as attractive as some of their competitors.
