First into the tank are Nikita Salmon and Chas Smith of Sap!, seeking $600,000 for 12 percent equity.

Sap! is a new kind of beverage made from tree sap. According to their website, the “plant-based superfood sparkling beverages [are] made from 100% pure maple and birch sap straight from the forests of Vermont.” Flavors include birch sparkling, maple soda and maple seltzer. A 24-pack of maple water costs $38.99 and the beverages are available in a plethora of stores in the Northeast and online.

The sharks like the flavors, but Robert Herjavec and Mark Cuban don’t like the taste of the birch sparkling. They have done $400,000 in sales to date.

Cuban likes the health aspect, but finds their marketing problematic. He goes out, followed by Barbara Corcoran. Lori Greiner likes the products but goes out. Herjavec then decides to offer $600,000 for 30 percent. Guest shark Rohan Oza struggles with the “why” and goes out. The duo counters Herjavec at 20 percent, which he declines. He goes out, leaving them without a deal.
