A kombucha entrepreneur made a major deal on the latest episode of “Shark Tank.” All the investor “sharks” wanted in on Kate Field’s at-home kombucha brewing kit. Two sharks offered Field $350,000 in exchange for 10 percent of her business, The Kombucha Shop. The kit sells for $45 and includes a reusable brew jar, a temperature gauge, test strips, brewing instructions and ingredients. (Inc.) (Photo from: The Kombucha Shop) https://goo.gl/4GjJhq .
