Coke is backing the launch with a marketing campaign that includes a TV ad debuting on UK screens on 1 May.
The company said Oasis Might Drops is designed to "bring teens and young adults to the [Oasis] brand".
The product is part of a broader redesign of the Oasis brand, including an overhaul of the visual identity, new pack design and product development. The latter includes a new Oasis variant called Oasis Pineapple Rush.
Oasis Mighty Drops will be sold in 56ml packs in Mixed Berry, Mango and Raspberry Lemonade flavours and backed by a TV commercial that will take an "amusing look at overnight celebrity culture". It can be added to water while "on-the-go".
The packaging is designed to fit easily into consumers’ handbags or gym bags.
Oasis will compete in a market dominated by Robinson’s, which earlier this month promoted its own on-the-go product Squash’d with a stunt involving the VFX team behind hit film Gravity drinking in zero-G.
