Fire and Ice Ocean Sour

Follow along to disrupt perfect ocean conditions with this cocktail featuring blue Curaçao, lemon and ginger topped with soda water over ice​

A Taste of the Story

Rising acidity, temperatures and water levels are dramatically changing ocean dynamics, shaking up life in the sea.

Prior to the start of the Industrial Economy, ocean conditions had remained relatively stable throughout the 7,000 year Holocene Era. However, since then, oceans have absorbed about 28% of the CO2 produced by human activities. CO2 reacts with sea water to produce carbonic acid. As a result, in some areas ocean pH has lowered as much as 8.15 to 8.05, which equates to a 30% increase in acidity. ​

This change in balance of minerals makes it more difficult for corals, some types of plankton and other organisms to produce calcium carbonate, which is the main ingredient in their hard skeletons or shells, which threatens their survival. ​

In addition, the ocean has absorbed more than 90% of the extra accumulated heat energy resulting from higher greenhouse gas levels. This extra energy is warming the oceans, especially in the water closest to the surface. Globally, from 1971-2010, the upper 75 meters of ocean warmed an average of 0.11°C per decade. ​

During this time, sea levels have also risen an average of 10 inches due to warmer temperatures melting ice, which runs into ocean waters. ​

To experience these disruptive dynamics first-hand in cocktail form, follow the steps below:

method

  1. Start out by making the perfect ocean base from a combination of ½ oz gin/vodka and ½ oz blue curacao in a martini glass or glass of your choice​
  2. Next, take those pre-Industrial ocean conditions and add acidity by introducing carbonated water with a squeeze of lemon juice​
  3. From there, warm the mixture with a splash of ginger juice​
  4. Lastly, add 1-2 ice cubes to watch the waters rise​
