America's Test Kitchen - What Exactly is Tonic Water? | America's Test Kitchen
The video explores the importance of the letter 'T' in various contexts, humorously leading into a discussion about tonic water. A taste test was conducted comparing eight brands of tonic water, including four artisanal and four supermarket brands. The focus was on bitterness, a key characteristic of tonic water due to its quinine content, which historically helped prevent malaria. The test revealed that bitterness is balanced by sugar and botanicals, with tasters preferring a citrus-forward flavor. A black light test showed that the least bitter tonic had less quinine, correlating with its lack of fluorescence. The winning tonic, Polar, was praised for its balance of bitterness and sweetness, while Jack Rudy was noted for its lack of sweetness and quinine. Fentamon's was unique for its fermented botanicals, offering a distinct flavor profile.
Key Points:

- A black light test can reveal quinine content by fluorescence.
- Polar tonic water was preferred for its balanced citrus and sweetness.
- Artisanal tonics didn't outperform supermarket brands in taste tests.
