On the Washing of Tea

The Gastropod podcast “looks at food through the lens of science and history”, so it’s only natural that they’ll cover stuff relevant to our interests here at Doing Science to Stuff. The May episode The Cocktail Hour provides a fascinating look at not only the history and craft of cocktail making, but also some modern techniques for enhancing the cocktail experience.

Initial observation:

Toward the end of the episode, they discuss a technique called boozewashing. The fundamental idea, expanded upon in Dave Arnold’s Liquid Intelligence, is to use chemistry to pull undesirable flavors out of a drink. In this case, using proteins in milk to pull polyphenols like tannins out of tea-infused vodka.

I had thought to myself, that surely, I would have a chance to hear this great man again, and that missing this one university event wouldn’t matter too much to me.

So. To honor the anniversary of the birth of Douglas Adams, our first science experiment regards, in part, the thermal properties of a cup of tea.
