Homebrew Mint Extract

I clearcut a stand of spearmint and turned it into three jars of what should become mint extract:

Homebrew mint extract - start 2021-06-17
Homebrew mint extract – start 2021-06-17

The left jar has 3 ounces of mint mostly covered with 80 proof vodka and the other two jars each have 5 ounces submerged in 180 proof grain alcohol.

Nine days later:

The vodka is now on the right and shows a weird layering caused by the leaves extending above the light yellow liquid; I’ve been inverting the jars every few days. The grain alcohol looks more like the previous iteration, with uniformly decolored leaves in dark green liquid.

A closer look:

What’s happening in the vodka jar does not look like a nominal outcome …

  1. Certainly interesting. Maybe a chemist can comment? Or at least someone who had more chemistry than I did.

    1. I can’t imagine anything normally feeding on mint leaves that could survive in vodka, but imagination has never been my strong suit.

      Plan: unscrew the lid outdoors at arm’s length.
