Found a bit more info on the beverage and i'm planning to make some fairly soon. Below is info I found using the video provided as a starting point.
This is an excerpt from Le Menagier de Paris
(France, 1393 - Janet Hinson, trans.)
The original source can be found at David Friedman's website
BOUCHET. To make six sixths of bouchet, take six pints of fine sweet honey, and put it in a cauldron on the fire and boil it, and stir continually until it starts to grow, and you see that it is producing bubbles like small globules which burst, and as they burst emit a little smoke which is sort of dark: and then stir, and then add seven sixths of water and boil until it reduces to six sixths again, and keep stirring. And then put it in a tub to cool until it is just warm; and then strain it through a cloth bag, and then put it in a cask and add one chopine (half-litre) of beer-yeast, for it is this which makes it the most piquant, (and if you use bread yeast, however much you like the taste, the colour will be insipid), and cover it well and warmly to work. And if you want to make it very good, add an ounce of ginger, long pepper, grains of Paradise and cloves in equal amounts, except for the cloves of which there should be less, and put them in a cloth bag and throw in. And after two or three days, if the bouchet smells spicy enough and is strong enough, take out the spice-bag and squeeze it and put it in the next barrel you make. And thus you will be able to use these same spices three or four times.
