Funny you should mention clear coffee. Remember Crystal Pepsi? Back around that time, my better half was working for the company that owned (amongst many other things) one of the US's best selling coffee brands and came up with how to remove all the color from coffee, without changing its flavor. Given how Crystal Pepsi and Tab Clear were not the biggest marketing sucess stories in history, maybe it's just as well that this idea didn't go any further than the drawing board.
Anyway, to make myself a little more clear, I didn't filter the maceration. After letting it brew for 48 hours, it was diluted and the whole lot dumped in to the airstill and redistilled. I threw the copper scrubbers in there from force of habit. I usually include them in the still as a boil enhancer, although it really wasn't necessary for this run.
The recipe I used for the Trappistine was a scaled down version of this one from Brannt and Wahl's "The Techno-Chemical Receipt Book":

10g wormwood
10g cardamom
10g angelica root
20g mint leaves
7.5g lemon balm
5g myrrh
5g calamus root
2g cloves
1g cinnamon
1g nutmeg (figured it was close enough to mace)
The herbs and the roots were all home grown and I just happened to have all the spices in the kitchen.
This was macerated for 48 hours in 1l of the best neutral I could produce - slightly lower than the 85% specifed in the original recipe. This all got dumped into the still and I collected one liter at about 76%. Colored it with saffron (I skimped a little, because it's so darned expensive, but it still colored it well), then added about 750ml water and 450ml sugar syrup to bring it down to about 35% and enough to give me three 750ml bottles. I think it needs to age a little, but the little taste I took was very promising indeed. I was concerned that the cardamom might be a little past its best, but it is definitely making its presence known!
I couldn't find any of the real thing for sale online, so I don't know how much money I saved with my imitation.
