Nah, it's created in a process whereby the fungal excretions of sandtrout mix with water to form a pre-spice mass. This mass would then be brought to the surface of the desert through an explosion of pressure, and under the intense heat and air of Arrakis, melange would form. When the worms died, sandtrout would be released into the sand, and the cycle of creation would repeat.
Then you steep it in vodka for a few weeks and you have a spice tea.
In all seriousness though, just get some cheap vodka and steep your spices in it and add it to taste at either secondary fermentation or at bottling.
