Cymbopogon citratus = Capim cidrão = blue cachaça

[Moorea]

I was talking with an old distiller trying to get the recipe for a blue cachaça, and after many visits and many bottles drinked togheter he gave me the secret.
When he was filling the boiler with mash, he put some amount of Cymbopogon citratus (here in Brazil we call it lemmon grass) it add some very discrete lemmon taste to the cachaça and a unique blue color.
I checked it and the grass is also used from mosquito repellent !
I tried at home and it worked well, lets see if i dont die during the next weeks and them we can assure it is a safe recipe (smiles)
But, keep jokings aside, the blue cachaça is still famous on Paraty and other cities and finnaly i got the trick.
If someone else has used some kind of grass on the still please let m know

my best regards
