What type of Butane should I be using for my Essence extraction?

We at Shell Shock reccomend Colibri or Iolite Butane (which is essentially Colibri) 

If you cannot find Colibri try to find one of the butane brands listed. And by all means avoid Ronson, Bernz-o-matic or other butane not listed below, they add smell to their butane and this smell is left behind making the oil taste very bad.

Other Brands that are good to use: 

COLIBRI, NEWPORT, CORA, CTC, COLTON, DUNHILL, DAVIDOFF, FACKELMAN, WIN, NIBO, SAROME, CALOR GAS MATCH, UNILIGHT, K2, SUPERGAS, VENTTI, VECTOR.
