moreto62,

About 2 weeks ago, in a conference, the interior price at the miller's door, ethanol was quoted to be 960 reals per K tonnes or 96 reals/liter ( w/o tax or transportation).

So the retail price of 155 -170 reals reflect anice mark-up for taxes, transportation and distribution.
Just a data point I was interested to get as ense for since CZZ is at both end of the business.
