Re: I didn't think sesame oil was brown..

Olive oil always comes out the same color.  Might be once in a blue moon you hear of it being clear from any pullers (I think I have only read one person say it was clear at the end of the pull).  I have been using it for four months and it has never been clear.  It also takes a lot to thin it - it is a much thicker oil than the others.  There are a lot of times when I pull it does not thin out  Also, this foam you are looking for would simply be from the swishing action.  It is not necessarily any tale-tell mark of a good pull. My oil is rarely foamy.

Expeller-pressed sesame oil (what many are using on this forum) is also usually fairly light in color,  and it takes little to turn it white.  Same with sunflower.
