    Rosin used in roasting?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi local cofee experts,

    Someone in my household has come down with a serious allergic condition. *After the patch tests at the dermatologist it has been narrowed down to one or two substances. *One is Rosin (colophony) that is used as a polishing agent for roasted coffee beans. *Well the only coffee beans in our house come from small local roasters in Brisbane (oh and the bag of Espresso Wow! we are just finising off). * Before calling all of the roasters up individually does any one here know if it is likely that Rosin is used in small roasting operations in Australia?

    Thanks, Cindy P

    Until your post had never heard of that. A google turned up over 600 hits! If the coffee is the source, then I would suggest finding a dependable source of green coffee and getting a home roasting setup. I wonder if there is an easy test for that on the coffee beans. it would seem an odd thing to do to coffee and fairly well pointless IMO.

    To put them next to the waxed fruit in the supermarket?
    So that they look like theyve just been roasted for longer?
    Mr Sheen works too :-? :-? :-? :-? :-?

    Randy G, MarcS, YeeZa, *These are the responses I was hoping for - you hadnt *heard of it before this. *I think that if anyone is going to polish their roasted beans then it isnt going to be the specialty roasters around here.

    Javaphile, *I didnt think to look at Wikipedia but got similar information from some other allergy sites. *Coffee is only one of the things we are looking at. *We would like to remove it from the list ASAP since I would hate to have to drink my coffee alone in the mornings - or else start on double shot drinks.

    If anyone has heard of the use of rosin on roasted beans in Australia Id be interested in hearing from you.

    Hi Cindy,

    As Java-who has middle name for every occasion- phile pointed out, there are quite a few other more common uses for Rosin that are more likely to be the source.

    I dont know where you got the info that it is used for polishing coffee beans, seems highly unlikely in this country,
    positive that Andy wouldnt do it....

    Good luck with your search for the real culprit.

    Regards
    Bullitt

    Some companies do indeed polish their beans. There are bean polishers made to do that exact thing. Its pretty unlikely though that any small specialty roaster would be doing it though. :)

    As it happens,

    My youngest son and I both display a high sensitivity to resin/rosin (as smoke, dust or dissolved in a solvent) and in all the time Ive been a coffee [s]fanatic[/s] aficionado, have never experienced a bad reaction to specialist roasted beans. Really does make you wonder which companies would be doing this? :-?
