I first use win 50 from some labs and am interested in brewing my own, so i got raws. I did some research and find some guys used 3% guaiacol as ‘super solvent’ and 100% Ethyl Oleate and for a Carrier oil in all of their products. I’m sure it was to avoid crashing issues when being shipped overseas. But I have bad reaction to too much EO. I would get major knots and swelling Pip. The recipe did reduce the Amount of Pip but I was getting crashing issues. The gear would hold well until I broke the beaker seal and cool down, slowly the gear would start to crash from small crystals floating around like snow flakes to completely crashed over a short period of time. Hopefully the miglyol 840 recipe works. I will be sure to let you guys know.
