Made a couple small batches of winny, each time I had to let it sit for several days after the first time heating and then re-heat to get to dissolve. It would dissolve the first time heating but would only stay in suspension for a few hours. The very first batch I let sit for several weeks after the raw separated from the disolvents. I decided to re-heat it and added a slight bit more bb to help it hold in suspension, it worked and held fine. It had no pip and I like it a lot. I tried it a few more times using the same process, but not allowing it to sit as long and everything worked out fine. I followed PG's receive to the T, so I know this could not have been the problem. Could re-heating it harm or degrade it in anyway? When I re-heated it, it turned a darker color but when it cooled got lighter. If this has happened to anyone else please let me know.
