Ive seen some pretty interesting looking pellicles on some of my wild ales before I got into using oak barrels. This probably sounds stupid but in a way, I miss fermenting in glass because I cant really peep in and see whats up. So anyway, a year or so ago I decided I wanted to do a series of pellicle pictures to capture what these look like while they develope. When I pulled a wild ale out of my barrel, I racked about a pint into a growler and then I added some fresh wort. Below are the pictures I just found that I forgot about. First pick is at a month old. The rest of the pictures are taken every couple of weeks or so. I thought it was interesting to see that somewhere around the 6 month mark, the pellicle lost its white coloration and took on part of the wort color.
