I had the beer tested. Any one else have issues with US-05 dry yeast?
Here are the results we got:
LCSM(wild yeast media): 1 colony of growth. After looking at it under the microscope, it didn't look like wild yeast but pretty standard. Normally wild yeast will get elongated, but this didn't look off.
SDA aerobic: about 40 colonies, Gram positive catalase positive, rods. This is sounding like a non-beer spoiler bacillus.
SDA Anaerobic: 1 colony, Gram (+) catalase(+) rods. Clearly not happy in the anaerobic environment.
HLP(selective for pediococcus and lactobacillus): no growth
Hope this helps you. From the growth we got it doesn't look like a beer spoiler.
