My CO2 tank spoiled and my main question is, can I safely drink the beer I carbonated with it? For background, I recently moved to India and when I packed my belongings the moving company said the only way to ship a compressed air tank was if it was empty and the valve was left open (which I surmise is the problem, but I’m open for other suggestions). The two tanks were open for 4 months. When I arrived I procured a different co2 tank locally and began brewing and kegging with no issue. Emptied the first tank and refilled it. No problems. When my shipment arrived 4 months after me, I filled my two tanks (that had the open valves) and kept brewing and kegging. And then I noticed my sparkling water was suddenly not good. It was gross. Like sweet sulfur. It took some deduction before I realized the smell was coming from the co2 tank. But my second tank was charging my spare kegs in the cold room and has the same problem. So I have 8 kegs that I need to dump for safety or keep with a possible off taste. I have been drinking the beer for 3 weeks and did not notice any off flavors and did not feel sick. I also didn’t drink the sparkling water often because my IPAs are really good. This led to a delay in noticing the bad gas. So, unsavory or unsafe? I would love a science answer.
