Just got done filling a keg and was surprised the 5 gallons wouldn't fit. Here I left about 0.25 gallons of starsan in the bottom of the keg and siphoned the beer on top of it. Is it safe to drink, or did I just ruin 5 gallons of beer? Has anyone else done dumb something stupid like this?

Pretty bummed out right now. This is the first time I have ever made a mistake like this.

Wow? How did you miss that much Star San?

To be honest,I've never heard or read how long it takes Starsan to break down into yeast nutrient. That's the 64 dollar question here.

Oops...

I've heard that StarSan breaks down into a yeast nutrient that is safe to drink, but I don't know about that kind of quantity.

I'd recommend emailing 5 Star and verifying, but I think it's safe. Probably watered down your beer a noticeable bit though :/

I'd like to ask them sometime about how long it takes to break down,& the details of that as to quantity,when mixed with beer,etc.

Looks like you guys are in luck and I will report back once I find out. My only option is to call, or dump the batch. Dumping is a last resort, so I will doing some research.


I dumped about 0.5 gallons off the top of the keg. I can hope a majority of the solution was concentrated in the top since I fill from the bottom of the keg, but I doubt it. Then I finished racking the remaining beer in the carboy into the keg.

Damn that sucks.

Since most of the yeast activity has subsided, I doubt they would metabolize any Starsan at this point, and certainly not that amount. I've had my airlock contents added to my beer a few times and could not detect those small amounts (1/2 - 1 oz) in a 5 gallon batch. But a quart of it is a considerable amount.

+1 on an email to Starsan.

As of tasting Starsan. I've taken some very small sips of it (teaspoon quantities) just to test, and I can taste it, by itself. On my palate it has a slight metallic taste. I bet it is easily masked in beer, except maybe the very light ones.

Healthwise I would be most concerned with ingesting larger quantities of the surfectant component rather than the phosphoric acid one. But we're still talking small amounts, given the dilution ratio of Starsan's working solution.

I just read thread from a guy who did the same (1/2 gal starsan solution in a 5 gal porter) and apparently scored a 38 with it in competition.
