This is my first time using star san. I mixed 6ml (right above the 5ml line) with a 1 gallon jug of distilled water. filled my sprayer. tried spraying something...and say almost no foam.

There was a little bit, but it slid off the the bottle I sprayed and the foam bubbles dissappeared very quickly.

Is this normal? When I spray the outside of something, like a normal glass bottle, should I see a crazy amount of foam that will stick to the glass?

6ml is plenty for 1 gallon. The spray nozzle knocks down a lot of the foam I've found. Even if there's no foam don't worry it's still doing it's job.

If you shake the bottle does it foam up a lot inside?

Star San mostly foams up if you add water on top of it. Like if you put one ounce in a bucket and fill 5 gallons of water on top of it you will get a lot of foam. If you instead fill the 5 gallons of water first and then add the Star San you will get no foaming - at least I don't. Not sure about the spray bottle thing but I wouldn't care about it. And yes, like Earwig said, if you agitate it a lot it does foam.

In my experience, you don't get foam unless you agitate it. When I'm using my vinator with starsan, it foams like crazy. If I shake my spray bottle, same thing. When I add ~6ml to a 1gal distilled jug or when I use the starsan solution in the spray bottle, it doesn't foam.

Why do you want foam?

Don't think he wanted foam per se, but rather wanted to be sure it was working correct since so many people talk about the foam.

The foam is helpful to covering some stuff where the liquid doesn't always get. It's not all that useful IMO, but not seeing it can be a sign of maybe not mixing it properly, which is why the OP posted I think.

I see very little foam when spraying from a bottle. Mixing with water and shaking in a carboy makes a lot more foam that sticks around until the carboy gets filled with beer and the foam comes pushing out the top.
