Tomorrow I plan to bottle up a few Belgian beers I have in the keg using a Beer Gun.  I was wondering if adding ice to my water/star san santizing solution would present any problems.  Rather than sanitizing then putting the bottles into the freezer/fridge, I hoped to get my sanitizing liquid as cold as possible.  I've found in the past that trying to bottle higly carbonated beer through a beer gun into room temperature bottles results in excess foaming.  Any issue with putting ice into Star San and Water to bring the temp down?  Will Star San not be effective?

As the ice melts, the concentration will  change.    Could you just make up the star san ahead and refrigerate it?  Then you'd know it's full strength.  Unless you're calculating the amount of water in the ice, and looking to get the correct dilution when all the ice is just melted.  I agree everything needs to be as cold as possible.  It just seems to me that chilling the bottles is still simplest.

I make a 5 gallon bucket of starsan using cold tap. I submerge about 6 or 8 bottles in it. I also use the starsan bucket to set my beergun in when I'm doing other things. Dump, fill, cap, repeat. Add more bottles, repeat. Seems to work just fine.

Why not stick a jug of star san into the fridge with the bottles?  Only pull out a case of bottles at a time, so they don't warm up. Replace the sanitizer with cold with the cases.   Depending on how you sanitize, it shouldn't be too difficult.  I use a sulfiter to sanitize so I'm only using a quart to sanitize my bottles.
