I was thinking I would make a loose cheese cloth satchel, or have my wife sew up a couple for use, with draw strings and all. Then put zest of two baseball sized oranges, a couple stainless steel bolts, tie it up, and pour a little vodka over the satchel to sterilize it and the zest. I would then put that into the secondary 5-7 days prior to racking to my kegs. How does that sound for a plan? I know the cheese cloth may not be porous enough to let the beer pass through quickly, hence the reason for a bigger cheese cloth satchel for just a tiny bit of zest. At least the zest won't escape, and foul up beer lines, or dip tubes. How does this sound? Any feedback is much appreciated as usual.
