Um...when you put the cap back on, it's sealed. I high doubt they are putting nitrogen in the bottles, so there was air in there already. For the stash of Ultra I bought, they are capped more tightly now than when I brought them home from the store. Being open for a minute while I write down the FRN number isn't going to hurt anything.
