For the past four years of DIY, I've been keeping my nic (and flavors) in an empty cooler in my basement. I just opened a new bottle that had been in the cooler for three years, and it's perfectly clear. I imagine you would be fine for a year, especially if you have the Armor and don't open it. The only bottle I have that oxidized was a liter of 100 mg/ml that I didn't split. It took me a couple years to work through it, and by the end it was pretty iffy, but vapeable (for me anyway). Waste not want not!
