I have been asked by a friend to bring a few bottles of alcohol with me (from the US) when I visit Colombia this month (November 2016).  After [some][1] [research][2] I have found that I can bring "*two (2) bottles of alcoholic beverages*" into Colombia, but I have been unable to find the maximum size of bottles or total volume allowed.

**Is there a *maximum size (volume) restriction* to the bottles that can be legally brought into Colombia (I'm assuming 'yes') and, if so, what is the size restriction?**  

Bonus points if you can reference a source.  ;)
