Lemon oil

This may sound kind of gross, but I just drank out of a water bottle left in my craft room from a couple weeks ago.  The water tasted great.  Thanks to the one lemon doterra oil drop I put in the water.  I often put a drop of the oil in my water to make it taste good, but today got me thinking, lemon oil could come in handy if we have to drink the water we have stored.  The water in my craft room was only weeks old, not months old like the water in my storage room, but I think the lemon made it taste fresh from the sink.
