If there's a lot of temperature variation in your house, this can result in very messy leakage (how many times have we got honey on the counter this way? Too many!), if you turn the bottle upside down, and then it warms up, the air inside will expand, and even if the lid is on securely, sometimes the internal pressure will still push the contents out through the cap. You can avoid the mess by upending the bottle over a cup or jar (custard cups are good for this), or by sticking it in the fridge.
