While you old pros out there can accurately meter out the perfect amount of alcohol, I have been having troubles in the field being consistent and accurate. I tried metering out capfulls and keep spilling on my hands or gloves. I found a bottle that might work pretty well as it is designed to dispense 10 ml. Most of my trips will be 3-5 days in duration and with my wife.

Let me know what you think. The mouthwash cost ~ 4 bucks and I have seen other backpacking bottles with 1/2 ounce dispensing but they seemed small at 4 or 8 ounce (and they cost more money).
