Airing Losses Experiment

Lloyd

With one of the Baby Dragon glass parrot prototypes I created a simple experiment to record the losses due to airing the product. My thermometer only reads in F.

Day 1 Alcohol 57% => 60.5°F
Day 2 Alcohol 55% => 59.0°F
Day 3 Alcohol 54% => 60.0°F
Day 4 Alcohol 51% => 60.0°F
Day 5 Alcohol 46% => 64.0°F

I don't know the relative humidity and I know it has a big affect but just don't have that info.
The alco is difficult to read in the pictures but the loss of alcohol, both in %ABV and quantity is evident by the results and the drop in product in the parrot. Quite the Angels Share!

Day 1

Day 3

Day 4

Considering I lost about 10% ABV in only 5 days is quite a lot.

I'll let this experiment run for another week and report back.

Haha, I'm a 'The shotglass is half full instead of half empty' kinda guy :))

You should also weigh the liquid so you can determine how much water evaporates as well.

Easier to calculate by the mouthful I find.

Over the last week the ABV has dropped to about 42% and seems to stay there even though the total volume keeps dropping, suggesting that both alcohol and water are evaporating at about the same rate.
