So I've been adding Raki To my airlock... It is a 90 proof distilled natural spirit ... Like Garapa, Anyways I just kind of topped it up (my airlock) And all of a sudden the top part of the liquid became very hazy and cloudy much like smoke?
I know it has absolutely nothing to do with the liquor, But what the heck happened?



This YouTube video gives you a real good viewing of what's going on...

https://en.wikipedia.org/wiki/Ouzo_effect maybe?

I've never seen it, I always drink my ouzo straight.

dilution with water turns raki a milky white - oils in spirit
fermentation produces c02 with h20 condensation
condensation moves through airlock, mixes with raki, you get milky white liquid
it's the top half because that's where the slots are located on the inner, upside-down airlock cup - the lower half of the liquid remains mostly undisturbed

Thank you stpug.... It's a really strange looking reaction. Looks like liquid smoke

Is it still going to be sterile?

Yes, certainly, at least until it evaporates... I still recommend Star San - lots cheaper.

Same thing happens if you add water to Absynthe (hence the Green Fairy effect) or Liquors like unfiltered straight from the still single malt Aberlour Scotch. It's oils and other things that may either be added to or not filtered out of the product.

It's probably the same reason why dry ice (frozen C02) fogs up. The carbon dioxide forms microdroplets with a liquid, in most cases water. Im assuming that if you use a high % alcohol in the airlock, the vapor will much more readily form a mist due to its higher vapor pressure.
