UV is short-wave. Infrared is long-wave. Although really its high(UV)-low(IR) frequency of the waves.

I never referred to UV as long wave, rather I was mentioning the longer-wave UV region near the visible part of the spectrum. AKA near-UV. Length is all relative I suppose, like a taller short guy

So what ended up being the final outcome? Were your beers badly skunked?

Hopefully it turned out ok. Skunkiness varies along with one's preference or distain of it.

I actually deliberatly skunked bottled beer by exposing it to summer sunlight for relatively short periods of time in transparent glass bottles. I was aiming for a heiny corona thing with a frankenstien grain batch that required a mix of several adjunts. I dont have my notes i front of me but recall skunkiness set in after a few minutes.

Primary :
On Order: nothing at all..for a few months
Thinking about: Plisner malt and saaz hops

I like the experimentation going on here! Did the other carboy skunk? The light is def a high possibility but there could have been an infection that set in someway as well. Have you set a lot of carboys in that space and had this result bf?

I second the wrapping in a towel. it's what I do with my beers, especially if they're going to be in there for a while.

Yes, welcome to corona brewing! they skunk it on purpose. The clear bottles they pack it in does this and It is one of my favorite beers! I tried to skunk one but it didnt work. there is a scientific answer to your post, but im not a scientist, but atleast it isnt an infection , just a process for people that like it that way.

Get a cheap fridge and build the aquarium temp control. Two birds with one stone
