If I do this, I will use my 4L glass jugs with 65% or so, put in some charred strips, and freeze. Then put out on my deck for a couple of days, and repeat.
My question is if I put this out, and the sun shines on it, will this impart bad things into the flavor (clear glass bottles)? If so, I guess I could put the glass bottles inside of a box, to keep the sun shine off of them (might also be good idea to keep the neighbors from knowing or asking what is in the bottles

If people have experience with this process, please share it.
