Glycol chiller and cooling jacket

Maybe I’m not using the right idea. I use big chunks of ice, and much less than 4 bags worth. I freeze two separate 2 gallon buckets the night before brewing. That way I have giant ice blocks ready to use.

I know the smaller the cubes, the quicker they melt… But even thinking about whiskey cubes… They’re large cubes that still get the drink nice and cold.

Maybe I just need to use smaller cubes… Or say screw it and build this glycol thing cuz it’d be fun.
