Not sure if that's on-topic, but I'm converting an old barrel into a tap system. Essentially a Keezer, except that I don't like something that still looks like an appliance - a barrel is just more authentic.
The problem: How do I cool the kegs inside? Since it's not needed to be permanently one (it's for a weekly or biweekly event), I could just dump in a bunch of ice every time I need to bring out the bar, but I'm lazy and that's boring :)
I know that there are heating spirals, but I wonder if there are cooling spirals or other flexible ways that I just plug into a power outlet and have it cool my two 5-gallon kegs?
