Moonshine?

I swear our neighbor just had moonshine delivered to their door. Child and I are leaving this morning for Wyoming for my grandmother's funeral, so I was up early packing things in the car. A flatbed pickup truck pulls up in front of our fourplex, and an old man in jeans and a jean jacket gets out. He walks around the passenger side, opens the door, and pulls out two quart Mason jars of clear liquid. He nods and walks towards our neighbor's door, while I head back inside. As I look back, I can see into his truck cab, and there's several more quart jars, along with a few gallon jugs. What other clear liquids get delivered in quart Mason jars? It has to be moonshine.
