I know most everyone that bottles reuses bottles from craft beers purchased, but what other things have made their way to your brewing area? What do you grab before the wife makes it to the trash can? Here are a few I use:
Pretzel tubs: Get them at Sams or Costco. Use them for holding grain for a specific batch until it is ready to be crushed. If doing multiple beers, it is nice to keep them organized until ready to brew. The big ones will hold around 14 or so pounds of grain easily. One thing done prior to brew day!
Spice jars: Work nice for flavorings after they are opened. I will cut the label describing what it is and tape to the jar.
Margarine tubs, others: weigh boats for grain when making up a recipe, dumping pot for bottle dregs (no sink in shop), nice for when cleaning to carry some cleaning solution around.
I also catch my wort chiller water in tubs. It is nicely heated so I have a couple tubs for cleaning everything without wasting water or having to run more hot water.
So what else? I know I have others; just need to do a brew day to see stuff in action to remember. What do you use? Money saved from reusing is more money for home brewing!
