NICE! That makes for a hell of a lot of bottles that'll need filling. You might want to make 20 gallons or so of Apfelwein and start a pipeline ha ha ha. Have you decided on which wall in your home you'll be devoting to the storage of all these bottles? Or you could make... a wall...
IF you have a college/university/large hospital near you, find out when they have a surplus auction. Supposedly, filing cabinets like these go for ~$20 ea.
Good score. I think. After 100 bottles you might be looking to upgrade to a two keg system.
I'll have , 5 gal wit, 5 gal oatmeal stout, 5 gal honey brown clone that will need bottled in the next week....then 10 gal batches of brown, apa, and scottish/80 shilling, in about 3 weeks....plan on using a bunch of these soon!
