Sixpacks are over $9 where I live, so the dollar-a-bottle back of the envelope rate for homebrewed brewskies is a real steal over the course of a year or so.
Another good move: become an inveterate bottle scrounger. Where I live glass recycling is kind of a chore, so offering to take bottles off the hands of neighbors and friends is appreciated. A win-win.
Would it be more economical to use bigger bottles like Growlers or Chimay size bottles? I would think it would be easier to reuse those. One of the small restaurant chains here has it’s own microbrewery. You can take their beer home as long as you purchase it in a Growler, that you can bring back for a cheaper priced refill.
