Lis and I have been talking for a while about making our own vodka infusions, but this post got me thinking about other things I could try. The one I was most excited about finally putting into practice was peppercorn vodka. We've developed a recipe that would call for this, should it work out. I'll let you know how that goes.
My other raw ingredients were coffee beans, blueberries, and peaches. The coffee went into whiskey, the blueberries into gin, and the peaches into vodka. I used old jars I found in our garage and at an antiques/junk store. Mason jars work the best, as you can seal them very tightly and be able to shake them once a week without anything spilling.
