Making My Own Bourbon

I let the "first fill" drop down until this month and rotated to the garage instead of the house this month. The level was so low after the summer aging that I went ahead and added the other 750ml of single malt and 32oz of cold spring water to top it off! I'm hoping a lot of the first 32oz of spring water become the seepage and Angel's share in the attic. Next month I'll leave it up in the attic until January 1.
