I had heard of the practice before when individuals have wanted to use real ingredients instead of using extracts in their beer. The general sense is to get the taste of something fatty inside your beer without going through the normal troubles. Fats and oils tend to ruin head retention, and more importantly facilitate a rancid beer. Hence why you can't just throw something like bacon into your boil and expect everything to go off without a hitch.
Of course, as everyone knows (or the 2 people that read this blog), I decided to embrace my American roots and include bacon in my beer. I can't take credit for going about this alone as I tried to follow what "Ryan Brews" did with his hot wing beer. Unfortunately, I am still an idiot and did not see the more comprehensive steps he laid out before trying my first experiment. I won't go into too much detail as he seems to be able to explain the process much better than I, but I will point out some differences in my approach that I will be changing in order to better match his.
I went out and bought some apple smoked bacon and quickly cooked three strips. I wanted the distinctive applewood bacon smell and taste, so no big surprise here. Afterwards, instead of adding the fat to the vodka, I added the actual strips. I had read somewhere that this was a good way to make your own, but after observing my results, I believe the fat may impart a much strong smell and taste (It is the fat that the alcohol interacts with and just the strips leaves less fun in the glass).
After placing the strips in the glass, I let it sit for one full day. I would have let it sit a little longer, but I was at my parents doing all of this and needed to leave. Isn't procrastination fun? Anyways, the liquid looked a disgusting murky brown with small chunks of meat suspended in the glass after becoming dislodged from the strips. I removed the large strips and placed the glass in the freezer. As everyone knows (well, I'm hoping for the sake of our education system), alcohol has a lower freezing point than water. As a result, the fat on top of the glass will freeze and the alcohol will be left alone beneath it. After this, the fat was broken through and put through a coffee filter for good measure into another glass. I didn't have the time, but I would highly suggest repeating the freezing process at least a couple of times. Fat in beer = sad face when trying to drink beer.
I will update with my second attempt when I get around to it. Also, apologies for the blurry pictures of the filtered bacon vodka. They are a product of my father. Apologies as well for this post that is most likely riddled with errors. It is a product of me. I could edit it, but I just don't care.
