Welcome into the first of what's going to be three videos on capturing and purifying wild yeast. This is originally supposed to be one video, but I ended up with just too much video, so I split it into thirds. If all you're interested in doing is lambic-style brews using sort of the natural bacteria and yeast growing in your neighborhood, this is the only one of the three videos you need to watch. The second and third video are going to talk about how to purify individual strains of yeast or bacteria from a lambic style or a cool ship style beer in order to then purify them into pure strains for future use. So in this video, I'm going to cover two different ways of capturing yeast. One using sources such as vegetables or fruits, and the other using just yeast and bacteria captured from the air. So I forgot to take video of the capturing yeast off of fruits, so some pictures will just have to do. To collect yeast off of sources like these, you need to first pick stuff that has a good chance of having yeast, and that would be anything that naturally contains some sugar. So that could be flowers in the form of their nectar, honey. Believe it or not, deciduous tree bark because there tends to be a lot of sap inside of these trees. Of course, any fruit and any sweet vegetable. These are all good potential sources of yeast. You then collect them into some sort of a clean container. This is in my case, I use centerfuge tubes, but you could just as easily use a small jar like a baby food container that you could clean quite well. Then you want to put a clean wart, fresh wart into that tube, and let it sit and let it begin to ferment. Now when I did this, I made a Kierer, and that was, I didn't remove fruit that was floating at the surface, and so I lost a few of my tubes to mold this started growing. So if your fruit start floating, make sure you're removing that promptly. Now your second option is to try and collect yeast from the air. So the way I set up this particular yeast capture system is pretty simple. In this pot, I have a little over a cup of 10 IBU hopped work that I prepared a while ago and just froze until I needed it, and I'm obviously boiling it to sanitize. In this pot, I'm bringing to a boil in order to sanitize a mesh bag. In this case, this is a bag for making jellies, and as well as a 500 ml, so roughly a one-pink mason jar along with the screw lid and the vacuum cap. So these then get assembled. I squeezed the mesh bag between the cap and the jar with the metal cap on top. That way as it cools, the inside stays clean, but I can easily remove that blocking cap in order to expose the jar to the air when I get to where I want to use it. You then place this somewhere in your yard or in a park or wherever it is that you're trying to capture yeast from. It's generally laid in the evening as the time to do it, and you want to leave it there overnight. Let the air currents carry in the bugs and whatever else yeast that you're looking for. In the next morning, you then bring it home and swap out the lid for an air lock in order to then allow this to ferment. You want to let this go about a month in order to make sure that any potentially dangerous bacteria in there are killed, and this can then be used either to inoculate a new beer or it can be used to purify pure yeast strains, which will be the topic of the next two videos in the Wild East series. So I hope you enjoyed this video, and I'll see you on the next one.
