Very cool post. I feel like I have seen those around, I will have to take a closer look next summer. That seems like the sort of plant that is so easy to propagate you might want to be careful about where you plant it lest it take over. When making wine or beer the cleaner you want to use and what they are no doubt using is called "sanitizer" that you get from the same place you get your brewing or winemaking equipment, often they are strong acids but it is important to use the right stuff for what you are making so you don't kill your yeast. Don't use bleach or anything like that, I noticed in one of your earlier posts on the topic you spoke of sterilizing equipment but for most fermentations the way to go is to sanitize it using a sanitizer. I have been considering writing a post on ginger beer making whenever I get around to brewing up a batch to take pictures of and that is a similar process although also unique in some ways.
