If there's one thing I know, it's that a lot of knowledge and truth comes out after enough liquor. Whether that knowledge is useful however, is a different story. To be perfectly fair, I really have no idea what's in these bottles, but given that there were a bunch of sake breweries in the area, I'm going to go with my gut guess of sake. Also, feel free to call it knowledge extractors.
I processed this image with Nik Analog Efex Pro to get this look. I really think the Nik Software products are top notch, and I can understand why Google bought a company that puts out some quality products. I'm not planning on doing a review of their software - if you're looking for that there's a ton of other reviews out there, but I can say I do love their software.
