I like the direction of #4 and #5. Has a good vintage feel, but modern enough to not feel too "old-timey." It does feel a little "light" to me. Wondering what something more "substantial" in this vein would look like?
While a different direction, I also like #3. I'm not 100% sure of the font for "Southern," but I'm intrigued by the "Whey" portion. It kind of has a beer label feel, which is cool since I will be selling craft beer and small production wines as well.
#6 feels a little "soft" for me...but I'm starting to notice I'm attracted to more angular shapes, so maybe that's why. The "Southern" is ok (think it's the same font as #4 and #5), but not crazy about the font or treatment for "Whey."
