Hi. So... your logo is my 100% favorite ... marketing and branding also happens to be my arena. I like the visual texture of #30. However, my other 2 partners are both males and have engineering backgrounds. They feel it looks like a "truck". Would you be able to look up a "Carboy" (the glass jug that our invention tilts, and see if you can work your magic using a shape more along those lines vs the wine bottle?
Also - perhaps play around with a tilted object?
Good luck :-)
