With both experience in the wine industry, as well as Bachelor's in English, I am certain that I could produce compelling and well-written blog posts for your business.
Two years ago, I wrote blog posts and varietal descriptions for a newly launched specialty wine club in California, requiring a blend of technical and friendly/marketable language for the intended audience.
I have also written hundreds of pages in educational material on wine for my past three employers, including an introduction on wine, including aspects of viticulture, viniculture, history and how to taste and select wines.
These and other experiences have taught me how to best tailor language to audiences by being both educational and fun to read, attributes I believe make for the best blog posts about wine (and many other subjects, too).
