Jack B. Keller, Jr. lived in Pleasanton, Texas, a half-hour south of San Antonio. Winemaking was his passion, and for decades he made wine from just about anything fermentable and nontoxic. Jack developed scores of recipes and tended to gravitate to the exotic or unusual, having once won first place with jalapeno wine, second place with sand burr wine, and third with Bermuda grass clippings wine. After settling permanently in Texas, Jack was six times elected President of the San Antonio Regional Wine Guild, became a certified home wine judge, periodic contributor to WineMaker Magazine, and creator and author of The Winemaking Home Page-the largest home winemaking website in the world. Jack's WineBlog was the first winemaking blog on the internet. Jack married his high school sweetheart, Donna, and was an avid fly fisherman. He was mentor to thousands of amateur winemakers. Daniel Pambianchi is a well-known winemaking author, lecturer, consultant, and seasoned winemaker. He owned and operated a small commercial winery in Niagara Wine Country in Ontario, Canada. His bestselling book, Techniques in Home Winemaking, has become the go-to reference textbook by advanced amateurs and small-winery operators alike. His area of expertise is wine chemistry, in which he performs extensive studies in his wine analysis lab. He is a member of the American Society for Enology and Viticulture, the Australian Society of Viticulture and Oenology, and the American Wine Society. Daniel lives in Montreal, Quebec (Canada).
