Re an above post, in Dallas the Tom Thumb stores are owned and operated by Safeway, although they retain a more upscale image, as when they were previously owned by Randall's.
In Houston, Randall's operated under that name. One such store was mentioned in a mystery novel by the superb author David Lindsey.
I once wrote an article on coffee for the food pages of a major newspaper. It was fun to research, and I tried many coffees from a variety of countries.
Overall, I prefer a top Columbian Supremo blend. In Dallas, the Central Mkt. gourmet grocers have an excellent selection of coffee from a number of countries. They also stock many of Twining's superior teas. As an aside, Robert Twining founded his company in 1706 and they remain perhaps the leading shipper of superior tea. Twining's holds the Royal Warrant as supplier of tea to Queen Elizabeth II.
I favor a drip style coffee maker.
Among instant coffees, I think that Taster's Choice has a slight edge over my next most favorite, Nescafe Clasico.
BTW, my first exposure to coffee on an intellectual level came when someone passed out brochures from, I think, the Pan-American Coffee Institute (Bureau?) . I was in elementary school, but remember that the brochure claimed that some Latin American men drink as many as 40 cups a day! They must be as nervous as a mouse that has just realized that a black mamba has him in its sights!
