Robert Parkers interest in wine began in 1967, when he spent a month abroad during his Christmas vacation at the University of Strasbourg in Alsace, France. By 1975, he began to think about writing about wine and commencing his own "independent, consumer's guide," and by 1978, the concept of a wine publication was formulated. The first issue of The Wine Advocate, a complimentary issue, was sent out to mailing lists purchased from several major wine retailers. The initial number of charter subscribers in August, 1978, was less than 600. Twenty-eight years later, The Wine Advocate has over 50,000 subscribers, in over 38 countries. Today, virtually every knowledgeable observer agrees that The Wine Advocate exerts the most significant influence on the serious wine consumer's buying habits and trends not only in America, but in France, England, Switzerland, Japan, Taiwan, Singapore, Russia, Mexico, Brazil, and China.
For more than 25 years, Jose Penin has written about the wines and the wine growers of Spain. In 1990, he published "Guia Penin de los vinos de Espana", which has become the market leader in its field. His totally independent and honest opinions have decided the success or failure of the wines he tastes, and year in year out the sommeliers world-wide check his views and criticisms. His system of marking wines is simple and straight forward and is the 100 point system favoured by Robert Parker. Spanish wines are rated with a system of evaluation which takes account of the purchase price and the quality hence the final equation is a favourable cost-performance ratio.
Following is an explanation of the Parker - Penin’s rating system:
| 95-100: | Exceptional This wine excels among those of a similar type, vintage and region. It is extremely impressive in every sense; full of complexity, both on the nose and the palate. It is elegant and out of the ordinary, far exceeding normal standards. |
| 90 – 94: | Excellent |
| 80 – 89: | Very Good |
| 70 – 79: | Acceptable Although not as distinctive this wine fully reflects the characteristics of the region it is produced from. |
| 60 – 69: | Mediocre An acceptable wine in which slight defect can be detected, but not losing much in the overall effect. |
| 50 – 59: | Not Recommended A harmless but un-enjoyable wine. |
