(CNNMoney) - Looking back on my reams of tasting notes and experiences, one thing really stuck out in 2011. Rioja is producing some of the finest wines available at prices that can make a Scotsman blush. Rioja is my region of the year for 2011. The northern Spanish wine region has proven that its wine ages as well as any other, and can age even better than many more famous and costly examples. The ability of a wine to age, to improve in the bottle while morphing into something profound, is one of the core elements that makes wine such an attractive and enthralling subject. Like many wine regions, Rioja went through a rather convulsive final decade of the last century.
