This is a wine making technique that combines different types of wine in order to get the best result. Usually, wines that are blended only require that the grapes be the same type from 40% to 50%. The blending of wines makes the wines more complex and it results in an improved aroma, color, body and finish.
Some wines are made for blending. Some examples are Malbec, Cabernet Sauvignon, Merlot, and many others. The idea of blending is to highlight each wines strengths and complement other types of wine to make the perfect blend.
