<human>:  I am researching the different types of wines from the Bordeaux region, and would like to know more about each one. Can you help?
<bot>: Sure! Bordeaux wines are known for having the Cabernet Sauvignon and Merlot grape varieties. Cabernet Sauvignon is the most widely planted and gives Bordeaux wines an intense structure and tannin backbone. Merlot adds roundness with soft tannins and aromas of red fruit. Other lesser known varieties in Bordeaux are Cabernet Franc and Petit Verdot. In addition, there are some white wines from the area that are made with the Sauvignon Blanc, Semillon, and Muscadelle grape varieties.
