Are you ever frustrated with your seeming inability to pick out various aromas in wine? It will help if you know the primary smells that are characteristic of each blend or varietal. For example, Cabernet Sauvignon is well known for blackcurrant, Pinot Noir for red cherry, Syrah for black pepper, Merlot for plum, Riesling for green apples, Sauvignon Blanc for grassy, and Chardonnay for apple.
