Another great red choice is this Renzo Seghesio Barolo Pajana Gran Riserva 1998. It's just beginning to open up 15 years later and it is beautiful. I have the great fortune of pouring this tomorrow night during a company off-site event.
First, the biggest difference is place, the second being grape. Barolo hails from Piemonte and is made from the Nebbiolo grape. Brunello di Montalcino is a native of Toscana and made from Sangiovese. These two have often been referred to as "king and queen" of Italian wines. With Barolo being the more masculine, dark, king that needs a lot of aging and Brunello, a derivative of Bruno is the queen with a smooth and more feminine character while holding onto many masculine characteristics. Renzo Seghesio Barolo Pajana Gran Riserva 1998 is one of our favorites right now, IWM is the only retailer who has it!
