Boasting a deep youthful red color and a very complete nose at this early tasting, the 2020 Barbaresco Riserva Rabaja is brooding with dark aromas of ripe cherry, espresso crema, and leather, balanced with brighter highlights of red flowers, dusty earth, and fresh mint. The palate has a good deal of focus on the palate, with ripe and precise acidity, refined tannins, and a long finish. It is an impressive wine that I would encourage readers to seek out. Drink 2025-2050.

The 2020 Barbaresco Riserva Rabajà is another stellar wine in this range. Dark and explosive, the 2021 possesses notable richness to match its dark, brooding personality. Black cherry, plum, leather, cloves, menthol, licorice and gravel explode onto the palate. The 2020 will require a measure of patience, but it has a ton of potential. Drink 2025-2035.
 
Without a doubt, the 2 most famous Barbaresco producers are Gaja and Produttori del Barbaresco (the producer above). While Gaja is wayyy up there in price, Produttori del Barbaresco always keeps their pricing very affordable. Keynote, the appellation of Barbaresco wouldn't even exist if it wasn't for Produttori del Barbaresco, true story. 
 
Founded in 1958, the priest of the village of Barbaresco, recognizing that the only way small properties could survive was by joining their efforts, gathered together 19 small growers and founded the Produttori del Barbaresco. From its humble beginnings making the first three vintages in the church basement, Produttori del Barbaresco has grown to a 52 member co-operative with 250 acres of Nebbiolo vineyards in the Barbaresco appellation and an annual production of over 500,000 bottles. Its vineyards amount to almost 1/6 of the vineyards of the area. Each member is in full control of their land, growing Nebbiolo grapes with the skill and dedication they have honed over generations.
 
Playing a key role in elevating the quality level of Barbaresco over the years, Produttori del Barbaresco produces a simpler Nebbiolo Langhe, a Barbaresco blend and nine single vineyard wines produced in premier vineyards: Asili, Rabaja, Pora, Montestefano, Ovello, Paje, Montefico, Muncagota and Rio Sordo.
