A new thread would be fine, but here are my recommendations to replace Burgundy.Ok, I’ll bite. Which Portuguese wine will replace Burgundy? Would prefer if you start a new thread though. TIA.
For Red, the Dao and Barriada. Quinta de Baixo in Barriada produces wonderful fresh, lighter, aromatic reds from biodynamic 70-100+ year old vineyards. This is Niepoort's property. The wines are very akin to premier cru reds. The Lagar de Baixo and especially the Poeirinho labels from 2015 and 2016. Filipa Pato also uses biodynamic old vine Baga. Some well over 100 years old. The Nossa Calcario and Territorio Vivo from 2015 and 2016 are very fine. Filipa's father, Luis Pato produces somewhat richer wines, more akin to grand cru. His single vineyard Bagas are terrific. 2015 was a great vintage for him. His own rooted vinyards, Quinta do Ribeirinho Per Franco and Valadas Per Franco are even more a step up but are now achieving Burgundian prices. In the Dao there's Quinta da Pellada made by Alvaro Castro, one of Portugal's greatest winemakers. Carrosel is his top red. 2011 and 2012 are the latest releases. His other reds are also worth searching out. Also in the Dao is Quinta do Sobral with their Vinha da Neta tinto. 2015, 16, and 17 are all fine.
For white Burgundy, Encruzado from the Dao is the closest thing anywhere having the same texture and weight. It handles barrels just as well. Ribero Santo Carlos Lucas produces a whole range of Encruzado, all excellent. His top wine is Vinha da Neve (the snow vineyard). Both the tinto and branco are great but the branco is all old vine Encruzado. The 2017 and 2018 are fine, but the 17 is just a hair better. Sobral's Vinha da Neta branco is also old vine Encruzado and is great. Alvaro Castro's Quinta da Saes also makes a fine Encruzado. Camino Cruzados has their Titular Encruzado label.
