Lopez de Heredia is one of the most venerable producers in Spain.  Their wines are made only with estate bottled fruit from their prized vineyards and are released at least 5-10 years after harvest.  Luiz Gutierrez of Robert Parker's Wine Advocate rated this wine 93+ points.  “The 2013 Viña Bosconia Reserva [was] matured in barrels for five years and was bottled unfiltered but fined with egg whites.  It's expressive, elegant and subtle, clean and complex, with polished tannins and very good acidity.  70,000 bottles produced.  It was bottled in May 2021.”  (Feb. 29, 2024).
