I had mentioned to you that I thought Eserra really came around from the first few bottles (last summer) to the last time I had it January. Tasting side by side this week, I agree that Eserra was showing better than the most recent Mariedam. Every bottle of Eserra has some benign tartrate crystals, which may put some drinkers off?
That being said, the inaugural vintage of Mariedam remains my favorite.
