@keita Funny you should say that — 2005 was one of the legendary years for Bordeaux, alongside 2009 and 2010.
Could just be the producer, of course, combined with personal taste. "Good years" are generally defined by potential for ageing and complexity — the problem is that wines often go into an "adolescent"/difficult/closed stage where they just refuse to give anything in the glass, and it takes another few years for them to open up again. Think caterpillar-cocoon-butterfly.
