I did a not-so-blind-test comparion of these today. With some surprising results.
Ampamakia: Similar smell, but slightly more nut in 2004. 2004 is somewhat lighter brown, 2003 more reddish.
2004: Distinct walnut taste, some liquor, cherries. More punching red fruit acidic than 2003.
2003: Less nut, otherwise similar, but less cherry and generally not so punching taste.
2004: Very chocolaty taste, some cherry but otherwise little fruit, some liquorice in the aftertaste. Distinct walnut taste.
2003: More acidic than 2004, some red fruit, somewhat darker and with a hint of smoke, not nuts, just a hint of liquorice.
Verdict: 2004 wins hands down on both. Strange result, because the first time I tried the 2004s I thought exactly the opposite. Should mention, though, that the 2003 bars were 2 months overdue on consumption date, which may have deteriorated taste.
