Strekov's Fred wine blends from Slovakia consist of Alibernet and Dunaj grapes. But what is interesting in this one is that the series consists of several bottles in numeric sequence (e.g. Fred #2, Fred #3, etc.) where, as far as we can tell at least, the only discernable difference is the blend percentage of the two grapes (what they are, well, we can't tell).
From there, the wines are produced with minimal intervention at all and the result is an incredibly juicy, fruit-forward wine.
