I bought a couple to try in comparison to the Ulithorne Frux Frugis, flight of 6 in my Monday tasting group.
Ulithorne Frux Frugis McLaren Vale Shiraz 14.5% $45.00 - natural cork, nice oak, but the fruit is a little muted and it's quite astringent, didn't impress. Group #5.
The Iconic Big Boy McLaren Vale Shiraz 14.5% $18.00 hmm, the similarity stops at this being as astringent or more than the FF, with some herbal notes, tinned asparagus/corn, not pleasant. Group universal vote last. It's no longer listed, but I might query them about it anyway.
Didn't follow it up and haven't opened the second bottle.
