Michael, this post made me sad. I actually am a big fan of South African wines, and a big fan of Mulderbosch's Sauvignon Blanc (true story: back when Muldie SB was allocated, friends who knew I loved it brought a case to my hospital room to give me a reason to live--apparently it worked
). But this rose? I've had it in at least two prior vintages and my impressions of both matched yours of this. I didn't like their chenin either. But their Sauvignon Blanc, if you like the grape, is bliss. Try that, or another South African wine. Don't judge them all by this.
