Saturday and Sunday I had the Bogle Vineyards 2004 Phantom, which I got for about $14 at Trader Joe's, and have been waiting to try for a while.
Saturday night, I popped and poured. I had 2 glasses side-by-side, one in the Schott Zweisel Diva Bordeaux glass, and one in the Waterford Mondavi Syrah glass. This wine is 54% PS, 43% Old Vine Zin, and 3% Old Vine Mourvedre, so I wasn't sure which glass would go best.
However, the experiment didn't really have any result worth reporting. On the first night, it didn't taste great in either glass. The nose was very awkward, both hot and acidic, with some black cherries, blueberries, and cloves. The palate wasn't that much better, with a similar flavor profile, but had nice mouthfeel with soft, chewy, tannins and the fruits had a jammy, extracted, sense to them.
On the 2nd night, the remaining half-bottle was much better integrated and more balanced. As with any PS, I highly recommend a few hours of decanting, as the overnight helped the wine come together and increase the tannins, and I can only surmise that a few more years in the bottle or a while in a decanter would help even more.
