Can you tell what a wine will taste like from the shape of the bottle?

The shape of the bottle comes from regional traditions rather than being designed to change the taste of the wine.

The Bordeaux bottle has high shoulders and is often used for Cabernet Sauvignon and Merlot.

The Burgundy bottle is more rounded, with sloping shoulders. It is commonly used for Pinot Noir and Chardonnay.

The Rhine bottle is tall and narrow and is often associated with Riesling.

So, the shape of the bottle can give you a clue about the style of the wine, but it does not guarantee its quality or taste.
