"Fall melted in a cup" isn't the most attractive of tag lines, but that's what Starbucks Japan is using to promote its seasonally limited Roasted Nutty Chestnut line of drinks.

It brings to mind images of soggy leaves and pumpkins being boiled into a puddle — luckily, the actual taste of the latte (¥460 for a tall size) and Frappuccino (¥560 for a tall size) versions is much better.

The latter's mix of candy chestnuts and chocolate chips is too sweet, but the former's chestnut sauce adds just the right kick to a regular Starbucks latte.

It might not be autumn in a mug, but it does taste nice on a brisk afternoon.
