Is Espresso Forte good for lattes and cappuccinos?

Yes. Its full body and cocoa notes come through milk instead of being drowned by it. It is a common pick for milk-based espresso drinks.

How does it compare with Major Dickason's Blend?

Forte is darker and blended specifically for espresso, with more body and less brightness. Major Dickason's is a more all-purpose dark roast that works in drip and French press too.

Do I need an espresso machine to use it?

No. It works in a moka pot, AeroPress or French press, though it is ground for espresso pressure. Any of these methods will show its dark, chocolatey character.

Is it whole bean only?

Yes, this bag is whole bean, so you need a burr grinder for espresso. Pre-ground versions of Peet's espresso blends exist but this one is not among them.

How should I store the 32-ounce bag?

Keep it sealed in a cool, dark place and move it to an airtight container once opened. Whole bean stays at its best for a few weeks after opening.

Is it high in caffeine?

It is a standard caffeinated dark roast, not a high-caffeine blend. Dark roasting removes some mass but not enough to make it a strong caffeine outlier.
