Nespresso has two lines of capsule-based espresso machines:
For our money, OriginalLine machines are better than VertuoLine machines because their pump produces more authentic espresso, the coffee tends to be hotter, and there's no barcode scanning system meaning you can find less-expensive third-party capsules.
One of Nespresso's best-selling machines, the OriginalLine Inissia is a touch more feature-rich than the uber-compact Essenza Mini with a pair of upgrades:
Capable of brewing shots from 1.35 oz to 3.70 oz, the Inissia has two programmable brew buttons that easily allow you to customize your shot size. Here's how it works:
The machine will remember that brew size for every future brew (until you reset it).
While the Inissia doesn't come with a preset button for Americanos (espresso + hot water, like a regular coffee) like the Essenza Plus does, you can easily use the programmable buttons to set up your own Americano system:
In between pressing both buttons, just eject the capsule.
If you'd like to brew specialty beverages (like cappuccinos and lattes), you could always upgrade to the bundle or purchase the Aeroccino4 milk frother separately for your own home barista setup.
