'Built-In Milk Frother' denotes whether the coffee maker has a special device for heating and frothing milk, usually by way of a hot steam pipe.

Milk foam is a key ingredient for several Italian espresso-based drinks, such as cappuccinos and macchiatos.

'Timer' indicates whether the coffee maker allows you to pre-fill the machine and set a timer, so that it automatically starts making coffee at a certain point.

This is extremely helpful for first thing in the morning - you can fill the machine before bed, set a timer and wake up to freshly-brewed coffee!

'Water Tank Capacity' is a measurement of how much water the coffee maker can hold at once.

A bigger water capacity means that the coffee maker will need refilling less frequently.

'Adjustable Coffee Strength' indicates whether the you can modify the strength of the coffee produced by the machine, making it stronger or weaker. This is normally done by adding or subtracting 'shots' of espresso from the drink.

Adjustable strength means you can tailor the coffee to personal preferences - not everyone wants their coffee to be rocket fuel!

'Built-In Display' denotes whether the coffee maker has a screen displaying the coffee choices, current coffee brewing, any errors, etc.

A display allows you to quickly see the status of the coffee machine, choose drinks, etc.
