London's gourmet coffee appeals to java-lovers
Marylebone has seen the recent opening of the Sensory Lab - a new cafe that takes a scientific approach to cappuccinos and lattes.
The gourmet house-roasted espresso beans promise to wow discerning visitors staying at luxury London hotels.
Its proprietors will also teach customers how to attempt their exotic filtration methods at their Brewstation, with equipment on hand for people to buy for home use.
In a process the group refers to as "dialling in", every morning lab equipment is used to combine new beans and blends, accounting for the age of the coffee, atmospheric conditions and blend type.
The number of beans in each cup is carefully controlled, including grind size, extraction time and water weight as well as temperature.
All the equipment people need to make their own scientific-java is sold at the central London branch, including the Japanese V60, which features a cup-shaped filter and sustained slow pour drip-feed into a carafe.
Those hopping from one tourist spot to another and looking for coffee on the go have been advised on the best take away spots in the city.
Time Out magazine explains: "Cafes have their place, but sometimes you don't have time to sit in or you just fancy a brew alfresco.
"Coffee carts are convenient and give young baristas a cheap way of making their mark on London's thriving coffee scene."
The publication's top cart is Brewed Boy, located between Rupert Street and Brewer Street, the Aussie-run coffee van serves top quality drinks at around £2.
Lewisham's Exchange Coffee, staffed by barista veterans Lynsey Harley and Neil Le Bihan, features hand-pulled espressos.
