London has hosted a coffee festival with baristas taking coffee art to a new level.
The biggest trend at this year’s festival is the rise of nitro cold brew coffee. In the new method, the coffee is brewed in cold water overnight and infused with nitrogen at pressure as it is pulled from the pump.
The cold brew trend started life in the US, but has crossed the Atlantic and is now available in coffee shops across Europe.
Also in the festival, is the ‘Latte Art Live’, which is an interactive zone dedicated to the highly popular skill of latte art.
