A swift pint

The time taken to brew beer has been cut from six days to just one by
researchers at VTT, Finland’s national research lab. Ilkka Virkajärvi has
achieved this record-breaking brew by coating wood chips with concentrated yeast
and dropping them into the brewing vat where the yeast works efficiently,
converting sugar into alcohol. A pilot plant is already brewing up to 1200
litres a day.
