if you 'pat' marmite, in the same way that you pat butterthen it turns white.

In February 2007 Marmite produced a limited edition Guinness Marmite of 300,000 250g jars of their yeast extract with 30% Guinness yeast.The Guinness Marmite has a more subtle and smoother taste. Although it is alcohol free, it still retains a noticeable hint of "Guinness" flavour. Its consistency is rather more runny than the normal Marmite and care might be needed when opening the white and black liveried jar.
