Love it or hate it...Marmite made from yeast from 4 different breweries, is about to reveal its "Big Brother" or the "Mother" of all Marmites

An extra strong version of the spread is due to go on sale this month and is a result of a secret recipe matured 28 days (4 times longer than the regular Marmite)

With the extra time maturing, XO allows the already full flavored spread to intensify, creating a spread so strong and full bodied, that it can only be appreciated by the most devoted fans.

This new recipe was developed with the help of a group of Marmite fanatics calling themselves the 'Marmararti'
