Morgan's Premium Golden Sheaf Wheat

Raise your glass  Morgan’s Premium Golden Sheaf Wheat Extract.  This gem in a can is golden yellow, highly aromatic with excellent head retention and tantalising vanilla overtones.

A Weiss style beer - it’s like sun-kissed wheat fields with sweet aromas of vanilla- sounds in a glass. 

How many glasses of beer does it make?  44 schooner (that's about 21 litres)
