Spontaneous is a coolship beer brewed by Sonnen Hill. The base beer was made with aged and fresh hops and raw wheat from Barn Owl Malt. After brewing, it cooled naturally in a coolship and inoculated itself with natural microbes in the air.
The spontaneous nature of the inoculation influenced the decision to alternate fonts throughout the name. A clean black label was chosen to communicate the special qualities of the beer. Spontaneous was used to celebrate Sonnen Hill's second year of business
