History
Before hops became universal in northern European brewing around the 12th century, ale was bittered and flavoured with a mixture of herbs called gruit. The Ghent city authority held the exclusive right (gruitage) to supply gruit to local brewers, making it a significant civic monopoly. The modern Gruut Stadsbrouwerij, founded in 2009, revives this pre-hop tradition using historical herb combinations. Gruut Inferno is the brewery's strongest and most aromatic beer, with a bitter-herbal character unlike any hop-bittered ale.

Ingredients
- 4kg pale malt (Maris Otter or similar)
- 500g Munich malt
- 5g dried sweet gale (bog myrtle)
- 5g dried juniper berries, crushed

Tip from the editors. Sweet gale is the key herb: without it the gruit character is incomplete. Find it from specialist homebrew shops or online dried herb suppliers.
