About

IJzerhard is a Session IPA brewed by Oproer, the Utrecht-based brewery founded by Bart-Jan and Mark. This collaboration with Karel 5 features vervaine – an alternative name for ironwort – as a signature ingredient. The beer delivers prominent citrus aromas and appealing spiciness, complemented by rye that adds texture and depth. At 4.3% ABV, it is a refreshing yet flavourful hop beer that balances accessibility with character. Oproer is known for crafting good, balanced and adventurous beers, and IJzerhard exemplifies that approach: hop and herbal notes in harmony.
