About This Beer

Third iteration of Owen’s English Porter, built on the Gladfield grain recipe he’s returned to across multiple years. The grain bill is consistent: Ale Malt, Munich, Light Crystal, Light Chocolate, Shepherds Delight, and a small proportion of Eclipse Wheat for a smooth finish. Pacific Jade and Taiheke hops — 50g each — split between the 60-minute addition and flameout.

Nottingham yeast fermented at 19°C for the first three days at zero pressure, then raised to 22°C for four days with the spunding valve wound in to capture CO2. Temperature then reduced gradually to 7°C over the final seven days. Kegged, 21.5 litres.

OG 1.055, FG 1.011, ABV 5.76%. A smooth, creamy dark beer — described by Owen as a great winter drink.
