The Orea Big Boy is the large-batch member of the Orea family, sized to brew 500 ml to 1 L in a single go. It keeps the flat bed and high-flow drainage design philosophy of the V3 line but scales it up enough to serve two or three drinkers from one brew.
At this size the Big Boy becomes a notably gentle brewer. The wider bed means water spreads over more coffee without turbulence, and the taller column of liquid at the start of extraction acts like a mild immersion before the drawdown properly kicks in. The result is a big-batch cup that comes out sweeter and rounder than a scaled-up V60 would, with less fuss over pour technique.
A starting recipe: 35 g of coffee to 550 g of water (1:16), medium-coarse grind, water at 94 °C, three or four pours totalling 4:00 to 5:00. Preheat the dripper and the server generously — the thermal mass of coffee plus water at this scale can drop two or three degrees in the first minute of brewing, which shows up as under-extraction if you skip the rinse.
