Also known as Portland Brewing Zig Zag River Lager
Commercial description
Here’s further proof that a drinkable beer can also be an interesting beer. Our Zig Zag River Lager is smooth, mellow and aromatic, with an inviting flavor that strikes a balance between maltiness and hop bitterness. Zig Zag gets its name from the picturesque river that gathers icy snow-melt from the slopes of Mount Hood and carries it westward to the Willamette Valley.
