From our oven to your table — Brew 421 brings the warmth of a real bakery to the heart of Mason City. Artisan breads, house-made pastries, and coffee crafted with care, right here on South Federal Avenue.
Brew 421 started with a simple conviction: Mason City deserves a bakery that treats every loaf, every pastry, and every pour like it matters. We opened our doors on South Federal Avenue to bring that conviction to life — no shortcuts, no compromises.
Every morning, our kitchen is alive. Sourdough rises. Croissants fold into buttery layers. Coffee is pulled with attention. We source locally whenever we can, and we bake in small batches so what reaches your plate is always at its best.
Long-fermented crusty loaf with a soft, open crumb. Baked fresh every morning.
Hand-laminated French-style croissants with layers of flaky, golden pastry.
Single-origin espresso pulled to order. Lattes, cappuccinos, and seasonal specials.
Soft, pillowy rolls swirled with cinnamon and topped with cream cheese glaze.
Whether it's a office meeting, a family celebration, or a community event — we'll craft a custom spread of fresh breads, pastries, and coffee that makes your occasion feel special. Let us handle the food so you can enjoy the moment.

Nothing makes us prouder than hearing from the people who stop by our counter every week.
The sourdough here is hands-down the best in town. My family drives from out of town just to grab a loaf on our way home. The crust, the tang, the way it keeps — you can tell they truly care about the craft.
I stop by every morning before work for an espresso and a croissant. It's become my favorite part of the day. The staff remembers my order and always makes me feel welcome. This place is a gem.
We ordered a pastry platter for our office event and everyone was asking where we got it. Brew 421 made it so easy — great selection, delivered right on time. We'll definitely be back for our next gathering.
We're right on South Federal Avenue — easy to find, impossible to forget.
