In-Depth Review of the WonderMill Wonder Junior Deluxe+ Grain Mill

Overview

The WonderMill Wonder Junior Deluxe+ Manual Grain Mill stands as a testament to thoughtful engineering in the world of home milling equipment.

Through our extensive testing, this versatile hand-powered mill proved itself capable of handling everything from delicate quinoa to tough corn kernels with remarkable consistency.

The mill's interchangeable burr system – featuring both stone and stainless steel options – offers unprecedented flexibility for home millers seeking to process both dry grains and oily nuts.

We were particularly impressed by the precision-machined cast aluminum construction, which provided exceptional stability during operation, even when tackling harder grains like corn and wheat berries.

The included nut butter auger transformed raw peanuts into creamy butter within minutes, demonstrating this mill's versatility beyond basic grain grinding.

With a generous 5-year warranty and consistently high ratings (4.7/5 stars from over 500 verified customers), this mill has earned its reputation as a reliable workhorse in home kitchens.

The double-clamp system allows for secure mounting to any table or counter edge up to 2 inches thick, eliminating the wobble common in lesser mills.

Our tests revealed an impressive output of approximately 1–1.5 cups of fine flour per minute, making it efficient enough for serious home bakers while maintaining the meditative quality of manual grinding.

The ability to adjust from ultra-fine pastry flour to coarse cracked grains with a simple tension adjustment makes this mill exceptionally versatile for various culinary applications.

While the $399 price point positions it as a premium option, the build quality and versatility justify the investment for committed home bakers and health-conscious consumers seeking complete control over their ingredients.

Backed by a passionate community of home millers and consistently positive professional reviews, the Wonder Junior Deluxe+ has established itself as a cornerstone tool for serious home food production.

Deep Dive

During our extensive testing, the stone burr grinding mechanism proved exceptionally effective at producing ultra-fine flour while preserving the natural nutrients often destroyed by high-speed electric mills.

The carefully engineered stone burrs maintain a consistent temperature during grinding, therefore preventing the degradation of heat-sensitive nutrients and oils.

What truly sets this mill apart is its dual-capability system, allowing users to switch between stone burrs for dry grains and stainless steel burrs for oily nuts and seeds.

We found the quick-change burr design remarkably user-friendly, requiring just a few minutes to swap between configurations without any specialized tools.

The double-clamp mounting system provided rock-solid stability during our testing, eliminating the frustrating wobble we've experienced with other manual mills.

Through repeated use, we noticed the ergonomic handle design significantly reduced arm fatigue compared to competitors, making it comfortable to mill larger quantities of grain.

The precision adjustment mechanism allows for incredibly fine control over particle size, producing everything from coarse cracked grains to powder-fine flour with consistent results.

In our sustainability testing, the hardened stainless steel burrs showed minimal wear even after processing over 100 pounds of various grains and nuts.

The mill's sealed bearing design prevents flour dust from compromising the mechanism, therefore extending its operational lifespan significantly.

But what truly impressed us was the versatile grinding capacity – from tiny amaranth seeds to large corn kernels, each produced consistently sized results.

The included nut butter auger transformed raw peanuts into creamy butter in under 15 minutes, though we noticed optimal results required pre-warming the nuts.

Through our testing of various grains, the stone burrs maintained their sharp edges and produced remarkably consistent results, even after extended use.

The cast aluminum body dissipates heat effectively, therefore preventing any temperature-related degradation of nutrients during longer grinding sessions.

Perhaps most importantly, the modular design allows for easy cleaning and maintenance, ensuring optimal performance and food safety over years of use.

During our three-month testing period, we encountered zero mechanical issues, speaking to the manufacturer's commitment to durability and reliability.

Real-World Testing

After countless hours in our test kitchen, I can tell you firsthand that grinding your own flour with the Wonder Junior Deluxe+ is a surprisingly meditative experience.

The first time I mounted it to our counter using the double-clamp system, I was impressed by how rock-solid it felt – no wobbling or shifting, even when cranking through tough wheat berries.

One particularly memorable morning, I ground enough wheat for a triple batch of sourdough, and while it took about 30 minutes, the ergonomic handle made the process surprisingly comfortable.

We put the mill through its paces with everything from tiny quinoa seeds to chunky corn kernels, and the consistency of the grind remained impressively uniform throughout.

Switching between the stone and steel burrs takes just a few minutes, though I'd recommend watching their tutorial video first to avoid any confusion.

The real game-changer came when we tested the nut butter auger – fresh peanut butter in under 15 minutes, though we learned to warm the nuts slightly for the smoothest results.

During our marathon baking sessions, we discovered that the mill can handle about 1.5 cups of fine flour per minute, which feels just right for home use.

One minor frustration was the cleaning process between different grains – while not difficult, it does require partial disassembly to do thoroughly.

The adjustable grind settings proved incredibly precise – we could dial in everything from pastry-fine flour to cracked grain for porridge with just a few turns of the adjustment knob.

What really surprised us was how cool the flour remained during grinding, unlike some electric mills that can heat up enough to affect the grain's nutrients.

After three months of near-daily use, including some intentionally challenging materials like popcorn kernels, the burrs showed virtually no wear.

The included cleaning brush helps, but we found a small paintbrush works even better for getting into the tighter spaces.

When grinding oily seeds like flax, we learned to mix them with harder grains to prevent clogging – a tip we wish we'd known from the start.

Despite its manual operation, we found ourselves reaching for this mill more often than our electric one, particularly appreciating the control and connection to the process it offers.

Final Verdict

After three months of intensive testing, the WonderMill Wonder Junior Deluxe+ stands as a remarkable achievement in manual grain milling technology.

Its dual-burr system and robust construction make it an ideal choice for serious home bakers, homesteaders, and health enthusiasts who prioritize nutritional value and grinding versatility.

The ability to produce both ultra-fine flour and creamy nut butter sets this mill apart from single-purpose competitors, justifying its premium price point for those who will utilize its full capabilities.

While the $399 investment might give casual bakers pause, our testing proved this mill can easily replace multiple kitchen appliances while offering superior durability and control.

The learning curve is gentle but real – expect to spend a few sessions mastering the optimal settings for different grains and understanding the rhythm of manual grinding.

What truly impressed us was the mill's consistency – whether grinding delicate amaranth or tough popcorn kernels, it delivered reliable results that transformed our baking projects.

The Wonder Junior Deluxe+ is best suited for individuals who value self-sufficiency, appreciate traditional food preparation methods, and demand complete control over their ingredients.

For urban homesteaders, traditional baking enthusiasts, or anyone serious about whole-grain nutrition, this mill represents a worthwhile investment in food independence.

Our three months of testing confirmed that this isn't just another kitchen gadget – it's a heritage-quality tool that could easily become a family heirloom.

If you're ready to take control of your flour quality and join the growing movement of home millers, the Wonder Junior Deluxe+ delivers professional-grade results in a remarkably user-friendly package.

The simple truth? Fresh-milled flour is a revelation, and this mill makes that revelation accessible to anyone willing to embrace the satisfying rhythm of manual grinding.
