Review: Soyajoy G4 Soy Milk Maker

soyaJoy G4 with stainless text

Recently, Soyajoy came out with a replacement for their top-selling soy milk maker. For 2013, Soyajoy now has the G4 soy milk maker, a replacement for their older, G3 model.

The product description (according to the manufacturer) is that the SoyaJoy G4 is the next model to the 5-star rated SoyaJoy G3. The G4 retains all features of the G3. Key improvements are the G4's all stainless construction of the cooking and grinding chamber, increased capacity, and the filter-less bottom heating with Perfect Grind Technology (TM). Not all soy milk makers are created the same. The G4 uses premium components such as the low noise DC motor, solid state power control, and #304 stainless steel. The microprocessor and the  sensors continuously monitor and control the grinding and heating process to
make perfect milks, soups, or porridges.

The changes between this year's model and the older model:

  • An Increased capacity (now 1.7 liters) and bottom heating technology
  • Important! - It is now made of all stainless steel for the grinding and cooking chamber. No food color stains on plastic or concerns of plastic leaching into food
  • Five automatic, one-button functions for fully cooked milk, soup, and raw vegan milk from beans, grains, and nuts.
  • 4th generation filter-less design for easy use and cleaning with Perfect Grind Technology (TM) for high milk yield.
  • High tech design complete with advanced temperature and water level sensors, and solid-state power controls for superior performance and durability

Here's a side-by-side comparison between the G4 and its predecessor, the Soyajoy G3 soy milk maker


Here is a reviewer on Amazon's comments: Soyajoy G4 makes great tasting soy milk and requires very minimal effort from its user. That doesn't mean no work, but it's far easier to make soy milk with this product than using traditional kitchen tools like pots and blenders.

I used to buy soy milk from a grocery store, and there are several things I had to learn (or am still learning) when I switched to making soy milk at home:

1.Soy beans need to be soaked in water overnight before cooking (though Soyajoy G4 does have an option for both soaked and dry beans, soaked beans would yield better result according to the manual). So if you wake up in the morning and realize that you don't have enough soy milk left for your breakfast cereal, oops, too late.

2.Making soy milk yields quite a lot of okara (pulpy left over from milking process). Okara is nutritious and beneficial for one's health, but incorporating okara into my daily diet isn't so intuitive and I'm still learning how to make good use of this byproduct. Thankfully there are many blogs and websites that have recipes using okara as main ingredient.

3.The device needs to be washed right after operation. If the device is left unwashed for a while, soy residue would start to dry and stick to the stainless steel surface. This happens very quickly because the working part of this device remains pretty hot after operation. When this happens, I find it easier to run the device with hot water and a few drops of detergent before cleaning with sponge.

Overall I am satisfied with Soyajoy G4. It does require a bit more work than picking up cartons of soy milk from a store, but the taste of homemade soy milk is worth a little extra work in my opinion.

Besides making soy milk, it is also great for almond milk. Jane used to buy almond milk from our local grocer's all the time, but now she always makes almond milk at home. It's easy and it's incredibly inexpensive.





  1. Hi I just purchased a SOYAJOY G4 and i was wondering whether it could blend fruits and vegetables and i could use it as a juicer too?
    Thank you 😀

  2. Hi Malorie

    I do not recommend to use it as juicer and it did a poor job, but other than that, it is great for soy milk or mixed beans drink. Follow instruction is extremely important. Quality is good and easy to clean too.

  3. Thanks Lane! One more thing though. I tried using my new SOYAJOYG4.I put in a cup of soaked beans and water between the two marks and pressed soaked beans but it keeps on beeping and does not start.Hope you can help me out because am waiting to make fresh and delicious soy milk 🙂 Thanks

  4. Hi, Lane.
    I’m having the same trouble as Malorie. I put water between the two marks and soaked almond beans. Pressed the raw juice button, it beeps twice, and then keeps on beeping but never start working. Hope you can help. Thanks!!!
