3 Homemade Whole Grain Mustard Recipes
Honestly, we just couldn’t decide which of these whole-grain mustards were our favorite, so we decided to share them all together!
Choose from Lacto-Fermented Beer-Thyme Grainy Mustard, Lacto-Fermented Beer-Caraway Grainy Mustard, and a fun twist with Lacto-Fermented Sun-Dried Tomato and Basil Grainy Mustard.
They all sound amazing, right? You’ll just have to try each of them and let us know which is your favorite.
Why Lacto-Fermentation?
Lacto-fermentation gives this condiment the added benefit of probiotics. And by now, we all know the benefits of fermented food in our diet!
How simple to get them from a condiment!? Almost as easy as these probiotic beverages!
Not only are you getting fermentation from the whey (or non-dairy culture), but you’re also getting probiotics from the apple cider vinegar (as long as you’re using homemade raw apple cider vinegar or a brand with the mother).

What Whole-Grain Mustard Seeds Are Best?
If you prefer more mild mustard, you’ll want to stick with the white or yellow mustard seeds. But if you can handle a little bit of kick, go for the black or brown mustard seeds.
A combination of any or all works perfectly well, too. Find what your taste-buds (and family) like best.
We like to use these recipes as a guideline, but we tend to mix it up depending on what’s in our fridge and pantry at the time. Have fun with it!
How To Make Homemade Mustard (That’s Lacto-Fermented)
These recipes all start out the same, by soaking the seeds overnight in either beer or wine. This helps the seeds soak up that great tangy flavor and really adds to the end result.
What beer or wine should you use? Well, what’s in your fridge? Use whatever you like best!
Then, you mix all the ingredients together in a blender or food processor and whiz away until you reach your perfect mustard consistency.
You can also leave a few of the mustard seeds out to stir in at the end if you like to have some whole-grain in your mustard. This is where your own preference determines how long to blend.
Transfer your mustard to a glass jar and cover. Leave the mustard out at room temperature up to three days.
You can taste it after 24 hours to find your perfect taste, the fermented flavor will intensify the longer it sits at room temperature.
Move the mustard to the fridge and use it in any recipe that calls for mustard!
Lacto-Fermented Beer-Thyme Grainy Mustard Recipe
This recipe combines the flavors of tangy and “hoppy” beer with mustard, thyme, and onion. This makes a fantastic spread on burgers but is also subtle enough to be mixed into recipes that call for grainy or whole-grain mustard.
And it’s as simple as soaking the mustard seeds overnight, mixing in the other ingredients, giving it a good blend, then leaving to ferment for three days.
Though the recipe below says it’s “optional”, we like to add in a teaspoon or so of turmeric to give this mustard a nice golden color. As they say, you eat with your eyes first, and not all homemade mustards turn out a beautiful bright yellow color!
