For Making Almond Milk & Cold Brew, These Versatile Nut Milk Bags Are *So* Perfect

Preparation of nut milk - straining the milk through a milk bag

You likely already know that homemade almond milk (or the nut milk of your choosing!) is on another level compared to store-bought varieties. Getting the best nut milk bag will help you make the best strains, while also opening up your kitchen to other tasty homemade endeavors, like cold brew, yogurt, or juicing. Yep, though it’s called a nut milk bag, it’s an incredibly versatile, low-tech kitchen tool. Before diving into my top picks, there are a few basic factors to think about.


First, consider the material options for the bag, since some may make more sense depending on what you plan to make.

  • Nylon: This durable, synthetic fabric is perfect for cold brew as well as nut milks. It won’t lose its shape and it’s one of the strongest textile materials. Plus, nylon resists mildew. But, nylon can melt if it becomes too hot, so a natural material may be better if you’re considering using a nut milk bag for tea or broth.
  • Cotton: Probably the most popular material for nut milk bags, this natural fabric is soft, affordable, and biodegradable. It’s worth noting, however, that cotton is susceptible to shrinking after washing and is a high-water consumption crop, so you may want to consider a hemp bag if a natural material made from a sustainable and renewable crop is important to you.
  • Hemp: This long-lasting material is stronger and more durable than cotton, and it’s a material that naturally resists pests, so no pesticides are used in the growing of it. Hemp won't stretch out of shape, though it may have a noticeable odor at first.

Size & Shape

Look for nut milk bags with a U-shape or rounded bottom; the curved edges are easier to clean pulp out of than a bag with straight corners. In terms of size, larger options will allow for more versatile use of the nut milk bag. As mentioned above, you can make everything from yogurt to cold brew. Smaller bags are more limited in their utility and work better for brewing tea or infusing a broth with herbs.

With all this in mind, keep reading for the best nut milk bags to add to your kitchen repertoire.

I had been using cheese cloth and had to strain several times and it was hard to clean the cloth between strainings. This hemp milk bag is so closely woven I only strain once and it's done! It strains well the first time, rinses out very easily between batches and then rinses and dries well after I'm done. Do yourself a favor and get one! It's well worth it.”
