Ellie's Best Pro Quality Nut Milk Bag

The Workhorse Strainer That Changed My Fermentation Game

This 12"x12" (30cm x 30cm) nylon mesh bag isn't just for nut milk — it's become my go-to strainer for everything from kefir to kombucha SCOBYs. After five years of daily use (yes, the same bag), it's still going strong, which explains why it has over 16,000 reviews and juice bars swear by it.

Built for Real Kitchen Use

  • Commercial-grade nylon mesh — 90-micron weave catches pulp while allowing liquid through
  • Triple-stitched seams — handles aggressive squeezing without tearing
  • Rounded corners design — no more trapped pulp in square corners
  • 12"x12" size (30cm x 30cm) — large enough for big batches, small enough to handle easily
  • Nylon drawstring closure — keeps contents secure during straining

Beyond Nut Milk: A Fermenter's Swiss Army Knife

Sure, it makes silky almond milk in minutes. But this bag truly shines in fermentation applications. Strain yogurt into Greek-style thickness overnight. Filter kombucha without losing carbonation. Squeeze excess whey from cheese curds. Even use it as a sprouting bag for grains. The nylon construction means it dries quickly (no mold issues like cotton cheesecloth) and cleans easily under running water. One reviewer used theirs over 50 times — mine's well past 200 uses. At this price, it pays for itself in saved cheesecloth within weeks.

🥛 If you only buy one straining tool for your fermentation kitchen, make it this one — versatile enough to replace multiple specialized tools.

A Colander You’ll Actually Brag About

You wouldn’t think a colander would be something you grow attached to. But here we are.

This one’s sturdy without being clunky, polished without being flashy. The walls are basically a constellation of tiny holes, which means water rushes out in seconds — and your pasta, berries, or curds stay exactly where they should.

I bought this thinking, “It’s just a colander.”
I’ve since used it to rinse herbs, drain yogurt, catch tomato seeds, and even rest steaming veggies. It’s one of those pieces that quietly proves its worth, over and over.


Why I Recommend It to Friends (and Strangers)

  • 5-quart (4.7L) capacity — plenty for big batches but not awkward to store
  • Precision-punched holes — no mushy buildup or slow drains
  • 18/8 stainless steel — solid, smooth, and no weird smells ever
  • Raised base — keeps food lifted above standing water
  • Dishwasher safe — because life’s too short to hand-wash steel rings

Real Talk

If you’ve ever watched quinoa or angel hair pasta slip through the cracks of a lesser colander, you’ll appreciate the difference here.
This one just works — fast, clean, dependable.


🌀 Turns out, a great colander kind of makes you feel like you’ve got your act together.

The Over-the-Sink Hero for Mess-Free Rinsing

When I’ve got a big load of berries, greens, or pasta to rinse — this is the colander I reach for.
It’s not my everyday strainer, but for over-the-sink operations, it's absolutely brilliant.

The fine mesh is tight enough to keep tiny grains from slipping through, and the expandable rubber-grip arms mean it fits snugly over just about any sink. Plus, it gives you back your counter space — which, let’s be honest, is always at a premium.


Why I Keep It Handy

  • Expands from 14" to 21" (35.5–53 cm) — fits sinks big and small
  • 6-quart capacity (5.7 liters) — roomy enough for a serious rinse session
  • Fine mesh stainless steel — no more losing quinoa to the drain
  • Rubberized grips — stays put without scratching your sink
  • Resting feet — doubles as a countertop basket for holding produce
  • Dishwasher safe — cleans up easy, dries fast, resists rust

What I Use It For

  • Rinsing leafy greens without getting soaked
  • Letting washed produce air dry while I cook
  • Draining pasta when I want to keep my counters dry
  • Sifting flour or catching straggler grains when pouring

It's not flashy — just super functional. One of those tools that quietly earns its spot in your kitchen routine.
Especially when your sink is your second prep station.
