Grow Forward Premium Wheat Straw Cups: The Eco-Friendly Tumbler That Actually Holds Up

Most “eco-friendly” cups are either flimsy bamboo that splinters or overpriced stainless steel that leaves your drink tasting metallic. The Grow Forward wheat straw cups try something different — and at $15.99 for a two-pack, they’re worth a serious look.

What You Actually Get

The bundle includes a 13 oz and a 20 oz cup, each with a bamboo lid, a bamboo straw, and a silicone cleaning brush. The cups are molded from wheat straw fiber — a byproduct of wheat harvesting that would otherwise be burned — mixed with food-safe polypropylene. The result looks like matte ceramic but weighs about 40% less than glass.

As shown in the product image, the wheat straw texture gives each cup a unique speckled pattern. No two cups are identical, which is part of the charm. The 13 oz holds a standard coffee order; the 20 oz fits a large iced latte or a solid water refill.

Real-World Performance

Here’s where these cups surprised me. The double-wall construction isn’t just marketing — it genuinely insulates. I filled the 20 oz with iced coffee at 9 AM, and ice was still present at 1 PM. The exterior stayed dry, no condensation rings on my desk. The bamboo lid seals with a silicone gasket that actually works; I tossed the 13 oz in my work bag sideways and didn’t lose a drop.

The drinking experience is notably better than plastic. The wheat straw composite has a slight texture that feels closer to stoneware than disposable. It’s also BPA-free and doesn’t retain flavors — a strong cup of black tea rinsed out clean with no lingering aroma.

What Buyers Keep Praising

The 4.8-star average across 240 ratings isn’t inflated. Buyers consistently highlight the same wins:

• Durability: “Dropped mine on tile floor — it bounced, didn’t break. My ceramic mug would’ve been in pieces.”
• Aesthetics: “Looks far more expensive than it is. Guests always ask where I got them.”
• Eco-credibility: “I’ve replaced 30+ disposable cups a week with these. The wheat straw material feels legitimately premium.”

Where It Falls Short

Car cup holders are a gamble. The 20 oz has a wide base that won’t fit most standard vehicle cup holders. Measure your holder before ordering if that matters to you.

Hand-wash only. The bamboo lid will crack or warp in the dishwasher. The cups themselves can technically go on the top rack, but the lids require gentle treatment. If you’re a “everything goes in the dishwasher” person, this will annoy you.

No insulation for hot drinks. The double-wall keeps cold drinks cold, but hot coffee loses heat faster than a proper thermos. These are cold-drink cups first.

Who Should Buy These

Buy them if you’re:

• An office worker tired of disposable cup waste
• A parent looking for shatterproof cups for kids (the 13 oz is perfect for small hands)
• Anyone who wants a conversation-starter that’s actually functional

Skip them if you’re:

• A hot-coffee-all-day drinker — get a vacuum-insulated steel tumbler
• Someone who refuses to hand-wash anything
• A commuter with a tight cup holder in your car

FAQ

Q: Are these cups truly biodegradable? A: The wheat straw fiber is renewable, but the cups contain food-safe polypropylene for structural integrity. They’re recyclable in most programs but not backyard-compostable. That’s an honest limitation.

Q: How many cups come in the box? A: Two cups (13 oz and 20 oz), two bamboo lids, two bamboo straws, and two cleaning brushes. The brush is small but does the job on the straws.

Q: Can these hold carbonated drinks? A: Yes, the seal is tight enough to hold carbonation for a few hours. Just don’t shake them — the pressure could pop the lid.

The Verdict

Buy it if you want an attractive, durable, eco-conscious cup that handles daily cold-drink use without feeling cheap. Skip it if you need microwave-safe, dishwasher-safe convenience or a car-cup-holder fit.

At $15.99 for a two-pack with lids and straws, the Grow Forward wheat straw cups deliver solid value. They’re not perfect — the hand-wash requirement and car fit are real tradeoffs — but for the price, quality, and environmental upside, this is a genuinely smart buy. 4.6/5 stars.
