Porter Green – stemm + stylish + travelling + ethical + minimalist + motile


Made from excellent non-toxic materials. 100% FDA-approved food-grade silicone.
Porter Green is an all female, family based (three generations). Their stemm products are manufactured in China, using ethical production methods and specialising in silicone products as silicone is such a sustainable material. The manufacturer does not use child or slave labour. The brand's spun bamboo sebss trays are handcrafted by traditional artisans in Vietnam, which assist in supporting the village.
Stemm is made from FDA approved food grade silicone. Silicone is highly durable and more ocean friendly than plastic. Silicone’s durability can be seen in the material’s ability to endure extreme fluctuations in temperatures - from very cold to oven hot - without melting, cracking or otherwise degrading. Porter Green products are packed in biodegradable corn chips, compostable bubble wrap, recycled & acetate free tissue paper and recycled brown paper. The porter green wholesale bulk orders are distributed in recycled cardboard boxes & where practical, local deliveries are done using an electric car and hand delivered.
During COVID Porter Green donated much needed porter green sanitiser to AMBULANCE VICTORIA, THE PRAHRAN MISSION, THE SALVATION ARMY and substantial donations of blankets to the Winter Sleepout and Shelter for the homeless.

What our experts say...

I love the design and stability of stemm – it’s not easy to knock over and lose your drink. A great addition to any picnic, boat or caravan! The product is made from quality materials that are designed to last, which is consistent with my values of quality over quantity.

I like that the cups aren’t fragile. I also like the texture of the cups as they can be packed easily into any bag. I value the family run organisation and the strong relationship with the manufacturers.

I think this is a great idea and product. It could save heaps of plastic wine cups! Love the three generations of women!!! Go team.

Not only are these super cute and cheerful silicone wine glasses ultra-portable being light, flexible and unbreakable, they are super functional too. With a low centre of gravity and weighted base, I’ve found these cups are much less likely to tip over on uneven ground making them perfect for picnics and being outdoors. I also really appreciate the wineglass shape as when I do want to drink wine outside, I much prefer the nod to sophistication rather than having it in a tumbler!
