Primula Cold Brew Travel Bottle with Black Insulating Neoprene Sleeve – Borosilicate Glass and Stainless Steel Mesh Core – Dishwasher Safe – 19 Oz. – Clear

Innovative and Perfect
This is one of the best Amazon purchases I’ve made all year. Perfect for traveling and visiting friends, I’m able to bring my own coffee and take it with me each day instead of being dependent on different coffee styles while I travel. I wish that the filter was a little bit more secure in the bottom of the bottle, there were times that coffee grounds escaped, but otherwise it was a perfect coffee brewing device for a recent girls trip.

Not a good product
I dont know if the one that I got is defective or not, but-First night using it, worked great. Filled the tumbler with some coffee grounds and the bottle with water then left it in the fridge. The next morning my iced coffee was great.Unfortunately, after that, the diffuser just does not seem to work. I’ve tried washing it multiple times and multiple ways, but still since the first night it literally takes 5-7 days for coffee grounds to diffuse all the way. And the bottle leaks. Cheap stuff.

Good, but a bit difficult
This bottle is great at making cold brew, but I feel like there’s a major design flaw. The basket that holds the grounds gets off kilter very easily, which causes the bottom to leak.

So delicious
I have been wanting a cold brew coffee maker, so for Christmas my mother got me this and a pitcher. I followed the directions in the box and let it sit for over twelve hours. I brought it into work with me to have here. We only had the old dark roast from starbucks at the house, so i feel it was a little strong for cold brew. However i added half water and it was delicious! I am so excited about this container!

Item arrived well packed.Works as described, easy to pull apart and clean. I hand wash, don’t trust putting it in dishwasher, as build quality isn’t top of the line (not expecting it for the price of AU$25).Capacity listed as 20oz doesn’t appear to be too accurate, at least usable capacity.Once taking into account the filter and ground coffee I get around 14oz brewed coffee from a full bottle.Tips/Method:1. Only fill coffee filter around half full of coffee grounds.2. Put filter and grounds in first, screw on bottom and then fill with water from top.3. Secure both lids tightly and give the bottle a good shake for around 30 seconds, this gets the water through filter and get the coffee grounds nice and wet. You will see the coffee starting to brew4. Stick in fridge for up to 12 hours. Shaking a few times during the brew process (I’d just do it if going to fridge for something else).5. Give one last shake before serving. I serve with a few ice cubes and a dash of full cream milk.I have been using espresso/fine ground coffee since buying this bottle, course ground coffee suits cold brew better apparently (like French press coffee).Have just ordered a coffee grinder, will update review if it gives different results.Having tried various methods of making cold brew, this bottle has been the simplest and quickest (including cleanup). Definately can recommend.Will prob buy another to ensure endless supply of cold brew in the fridge.

Good
