It is excellent for cold coffee. I use 70g of medium to coarse ground coffee in 700-730ml of water. It is quite sweet without any acidic taste. I would definitely buy it again. I highly recommend it!!!!

I got it to fit in the refrigerator door. The top part is made of silicone and sits on top of the glass bottle. At first, I thought it would leak or the top part would easily come off, but in the end, there is no issue. Although I had doubts at first, I consider it a better solution than open pitchers. I have made over 30 bottles so far.
