The cold brew bottle is great, using it has weaned me off of unhealthy syrupy tins of tea, that I used to buy. I enjoy experimenting with different blends but find myself always going back to peach soda tea. I find that the tea is best brewed overnight for a more developed flavour.
After 3 months use I find that the strainer part of the bottle is beginning to look a bit worn, and I am a bit concerned about how long that part will last, I wonder if replacement strainers would be available to order. I also have concerns about how slippy the bottle gets with condensation when refrigerated, I feel the bottle would benefit from a textured finish or a cozy/holder to make it easier to grip.
Overall I love my cold brew bottle and hope it lasts me a long time.
