the sourdough jar was delivered VERY well packed. opening it, i found an extremely well designed product. its' maker obviously gave careful thought to it's design. the jar is glass, of a generous size, so there is no worry about leaching chemicals into your starter, it is round; so easy to clean, a volume scale and the tare weight of the jar are printed on the side so you can easily accurately add water & flour, there is a "last fed on:" vertical line along with an elastisized band with days & times printed on it for keeping track of feedings, the band can also be set at the level the starter was at when last fed, so you can easily see it's rise. there is a strip thermometer that sticks to the jar. there is a screw on lid for when it is in the fridge, & a porous elastisized cloth top for when it's on the counter. & the included spatula has a wooden handle.
the only thing this sourdough jar does not include is the starter culture... but... they do have recipe's on their website.
the knead ace sourdough starter jar is the best i have seen, i highly recommend it.
I actually bought one of these, used it a while and bought a second one. I really like the “time band” that comes with it. I do wish the tip of the spatula was a little stiffer but I may buy a third one so you know I like this product.
I'm a first-time sourdough baker and when I saw a pro on IG using their KneadAce jar, I had to have it! It's perfect for recording when I fed my starter last and seeing how much it's grown from day-to-day! The additional thin spatula, thermometer sticker, and linen cap is super helpful! Everything shipped fast too!
