I make my own kombucha with Organic Black Tea, Organic Green Tea, Organic Raw Sugar and Distilled Water. I am offering my extra SCOBYs to you. These SCOBYs all look different from each other. They are not growing in a lab! They are growing in a home kitchen. :-) Color may vary. Sometimes they are "perfectly shaped" and sometimes they are lumpy, bumpy or have a hole in the middle! These SCOBYs come straight out of my brewing jars. SCOBY size is approximately 4 - 5+ inches in diameter. If I feel like a SCOBY is a bit small for brewing 1 gallon I will add a second SCOBY. :-) Often times dark stringers of yeast will also grow in a jar of kombucha. Although some may tell you that is healthy, that is not what I have been taught. I believe it is normal, much as a few little weeds in a vegetable garden are also normal. We pull the weeds out of our vegetable garden before they have a chance to get big! This is also my policy with yeast in the kombucha. I try to remove the little pieces and never let them get big! I will send you a size SCOBY which is easily sufficient for making a gallon of kombucha, along with 1 cup starter kombucha and basic instructions. You have the option of ordering with or without a cotton cloth cover for your brewing jar. Or you may also add 2 cotton covers to your order. Some folks like to cover their brewing jar with a coffee filter. Some use a cotton cloth. I personally like a cotton cloth which looks homey. It can be washed when needed and lasts indefinitely. The covers I am offering are 100% cotton. If you are purchasing one cover along with your SCOBY please send me a message telling me which color/print you desire. If you do not send me a message I will send my choice! If purchasing a set of 2 covers and you wish for 2 colors/prints rather than both covers being the same feel free to send me a message and ask if I can do so for you! Covers are approximately 11 inches square. I ship your SCOBY in a glass jar. Comes from a smoke free, pet free home. If you would like to order more than one item from this listing I suggest you place all items in your cart and "request a total" from me. I can probably give you a better shipping rate than what would automatically give you! I generally check emails at least 2 times a day (except not on Sunday), so I generally will get back with you promptly! Please feel free to contact me with any questions or any issues with placing your order! I am here to assist you! :)
