Make your own Kombucha at home and save money!. With prices rising on everything I had to find ways to cut expenses. At the grocery store it cost almost $4 a bottle now for kombucha. Its actually very cheap and easy to make it at home. You just need tea, water, sugar, and starter Scoby that you only have to buy once. I also like that I can experiment and play around the flavors when I make it myself. This is my second time purchasing the scoby from this bender and the quality is always great. Great packaging and fast delivery. It came a lot faster than the estimated date.
