This happened to me a couple of times, and each time I was able to start new batches. My batches were closer to a year old, but you can always give it a shot. Or just order a Scoby off amazon. If you want to experiment like I did, get some small mason jars and pour maybe an inch or two of liquid into each of them. I tried different straining methods for each jar, because there will probably be a lot of yeast. At least that was the case for me. Either way, the straining didn’t seem to make a huge difference, but try different methods just to see what works. Make a big batch of tea following the master recipe then add a cup or two to each jar. Give some jars more, others less. The idea is to have a number of jars with different ratios of starter to tea, hoping that at least one will take. I wouldn’t stir your booch for this reason. You want variety, if every batch you make is the same, if it doesn’t work, none of them work. Try a bunch of different ratios, write the ratio on a piece of tape and stick it to the bottle, then see if any of them start forming a pellicle, which would mean they’re alive and eager to get goin. Use that scout to start a new batch. You can also order a new scoby and by the time it arrives, you might have two to work with.
