Small Cotton Muslin Bags
Product Review (submitted on March 23, 2014):
These little bags are just what I needed for making water kefir. I use them to keep my fruit separate from the kefir grains. The bags are just the right size for getting through the mouth of my gallon brewing jugs, and they hold just the right amount of fruit (figs, raisins, lemon wedges). They are easy to clean; I just turn them inside out and rinse them under hot water after every use (they air dry in a few hours). An added bonus that the description fails to mention is that you get 3 bags each order, which is well worth it.
Response from CFH: Glad you like them! And the description now does state there are 3 bags in the set.
