Breakthrough Kefir hacks

I just started making kefir again.  I think it took me a while to get over the loss of the culture I had going for years, and I needed time to be ready for a new culture in my life.  This new culture is exceedingly vigorous, like it's got something to prove.Throughout all those years rinsing the grains with my fingers, it never occurred to me there might be a better way.I finally had an aha moment, though.  I sewed a little bag out of nylon screen (like, bug screen), that fits into a mason mouth.  Simple, open on top.Then the grains get rinsed off while they're in the bag! You don't have to chase after them.   Genius!I can't imagine why I didn't think of something of the sort ages ago.
