I'm digging up some old photos to share. I'm partial to ginger beers, and experimented with other flavours available here (in Taiwan). Roselle is our favourite (with lemon, of course), and always carbonated quickly. Turmeric by itself was too much flavour-wise, but half and half with ginger was tasty.
Once I got my hands on some water kefir/tibicos I didn't use ginger bugs anymore (though I have since killed off my tibicos). They are faster and more stable, but rather voracious. I ended up starving them off, though the acid they created probably was a big part of that as well.
