I recently bought some liquid rennet that comes with a large twist cap opening. I make 8L batches so I use very small amounts. It's a bit of a pain to pour such small amounts from a large opening. I thought about a syringe, but I'm a little hesitant as I wouldn't want to accidentally contaminate the whole bottle.
Anyone have a solution for this? Ideally, I'd buy my own empty bottles with an appropriate cap, but can't seem to find anything. Mabe I'm looking in the wrong direction?
