A great little gadget to help you on bottling day. Slide the Little Bottler tube into your empty bottle and when it touches the bottom a valve opens and fills your bottle. When the liquid level reaches the top remove the bottle and the correct head space is left. Comes complete with a quality tap and adaptor to fit to your bottling bucket with a flow director at the rear to help prevent sucking up sediment. You can also attach it to syphon tube if you prefer.
