I have just finished my primary on an old fashioned ginger beer that I have been brewing. It's 15l and the bubbles were slowing down, so I filtered it all into another 15l to filter all the ginger pieces, etc. I then topped it up with about 3l of distiller water and added a day of honey to hopefully get it lock started again. Has only been an hour but no sign of any bubbles. I made sure the temperature of distiller water was room temp, so I don't shock the yeast. Any pointers on what I should do now?
