That's an interesting suggestion. I know my wife has a ton of decorative marbles around the house. I don't think I will do it but it could be interesting seeing how upset she gets for me putting her marbles in my carboys. :db
When I rack from my primary to my carboy if I have too much headspace what is best to top off the carboy? I have heard that water will just weaken the alcohol content so I am not sure what else to use. Suggestions???
