On day 60 my sg is .990, It tastes a little dry and i would like to sweeten it up a little. This is a 3 gallon batch and is very clear, looks to be my best yet. The starting sg was 1.090. What is my aprox. abv. and When I add some sugar mixture to it, will it start to referment??? So how much sugar/h2o mixture do I add. I do not want to make it too sweet but just a little. Thanks la-boy
