Just answered my own question with some research. The colder the liquid becomes, the more dense it becomes, the higher the number on your gravity reading. If my initial reading was taken at 115*(1.028), the wort was less dense than it would be at 60* so once the wort cooled it is safe to assume the OG was higher than 1.028. How much I'm not certain. |
There are calculators for this.
http://www.rooftopbrew.net/abv.php - has a temperature field that'll adjust your gravity pretty accurately.
It shows your OG was probably more like 1.035
