The 180 mash temp is the culprit here, now what to do?
If you like the taste of the fermenting brew then carb and enjoy.
If you don't you could experiment with some amylase http://www.homebrewing.org/Amylase-E...oz_p_1081.html
You could try experimenting with the fart reducing pill Beano which is a type of amylase.
All experimtal though. I have no experience with the stuff aside from the Alpha and Beta Amylase process that occurs naturally in our mash.
I've heard some people say it works and others warn against it because applying the correct amount is difficult to do precisely and have also read it definetly breaks down the long starch chains and allows the yeast to eat them up, sometimes to well resulting in a FG close to 1.000
Just my 2 pennies. Take them with a grain of salt.
