I am brewing a Robust Porter that had an OG of 1.075 and I moved it to Secondary after 3 days at 1.028. The yeast used was Danstar Windsor and so the calculation for attenuation was about right. I have been told by a few brewers that this is too high a gravity and that the ale will seem syrupy. It has been in the secondary about 5 to 6 days and has moved no further. Should I add additional yeast to move the gravity down to a level closer to 1.020? I was thinking of using Safeale 05 since I have some around.
The brew still looks pretty thick and so I assume there may be more sugars to be feasted upon. The secondary is a 5 gal. carboy, so there is not a lot of room for activity other than a gentle munching on the residual sugars.
Advice? It sure tastes good, so I don’t want to make a mistake.
