120 minute boil = Low TG

Shaggyt said:

So I have noticed that when brewing a batch of beer that boils for 120min, the terminal gravity tends to be extremely low. I normally boil 90min with great results but my sparge process on my latest batch resulted in more wort than expected, so I decided to boil longer. No signs of infection either.

Has anyone else had this issue with 120min boils?

I assume that the longer boil must breakdown complex sugars.

what was your preboil and post boil gravity./QUOTE]

Preboil was 1.053, post 1.065...chimay rouge clone loosely based on the recipe found on brew365. FG is 1.004...hydrometer is fine, recipe below:

22# Golden Promise
1# Caramunich
1/2# Aromatic
2oz Chocolate
1# candi sugar

11 gal yield

Yeast - WLP500

Tastes good though alcohol is hot! Mashed at 151 plus the candi sugar would make really fermentable wort...but that fermentable?

After reviewing my brew notebook, the other 120min boils have been very low FG as well...thus the post to see if anyone else has experienced the same.
