I've been away from the GF brewing for a while. But decided to give chestnuts another shot. A friend and I have been wondering about combining light roast chestnuts with GF quick oats. If you've tried chestnut beer before, you probably noticed that it ferments out pretty dry and thin. Our theory is that the oats will give it some body and head retention, while the chestnuts will lend flavor and color. We'll add additional fermentables in the form of BRS and minute rice. Here is what I have for a preliminary recipe:
5 gallon batch
5 lbs Chestnut chips, Light
2 lbs Brown Rice Syrup
1 lb GF Quick Oats
1 lb Minute Rice
1 tbl Amylase
0.5 oz Magnum (60 min)
1 oz Amarillo (5 min)
Whirlfloc
S-04 yeast
If my math is correct, that should give us a SG of 1.040 - 1.050 (depending on how well the chestnuts yield) and ~30 IBUs. I might also add some lemon and/or orange zest at flameout and make a summer beer out of it. I'm a little worried about the getting conversion using the amylase powder. I haven't had a lot of luck with it in the past. I'll probably do a 24 hour mash and have some honey or corn sugar sanding by in case I need to bump up the gravity. Thoughts?
