Default First Partial Mash problems

Hello all,

I am 2 days out from my first attempt at a partial mash...didn't really go well.

I am making a hoegaarden clone wit with the following recipe :

Hoegaarden:

1.5lb Belgian 2-row Pilsener malt
1.25 lb flaked wheat
8oz Belgian aromatic malt
4oz flaked oats

Mash at 150F for 90 min

Boil:

3.5 lbs DME Pilsner@45 min
1oz Kent Goldings @45 min

.5oz Kent Goldings @13 min
.25oz bitter orange peel @ 13min
3/4tsp crushed corriander seed @ 13min
1/8tsp crushed cumin seed @ 13min
small pinch of grains of paradise @13 min

.5oz Czech Saaz @ 2 min
.5oz bitter orange peel @ 2min
1/2tsp crushed corriander seed @ 2min
1/8tsp crushed cumin seed @ 2min
small pinch of G of P @ 2min


Yeast:

Wyeast 3463 Forbidden Fruit


During the mash I had significant difficulties maintaining temp, and I noticed that my grain bag did not allow enough movement or circulation for the water. The temps were all over the place from 135 to 160.... when I stirred they seemed to even out to about 152 or so. I was using an instant read thermometer on a cable for continuous monitoring.

Sparged at 150 for 10 min and tea bagged for 3 min.

Mixed well then topped up w/filted water

Topped up to 5 gallons.

Measured SG @ 1.034 (YIKES!)

Fermentation started within 6 hours and was very violent and sulfurous.

It has already slowed significantly on day 2 (no visible signs of fermentation, bubbles every 30-40 sec)

I have not taken any additional SG readings, I will do that today and report back.

Is it really possible that my efficiency was this low?? Or is this yeast just a fast starter and slow finisher...

I know the answer at least for now will be see what my SG is...but my guess is I messed up the mash enough that I will have a VERY low ETOH beer...

Any thoughts?

How much water did you use to mash and sparge?

Looking at your technique, it might be the grain bag. You might have had them packed too tight, and you didn't wet all of the grain sufficiently. It could also have been the temp. When you were at when you were below about 145F you probably weren't converting much sugar. If your grains didn't spend at least 60 minutes between 148F and 160F, your conversion rate probably wasn't that good. I wouldn't worry about the fermentation. It sounds like its fine. Your ABV will just be low and the beer might be alittle hoppier than you anticpated. If you want, you could boil 1lb or so of light DME and add it to the primary to raise the gravity.

You probaly didn't mix your top off water well enough, thus the low OG reading. It's really hard to mix it well enough and obtain an accurate SG reading. RDWHAHB

Cumin? Celis mentioned that he only used coriander and orange peel. Making it spicier?

Cumin was in the recipe I had... I added the Grains of Paradise on my own...

I used 1 gallon for the mash and 2.5 gallons for the sparge. Topped with about 2.75 - 3 gallons after the boil.

I think I remember cumin in the recipe I saw too. It was either for Celis of Hoegaarden.

A helpful PM tip is calculating the mash efficiency before starting the boil. Grab a sample of your wort in a tube to cool down. Take the SG once below 100 F and use a brewhouse efficiency calculator to see how you did. After you take the measurement you can dump the sample back into the boil as long as its in there for a least 10 min. Here is the calculator I use. You just have to know how much wort you collected.

Also you might want to try and stabilize your "mash tun" somehow. Was it a pot on the stove? I always wrap my pot in an old towel to help insulate it. Careful you don't burn the towel if you turn the burner on though.

Jedijoel - excellent idea... Not sure why I didn't think of that...

I guess that I could have just mashed longer. Can I mash too long? If I still can't get the efficiency I guess I could have adjusted upwards with the extract.

Definately need a bigger grain bag though.

You know I don't really think so but there is a point where the mash in ineffective. The alpha and beta enzymes used to convert the starch to sugar will eventually cancel each other out so a mash is called "self-limiting." You can read here and the next page if you want.
