Low OG

[Pharmbrewer]

So I put my doppel bock together and had quite the discrepency in my OG. I was expecting 1.084 and got 1.064.
11.2 lbs munich
3.2 lbs pilsner
1.6 lbs caramunich
Mashed at 154
Brewhouse eff 68% ish
This was for 6 gallons in the kettle and 4.75 in the fermenter (90 min boil)

I did end up doing more like 7 gal in the kettle. so this could have effected my og somewhat but I wouldnt think to that extent.

Im left thinking that it did not convert. I mashed for an hour however I did not check my conversion . I have never had conversion problems in the past however this is the most munich malt I have ever used in a recipe. My water has low Ca~46 and medium hardness CO3~169 Mag~13. So would the munich have had a harder time converting than my typical mashes?

On a side note I was thinking of adding some dark belgian candi sugar at high krausen to correct for the gavity a little. Any thoughts on this?

Thanks in advance.

I don't think the Munich is the problem. I have a barleywine on tap right now that was 80% Munich and had no conversion problems at all. I think the problem was the extra water in the boil and perhaps too coarse of crush in the mash tun.

Adding the sugar just before high krausen is a good idea. At that point the yeast is still reproducing and therefore can adapt to metabolizing the different type of sugar.

Jamil's Dopplebock has been my nemesis for the last four years. The only time I hit my OG and target volume was when I substituted 8 lbs of LME. Every other time I've been short on gravity, volume, or both. Most likely, you are at or above the maximum capacity of your mash tun.

Just call it an bock instead of a dopplebock and next time add some LME.

What was you water to grain ratio?

I find this to be one of the biggest contributors to my eff.

I actually went with a thinner mash as has been suggested for german beers. I started with 1.5 qts/lbs but then added a little to bring the temp up. Probably ended somewhere around 1.75-2.
