Notes

This is a Samuel Adams Chocolate Bock Clone I came up with. Only difference is I added a little bit of the de-husked carafa 1 malt to give it a more chocolatey color and taste with out the astringency, and I used a slightly less toasted caramel than they did to balance it out (45L instead of 60L). I know it seems like a realy long boil off (at least 4 hours of boil time to get down to 5 gallons), but that's the recomended amount of water to use
(1-1/4 qt per lb of grain for mash and 2 qt per lb for sparge).

How did it turn out? I'm new to brewing myself. The recipe looked good, but I was thinking that with a beer this big, you might need a very high pitching rate. Assuming you didn't use a large starter, was the pitching rate an issue? The reason I ask is because I drafted an extract/adjunct recipe that is very, very similar, but I was planning to pitch a large starter (say 1 gallon) with about 340 billion yeast cells to avoid early fermentation by-products. In other words, can I get by with just a 100 mL packet of yeast?

What would happen if you only boiled for 90 min?

 

[KuntzBrewing]

You would have an extremely watered down version, if your boil off rate is 1 gal/hr that's 4 gals boil off in the recipe compared to a 90 minute boil which would boil off 1.5 gallons,

 

[DesertPunk1981]

But if I started with 2.5 gals less, what would it do to my beer?

 

[krenshaw]

yeah that is quite a long boil.. is that normal for this style? i would love to make something like this, sounds great to keep a case of bottles on hand for people to try, but dont' think i can dedicate that long to a boil..

 

[krzewinskibe]

I brewed a permutation of this...came out EXCELLENT.

Didn't use Borlander Munich, just a standard Munich malt. Also did a double decoction. Probably sat at protein rest too long, but still is wonderful.
