I am brewing an Imperial Stout (OG 1.081) and it is in primary now. I want to rack to secondary in one gallon jugs and want to flavor each differently. I have read through the coffee posts on here but cannot find good recommendations for exact measurements and methods.

The question. For one gallon how much coffee should be used.

I was going to lightly grind the beans (low acid light roast) and "dry hop" them in secondary. A range of how much would be nice as I can do one gallon strong and another lighter.

Second question The same except using chocolate. What is the best method to get this flavor in at secondary.

Also if there is a good way to do a something with cherries or star anise at this point I would like to try those as well but again, I need good measurements and methods.

EDIT: I want to use ground coffee beans and probably cocoa nibs (the best use of chocolate in secondary I have found)

For how much coffee to use, check out the recent "Can You Brew It" where they tried to clone Terrapin's Wake-n-Bake stout. They worked from the exact recipe as given to them by the brewer at Terrapin. You can even buy the same blend of coffee they use commercially, if that interests you. I just listened to it this week because I also have a big stout sitting in the primary that I'm going to add coffee & chocolate to. Unfortunately, I don't remember exactly how much they used, because they added ground coffee to the secondary, like you plan to do. I'm going to do it differently.

My plan is to cold brew about a pint of sumatra mandheling using my French press. I'm going to make it a good bit stronger than if I were hot-brewing a cup for myself, probably twice as much coffee as I'd usually use. That would mean two heaping tablespoons (instead of one) per four ounces of water. I'll let it soak in pre-boiled, cooled water in the fridge for about 12 hours, then I'll press it off and pour it into the secondary before racking in the beer.

For my chocolate flavor, I plan to use cacao nibs. I got a bag of cracked ones as a gift. I want to sterilize them, so I plan to soak 8 ounces of them in some Maker's Mark overnight, then add the nibs and the bourbon to the secondary with the coffee before racking. I've never used nibs before, but I've read stuff from people who have and they were happy with the results. 8 ounces seems to be the sweet spot to get good-but-not-overwhelming chocolate flavor. The bourbon will add a bit of flavor, but it shouldn't be overpowering. Last night I did an experiment where I mixed 1/2 tsp of bourbon, 1/4 tsp instant espresso, and 1/4 tsp cocoa powder into 1 oz. of Fuller's London Porter, stirred it well to dissolve everything, then poured in the rest of the bottle. The bourbon was just barely there as a background note. The overall taste was pretty much what I'm looking for in my stout (except, you know, the base porter had less dark malt bitterness and the cocoa powder made it look like a glass of nesquik).

Are these measurements for 5 gallons? –  Bullet86 Feb 3 '11 at 15:10
    
Yes, these are for five gallons. I've never done this before, I've just based my plan on what I've read here and there from people who have. How much to use is pretty subjective, but having the Terrapin WnB recipe should help a good bit if you can get a bottle of that beer to get a taste for those levels of coffee & chocolate in one beer. –  JackSmith Feb 3 '11 at 15:49
    
Listend to the link you posted and got these measurements: 14.6 grams of coffe (rough ground) per gallon. using 60% costa rican, 20% zimbabwe, and 20% guatemalan. These being added to secondary fermentation and left to sit for 48 hours. I think I am goping to try one gallon at this recipe and a gallon at 75% of this to see the difference in strenght. Will post results when finished. –  Bullet86 Feb 4 '11 at 6:45
    
Came out way to strong. It tastes like drinking cold espresso with a stout finish. I am going to try again and next time do 4 - one gallon batches. 2 with half the coffee and two with the same amount but half the time in secondary. I will let you know what happens. –  Bullet86 Mar 4 '11 at 13:45
    
Is Terrapin beer available in your area? If so, grab a bottle of W-n-B and try it next to your beer to see how they compare. I'll be first-tasting a carbonated bottle of mine today where I followed the steps I described. I'll post back with how it was. –  JackSmith Mar 4 '11 at 14:51

The easiest way to do it is not add flavorings to the fermenter or kettle. Add them after the beer is fermented so you can test and control the amounts. After fermentation, before bottling or kegging, I pour 4 2 oz. samples of the beer. I does each with a different, measured amount of flavoring then taste. I pick the one I like best then scale that amount of flavoring up tio the size of the batch.

Upvoted, with this caveat: this is great advice if you're working with instant flavoring, such as fruit & chocolate extracts, liqueur, or brewed coffee, but unfortunately you can't get such instant feedback if you're adding flavors that take time to incorporate, such as fresh fruit or preserves, cacao nibs, coffee grinds, vanilla beans, or oak. –  JackSmith Feb 3 '11 at 17:45
    
Downvoted because this is just telling me that I shouldn't do it the way I am planning, secondly it doesn't talk about use of flavorings I am going to use. just extracts. –  Bullet86 Feb 3 '11 at 21:50
