Crystal 75; Bairds Malt
Crystal 75; Bairds Malt
Crystal or Caramel malts have a distinctive toffee flavour, which becomes more intense as colour is increased, and at the higher end of the colour range burnt or roasted malt flavours may begin to appear. Traditionally in the UK, Crystal malt of colour 70 -80 °ASBC has been used at about 5% of the grist to give the characteristic colour and flavour of UK Bitters and Pale Ales. Adjustment of the amount and/or colour of the Crystal malt may brew some very distinctive beers, but this may require some careful experimentation. Crystal malts have been used in the brewing of Lager beers, but considerable care is required to ensure that whilst a distinctive flavour is achieved, the crystal flavour and colour does not become too dominant. In all beers they can help prevent the formation of oxidised (cardboard) flavours.

Roasted Barley
Roasted Barley
Sweet, grainy, coffee flavor and a red to deep brown color. For porters and stouts.

Maris Otter Pale
Maris Otter Pale
An English thoroughbred and a favored choice of malt for many brewers. Simpsons' Maris Otter has a rich and nutty flavor and despite its small, berry size has a strong husk. This malt delivers predictable brewhouse performance with modest, yet consistent extracts. Brewers can expect good runoffs with clear wort.

Dark Wheat Malt; Weyermann®
German-grown top-quality wheat (2004 harvest). Product Characteristics: Signature malt for Bavarian Dunkelweizen and similar beers. Adds creaminess, body, and complex wheat flavors, as well as some color to top-fermented beers. Recommended Quantities: Up to 70% in Bavarian-style Weizenbiers Suitability (beer styles): Ales: Dunkelweizen, Weizenbock, Weizendopplebock, pub wheat ales, light or low-alcohol beers

- .5 oz
Magnum - 14.4 AA% pellets; boiled 60 min
Magnum
Bred in 1980 at Germany’s Hüll Hop Research Center, this high-alpha variety is renowned for its exceptionally large, heavy cones. Hallertauer Magnum delivers excellent yields and, like many Hüll-developed hops, boasts a strong resistance to disease.
- 1 oz
Willamette - 4.8 AA% whole; boiled 20 min
Willamette
This hop is used for finishing and dry hopping American and British style ales. Aroma is mild and pleasant ans slightly spicy
- 2 oz
Chocolate (unsweetened) - dutch cocoa powder 10 minute boil (omitted from calculations)
Chocolate (unsweetened)
Unsweetened Chocolate is pure chocolate liquor, also known as bitter or baking chocolate. It's unadulterated chocolate: ground roasted chocolate beans with no other added ingredients imparts a strong, deep chocolate flavor in all the sweets you add it to.
- 2 oz
Coffee (grounds) - cold pressed added to secondary (omitted from calculations)
Coffee (grounds)
From the arabica plant. Beans are usually roasted and have a strong distinct bitter flavor. They are then ground and hot water is used to "steep" the unigue oils out of the grounds.
- .25 tsp
AllFine - (omitted from calculations)
AllFine
Clarifier. A purified and standardized form of fish collagen, with a small amount of sodium metabisulfite as a preservative. A free-flowing white powder, mixed into solution in a simple mixer, and normally added as beer is transferred from fermenter to storage. Usage is approx .4-1.2 oz. per 10 bbl. for both ales and lagers.
- .5 tsp
Wyeast Nutrient - (omitted from calculations)
Wyeast Nutrient
Although wort is a good growth medium for yeast, additional Wyeast Nutrient will reduce lag time, improve yeast viability and provide consistent attenuation rates. Low assimilable nitrogen concentrations (FAN) of grape must or wort have long been known as a cause of sluggish or stuck fermentations. Wyeast yeast nutrient, a blend of vitamin B's, minerals, inorganic nitrogen (DAP), organic nitrogen (amino acids), zinc, phosphates and other trace elements will benefit yeast growth and carbohydrate uptake for a more rapid, complete fermentation. Use 1/4 tsp per pint for beer propagation, 1 tsp per 5 gallons for wine or beer fermentation or 1.5 oz per 10 barrels for beer fermentation.

Fermentis S-04 Safale S-04
Fermentis S-04 Safale S-04
A well-known, commercial English ale yeast, selected for its fast fermentation character and its ability to form a very compact sediment at the end of the fermentation, helping to improve beer clarity. This yeast is recommended for the production of a large range of ale beers and is specially well adapted to cask-conditioned ales and fermentation in cylindro-conical tanks. Sedimentation: high. Final gravity: medium. Pitching instructions: Re-hydrate the dry yeast into yeast cream in a stirred vessel prior to pitching. Sprinkle the dry yeast in 10 times its own weight of sterile water or wort at 27C ± 3C. Once the expected weight of dry yeast is reconstituted into cream by this method (this takes about 15 to 30 minutes), maintain a gentle stirring for another 30 minutes. Then pitch the resultant cream into the fermentation vessel. Alternatively, pitch dry yeast directly in the fermentation vessel providing the temperature of the wort is above 20C. Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps. Leave for 30 minutes and then mix the wort e.g. using aeration.

Still In Secondary

Steeped 2 oz of dark roast coffee for 30 minutes then added the cocoa for another 30 minutes. Kept temperature between 160 and 170. Between the time I cooked the mix of the stove 'till adding it to the secondary, a large perventage of the cocoa had settled out. I'm thinking most of the cocoa will end up on the bottom of the secondary. We shall see...
