Jamaican Breakfast Stout Brew Session

Brew Session Info

(Include any important notes from brew day until tasting)

pH settled to 5.4 without baking soda, so added only 0.4g to, roughly, hit 5.5. I rehydrated all of the yeast before I pitched it in distilled water. I wanted the OG much higher but I can't get the wort to boil very well with the lid off on the stove, so my boil off rate sucks. I need to try to boil on the propane in the garage with these bigger beers. 2/11 - putting all the secondary additions and will let the nibs and wood chips soak for 2 weeks. I will remove the coffee after 2 days.

Gravity Estimates

Based on boiling 5.20 gallonsliters at 1.048 for 90 minutes, this will decrease your wort by 1.50 gallonsliters, bringing your after boil OG to 1.062.

You wanted an OG of 1.080. It looks like it will be under.

Notes:

Pours 1 finger of foam that slowly dissipates, very dark but slightly mahogany when held to the light. Aroma is roasted grain, coffee, and a slight twang from the barrel chips. Flavor is a malty chocolate that quickly transforms into roasty barrel followed by a breath of vanilla and roast. Body is medium and nucleation is a touch sharp. Overall, this is a great start on a barrel aged stout as the barrel flavor isn't overbearing. I couldn't pick out rum from the barrel and, also, the body isn't as dense as I hoped and the nucleation is too sharp for the style. 4 stars.
