I think Oberlin's water is too alkaline, so tried 5g of citric acid this time. Phosphoric might be a good alternative, too. Lots of color from steeping; probably the Carafa malt. I had the Sinamar handy, but don't think I need it. If this scotch ale comes in dark enough, I know where my stouts are coming from in the future.
|
|
Sweet wort tasted good at pitching; so I have hope for the product. The cinnamon and pepper should add presence without identifiable flavor at this concentration, according to that Mosher fellow. May be...
|
|
Some sips I think I taste the pepper, others not. Perhaps just a bit less nest time. The cinnamon also skirts the edge of detectability. The smoke of the peated malt adds a grace note, but isn't dominant; a good quantity. I like this one! It's about what I wanted.
|
|
Cinnamon and black pepper added at end of boil, all others at start. Acid and bicarbonate reacted, of course, but I think I needed the carbonate anyway.
