Darkish beer kinds usually obtain their shade via the usage of roasted grains comparable to Chocolate Malt and Roasted Barley, that are recognized to contribute traits starting from nutty to ashy. Nevertheless, for sure darkish kinds, like Schwarzbier, the roasted character is predicted to be extra delicate, and one ingredient brewers can use to attain this whereas guaranteeing correct shade is Weyermann’s Carafa line of roasted malts.
Roasted to round 310 °Lovibond, Carafa II is claimed to have aromas of espresso and chocolate whereas contributing a slightly gentle roast character to beer. Given the similarity in names, Carafa II is commonly mistaken for Carafa Particular II, which is identical malt that has had an excellent portion of the husk materials eliminated, ostensibly contributing even much less roasted bitterness. It’s this debittered model of Carafa that Weyermann makes use of to create Sinamar, a pure beer coloring that abides by the Reinheitsgebot and imparts a darkish shade with minimal roasted flavors to beer.
I’m an enormous fan of Schwarzbier, although recent industrial examples are troublesome to come back by in my space, so I lastly determined to brew a batch myself. When contemplating the recipe, I recalled conversations with associates about utilizing Sinamar rather than roasted grains with a purpose to get shade with little influence on different perceptible traits. Somewhat than decide only one, I made a decision to check a beer made with this liquid coloring agent to 1 made with Carafa II malt.
| PURPOSE |
To judge the variations between a Schwarzbier made with Sinamar and one made with Carafa II.
| METHODS |
Being my first time brewing a Schwarzbier, I designed a recipe that was loosely impressed by others revealed on this website.

After amassing 2 units of water and lighting the flame to get them heating up, I weighed out and milled the grains, leaving out the small quantity of Carafa II within the batch that might later be dosed with Sinamar.
As soon as the water for every batch was adequately heated, I integrated the grains then checked to ensure each had been on the identical goal mash temperature.
Whereas the mashes had been resting, I ready the kettle hop additions.
As soon as every 60 minute mash was full, I eliminated the grains then boiled the worts for 60 minutes, including the Sinamar to 1 batch as quickly as the warmth was reduce.
I then proceeded to relax the worts with my JaDeD Brewing Hydra IC.
Refractometer readings confirmed each worts achieved the identical goal OG
Left: Sinamar 1.052 OG | Proper: Carafa II 1.052 OG
I racked equal volumes of wort from every batch to an identical fermenters then positioned them in my chamber managed to 50°F/10°C. When the wort temperatures had been steady just a few hours later, I pitched a pouch of Imperial Yeast L13 International into every.
The beer was left to ferment for 4 weeks earlier than I took hydrometer measurements indicating a really minor distinction in FG.
Left: Sinamar 1.008 FG | Carafa II 1.009 FG
At this level, I transferred the beers into CO2 purged kegs and positioned them in my keezer the place they had been left to lager for six weeks earlier than they had been able to serve.
Left: Sinamar | Proper: Carafa II
| RESULTS |
A complete of 42 individuals of various ranges of expertise participated on this xBmt. Every participant was served 2 samples of the beer made with Sinamar and 1 pattern of the beer made with Carafa II in numerous coloured opaque cups then requested to determine the distinctive pattern. With a purpose to attain statistical significance, 20 tasters (p<0.05) would have needed to precisely determine the distinctive pattern, which is exactly the quantity that did (p=0.038), indicating members on this xBmt had been capable of reliably distinguish a Schwarzbier made with Sinamar from one made with Carafa II.
The 20 members who made the correct choice on the triangle take a look at had been instructed to finish a quick desire survey evaluating solely the beers that had been completely different. A complete of 10 tasters reported preferring the beer made with Sinamar, 8 mentioned they favored the beer made with Carafa II extra, and a couple of had no desire regardless of noticing a distinction.
My Impressions: Out of the 5 semi-blind triangle checks I tried, I appropriately recognized the odd-beer-out each time. Whereas the beers shared many similarities, I perceived the one made with Carafa II as having barely extra roast character than the one made with Sinamar, which had primarily no roast. Whereas I assumed each had been scrumptious examples of Schwarzbier, I had a slight desire for the one made with Carafa II.
| DISCUSSION |
The colour of a beer provides the drinker some indication of the way it’s going to style, and with regards to darker kinds, the expectation is that it’ll possess some degree of roast character. Nevertheless, Schwarzbier is a method that, whereas inky black, possesses a delicate roast character, which it typically will get via the usage of milder roasted grains like Carafa II. For brewers in search of shade with even much less influence on taste, there’s Sinamar, which is of course produced from dehusked Carafa. The actual fact tasters on this xBmt had been capable of reliably distinguish a Schwarzbier made with Sinamar from one made with Carafa II suggests the completely different elements might impart distinctive traits.
On apparent potential clarification for these outcomes has to do with my use of Carafa II, which possesses grain husks, slightly than Carafa Particular II, which is the dehusked model that’s used to provide Sinamar. Then once more, tasters in a latest xBmt had been unable to inform aside beers made with both Carafa II or Carafa Particular II, so it’s doable another issue was at play.
Whereas I completely loved each of those Schwarzbiers, the slight roast character I perceived within the model made with Carafa II was extra in step with what I’ve expertise when consuming industrial Schwarzbier, and I tended to want it over the one made with Sinamar. I stay up for exBEERimenting with this distinctive ingredient extra sooner or later, however as for now, I’ll be sticking with grains when making future batches of Schwarzbier.
