Brewing: Great Fermentations Dark Side Robust Porter


Great Fermentations Dark Side Robust Porter is a rich, roasty and robust traditional English style porter.  It is available in both all grain and extract versions.  The all grain version features Maris Otter for the base malt, a generous amount of brown malt and Simpson’s Medium Crystal and Chocolate Malt.  It receives two charges of Fuggle hops.  Yeast Suggestions are Wyeast #1098 British Ale, Wyeast #1275 Thames Valley, Wyeast #1099 Whitbread Ale, Imperial Yeast A01 House or Safale-04 dry yeast.


“A true English style robust porter, straight out of the pages of history! The Dark Side Robust Porter uses a healthy dose of Brown malt, a malt that porters traditionally used as their base, to add a heavy robust character to the beer. Notes of coffee flow forth in the flavor profile, aided by some chocolate malt and balanced by some crystal malts from the U.K. Add some English Fuggle hops on top, and you’ve got a robust porter that finishes big with a hint of sweetness. Once you go to the dark side, you may never go back!”

It is well balanced, allowing both malt and hop character to shine in the finished beer. This yeast is clean all around, but will produce more fruity esters as temperature increases. While it works well on American IPAs and pales, it can be used in a plethora of ales, both British and American. This yeast is highly flocculant and will drop out of solution after fermentation, yielding brilliantly clear beers. A great choice for a house strain in your home brewery!”cln_img_0388To sanitize.  I soaked the top of the can in Star Sancln_img_0392A quick look at the open cancln_img_0434A01 calls for a fermentation temp of between 62 and 70 deg F.  I cut it about in the middle at 67 deg F.  Here is my Inkbird Dual Stage Controller at the beginning of fermentation.  Toward the end of fermentation, I bumped it up a couple degrees to help encourage the yeast to clean things up.cln_img_0674Kegging.  Beautiful looking beer.cln_img_1003The finished beer in a Spiegelau Stout Glasscln_img_1005I thought it appropriate to serve this beer on my dark grain Mashed.In tap handle.

This is a straight up delicious beer.  The brown malt, crystal and chocolate malts produce roasty, coffee, chocolate flavors.  As  the beer warms up on your mouth, these flavors pop.  This is a delicious English style Robust Porter.  This was one of those beers, that I was concerned that I would run out of before getting the final picture for this post.
