This beer pours a dark mahogany, almost black color. The head is large, creamy, firm, and recedes very slowly into a thick cap of foam. The aroma is of chocolate, whiskey, oak, and burnt caramel. The taste is of oak, vanilla, whiskey, dark chocolate, and toffee. The mouthfeel is medium bodied, creamy, silky, and has adequately mild carbonation. Overall, this is a great porter. It is complex without being overpowering, and is very drinkable. I can see this becoming a regular in my fridge.

4.8/5  rDev +26.6%

One of the better porters I've had. Color: Dark but transluecent. Smell: Roast nut and chocolate, very inviting. The rye reminds me of bourben which I also like, but the beer taste does not. Taste: Flavor explosion, hints of chocolate, roast malt, somewhat bready without thichness, perfect balance of sweetness and hop bitterness without being overpowering in either. Mouthfeel: could be a little thicker with more carbination. Head really never formed and beer left a thin lace on the glass. Drinkability: goes down easy, could be a session beer. First beer I've had from Flat Earth...I'll definately come back for more Cygnus X-1

Purchased in bomber at Rum River Liquor. ABV 6.5%

4.63/5  rDev +22.2%

Poured from 22 oz bottle into shaker pint glass.
A: Bottle opens with loud pop...tons of carbonation (which for me was a drawback...poured 1/2 of beer and got a 4+ inch head). Color is very dark amber. Extremely large tan head produced from the high carbonation.
S: Nice aroma! Roasted malt, sweet honey, toast, and a hint of dry dark chocolate.
T: Wow! Very fresh, dark, and complex. Roast chocolate malt hits first and this transitions into a dry smokey toast finish. Very nice.
M: Light body...wish the taste lingered a little longer. Extreme effervesence from the high carbonation.
D: Damn! I wasn't expecting this. Once I got beyond the ridiculous carbonation (and if they toned that down I would give this a higher score), this is one hell of a beer. Elements of a porter, smoke ale, as well as a milk stout come through. The end result is amazing!

On tap at The Happy Gnome in St. Paul served in a snifter.
A - Very dark brown color with a nice white head.

S - Roasted malts are first present with subtle hints of coffee and chocolate and a mild hop sweetness.

T - Roasted malt character is the first taste but as drink this beer you notice hints of coffee, chocolate and eventually a nice smooth hop sweetness will come through.

M - Nice and silky smooth mouthfeel. Very enjoyabel brew with a nice mild hop finish.

D - Very drinkable. This beer drinks very easy and such a nice mouthfeel that you are always left wanting more. A wonderful tasting porter. I hope to see this beer in bottles soon. In my opinion this beer could easily rank up as one of the better Porters out there.

4.53/5  rDev +19.5%

Bomber poured into a pint glass. Sort of light in color. Closer to the red end of the porter spectrum than black. Settles somewhere around auburn in color with a fluffy beige head. Aroma of See's Candies, mocha coffee, roasted grains. Nice, robust smell carries over into the flavor, which is similar but not as sweet. Black malts meld with a creamy iced coffee character. A porter through and through, not even remotely stout-like (this is an attribute I quite like, providing much needed separation between the styles). Very little roastiness or bitterness. Finishes dry. Mouthfeel is full and almost milky in consistency. Really a sublime porter in every way.

I initially had this on tap at a Flat Earth brewery tour and immediately ran out and bought several bombers.

Pours from the bomber bottle a beautiful brownish-black color. Appears black for the most part but as I look through the pint glass you can almost see through it. There are brownish hues reminiscent of dark chocolate. The aroma is quite nice w/ chocolate and coffee aromas up front followed by some mild caramel scents. When it comes to taste, the aroma didn't lie. Strong coffee and chocolate flavors. There is some uniqueness w/ this as you can taste the slightly bready rye malt. Not a lot of bitterness, which is desirable. Very smooth and comforting. The mouthfeel is like velvet. A little overcarbonated initially, but as you let it rest, the true texture pans out.

Overall, a phenomenal porter. It fits the syle perfectly w/ a charming uniqueness. I will be picking this up again for sure. I had one the other night and found myself craving it all day at work. Truely a fine creation from a great brewery.

4.4/5  rDev +16.1%

A= pours a black color with a nice deep amber coming through with the light. the head is just a little off white not quite as dark as i like but it does have nice thick bubbles with some nice retention. its about a finger high and falls to a "thick" skin on top with pretty decent lacing.
S= nice and roasty. reminds me of the reason I fell in love with craft beer. that nice roasty smell. black burnt malt. possibly the slightest dark chocolate. really just nice and roasty though.
T= again really nice roasty smell. the taste reminds me a lot more of coffee than the smell led on to be. loads of roasty smokey flavor. much more roasted then smokey. really good but also somewhat light which leaves me coming back for more and more sips as the delicious taste leaves my pallet. prolly not the best thing for taste but great for drinkablility. I do notice a nice roasted taste in the back of my throat along with a small amount of hop bitterness tickling around back there.
M= Really what you would expect from a porter. They didn't try to go crazy making this creamy or super smooth. they really let this be a nice porter.
D= As I mentioned in the taste portion I think the taste of this beer is somewhat mild and delicate so I find myself constantly coming back for sip after sip to keep the delicious taste on my tongue. Great representation of a porter and really reminds me of why I began drinking craft.

4.4/5  rDev +16.1%

Appearance: Very dark brown, opaque. 2 fingers of white lacy head that stuck around for a while.

Nose: Roasted malts, a bit of chocolate. An unexpected grassy malt smell from the head. Once the head dissipated it wasn't as prevalent and the roasty chocolate smells were much more pronounced.

Taste: Much better, none of the grassy smell. Roasted malt tastes prevail but there is an interesting smokey character not usually present in a porter. Interesting dark chocolate, creamy finish.

Mouthfeel: Very good. Medium-heavy body. Coats the mouth well. Maybe just a tiny bit too much carbonation.

Drinkability: Very good. A very enjoyable beer.

Poured into a pint glass this beer came to me with a frothy and thick light brown head. Appearance is deep reddish brown, almost black from a distance. Once it settled the aroma is of chocolate, bready goodness. Taste, oh the taste. Let's see...chocolate malts, grassy hops, a hint of smoke, and oh so easy to drink. The grassy hop bitterness balances really nice with the dark malts. This beer could use a bit more mouthfeel and then it would be 5 for certain. Don't miss this gem!

4.35/5  rDev +14.8%

Poured from 22 oz. bottle into a Sam Adams perfect pint glass.

Appearance: Very dark cola like amber brown. Lots of rising bubbles. Big three finger lightly tan head with great retention and very good lacing.

Smell: Strong aroma of dark roasted malts with a good amount of chocolate and coffee. Hints of dark fruit, rye, and floral hops. Has a very toasty smell.

Taste: A sweet taste from the roasted malts, grains, chocolate, coffee, and dark fruits. Has a hint of rye in the middle and a light hint of hops in the finish. Strong with the fruity sweetness but it is well balanced.

Mouthfeel: Medium bodied with a medium carbonation. Very creamy, toasty, and smooth.

Overall: A very good porter from Flat Earth. One of the better ones I have tasted.

4.35/5  rDev +14.8%

A: Poured a pretty thin head, but I poured a little soft, so that may have been it. Looks like a very dark cola almost with some good active carbonation. Reddish when held up the the light. 22 oz Bottle is a picture of space, but what is most interesting in this information, printed on the side:

English Pale, Brown, Amber, Chocholate and Rye Malts; fuggle hops; Irish Ale Yeast and St. Paul Water.

O.G. - 1.065
SRM - 25
IBU - 35
Alc. by Vol. - 6.5%

S: A sweet malty roast filled the air when I popped it open, and upon closer inspection, I found some good burnt caramel smells that I liked.

T: Taste is very complex, probably from the 5 malts they use ranging from english pale to chocolate and rye. Some roasty flavor, but still pretty sweet. Very low bitterness. Sweetness increases as my tounge becomes used to the roasted flavor. Actually quite similar to a heavy cola.

M: Creamy and a good weight without being too thick and chewy. great smooth texture. Very enjoyable

D: Very easy, very smooth. A pretty standard ABV, so not really sessionable, but if you have the tolerance it won't fill you up.

On tap at The Muddy Pig, this pours a clear brownish black color, with a brownish head and ample lacing on the glass. The smell is of raisins and malt. The taste includes raisins, plum, a slightly smoky flavor and dark chocolaty malt. There is a slightly hoppy finish, bringing a nice balance to this beer. The mouthfeel is smooth and refreshing. This is a terrific porter and is yet another great reason to drink Flat Earth beers.

Mahogany color with ruby highlights and a beautiful, two finger, light tan head with nice retention. The aroma is roasted malt, coffee, rye, and bitter chocolate.

The taste is incredible. It has all the flavors of the aroma, is mildly sweet, mildly bitter, and the best part is the roasted malt. This is one of the best tasting porters I have had in a long time.

Smooth, medium bodied, somewhat dry. and nicely carbonated. This is very drinkable, and very nice. I must seek this one out again.

Some confusion at first on this one...one source initially called it a "Canadian Bourbon-Infused Porter"...others set the record straight and dubbed it an English Porter, brewed with rye...that's more like it...so, I went and had one at Ye Olde Happy Gnome, and here's what I thought...

Poured to the top in a Flat Earth snifter/goblet...full-on blackness, thin ring of roasted cocoa head. Very nice.

Roasty nose, dark chocolate, some anise, molasses, slightly sweet and still toasty/roasty...the kind of porter-y aroma that makes me want to keep my nose in there and search out more delights.

Smooth, even-handed on the tongue...medium- bodied, rich in porter-y goodness, then dry sliding out. Some caramel peeps out in the flavor, nicely roasted, but I end up wanting more body from this guy.

Good effort, though...one of my favorite Flat Earths, and one I'll try again, for sure. Good to see more quality dark brews coming out from the locals.

On tap at the Gnome, Flat Earth has a winner with this one. Nice dark brown pour into a snifter. the Aroma is a nice roated sweet malty and the flavors give off the much of the same. Silky mouthfeel that slided right down, and I could drink this one all night.

Way to go on this one FE.

Black at first appearance, but proves to be a rich, deep mahogany when held to the light. Light tan, two-finger head that recedes fairly quickly, becoming patchy yet full around the perimeter.
Smell is pleasantly bold, with coffee and fairly dark chocolate dominating, with a nice smokiness accompanying. Malty tones as well.
Taste is smokey malts, with coffee and faint dark chocolate. A woody smokiness remains through the finish.
Mouthfeel is very appealing. Nice bite from the carbonation, which also gives it a pleasant crispness, which yet still allows for enough smoothness to round it out quite well.
Very drinkable. Relatively low ABV and everything else I've noted make this one go down easily. I'm glad this is a bomber rather than a 12 oz. bottle.

Huge thanks to Lordsloth for sending this one down to me!!

Flat Earth certainly seems to have whatever bottling problem they were having fixed as this poured out a glorious ruby-brown color and loads of head and carbonation... Huge head of tightly packed bubbles, shelves of lacing down the side of my DFH pint glass..

Aroma of dark roasted malts, maybe a hint of chocolate malts and perhaps a touch of smoked aroma... Interesting...

Wow, this thing is much different than I was expecting.. Very unusual taste for a porter.. Perhaps its the combo of the rye malts and the smoke.. Whatever, it works here... Big time.. Starts out good and gets better as it warms and some of the complexity is revealed.. The rye pops out and gives this a spiciness that you just don't find in other porters..

Magnificent brew here... Different, but in a very good way..
