I got this brew in a trade with feloniousmonk, Thanks Al!

22oz bottle served in a standard pint glass.

Black with a small beige head that thinned to a light layer leaving only a few spots of lace on the glass.
Roasted coffee and chocolate aroma.
Sweet roasted coffee flavor all the way through with a hint of some bitterness on the back end.
Medium bodied with a smooth feel.
Easy drinking brew.

I used to see this at various liquor stores with decent regularity, however over the past 8 months it seems to have vanished (the bottled form at least). When I saw a bunch of these at Zipps, I snatched them up. I figured I'd enjoy one and hand out the others as extras.

The color is very dark brown, with ruby highlights when held into the light. Small tan head and a little bit of lacing round out the look.

The nose is a nice combination of roasted malts with a nice toasty, smokey flavor, a sweet malt character, possibly brown sugar and chocolate.

The taste is similar to the nose, with a more pronounced roasted malt character and dark bitter chocolate, roasted coffee and cream. Bitterness from the roasted malts comes out in the finish.

Mouthfeel is medium bodied, with a slow laboring carbonation. Drinkability is great, what a great session brew.

Overall, not my favorite Flat Earth brew, but it's definitely a good one.

Serving glass: Poured from bomber into Nonic Imperial Pint.

Appearance: Very dark ruby-red (almost black) with thin tan head and slight lacing.

Smell: Smoke, roasted malts, chocolate, brown sugar and some spiciness.

Taste: Dry roasted malt with notes of dark chocolate, smoke and coffee. Turns more bitter at the end due to both a spicy and metallic bitterness.

Feel: Low carbonation, smooth medium body, exceedingly dry throughout.

Drinkability: About as dry as a Porter can get - which I like. Hard to stop drinking.

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.

Dark reddish brown with a dense foamy head. Retained the head for the whole glass but left no lacing.

Dark roasted coffee, not much hops and slightly bitter.

Very deep roast and quite bitter up front. The finish is mostly clean but leaves a light bitterness as well. One downside is a slight metallic twinge in the scent that follows in the taste.

Very bright carbonation but not quite at soda pop. Full bodied.

I was good after one of these and had to switch to something different. Not because this was a bad but because it was pretty heavy, even for a fan of porters and stouts.

Grabbed this one at a growler fill night right at the brewery. It's a great time to go in a get to try all of the beers and sodas available. The price is also pretty fair (as low as $9 for a growler).

Bomber poured into my pint glass. Pours a cloudy dark muddy brown with a thin tan head on top. Fair retention, but leaves little to no lacing. Smells like freshly ground coffee right off the bat, then this dulls to scents of earth and bread.

The mouth is pretty average. Some carbonation play, and slight creamy feel. This is a pretty sour porter. The roasted coffee flavors I was expecting are absent. In their place is a sour mineral flavor that isn't all that pleasant. I had higher expectations for this, but I couldn't even finish the bottle. Not impressed.

22oz bomber poured into a snifter.

Pours a very dark black with some light hints of deep brown. Head is small, thick and creamy with a bit of brown hints. Smell is sweet and dry, very malty. A bit of chocolate and coffee.

Taste is really big in the coffee. Come chocolate notes as well, big malt bomb for sure. No hops to speak of. The dark malts linger on your palate for quite a while. Body is pretty light, reminds me of a dry stout (I'm thinking cadillac mtn stout) more than a porter.

Poured a medium brown with an enormous head that slowly faded to a one fingered one. The aroma, while chilled, was vinegar, but as it warmed you could smell the chocolate. The taste too, was very sour, like vinegar cut with soda water. The flavor was helped by warming, but not a great deal, and remained somewhat sour. Feel was light bodied, even for a porter, with only a small amount of carbonation that survived the head. Drinkability was only fair. I had been looking forward to trying something from Flat Earth and was a little disappointed. I had thought that the contents had spoiled or been infected, but too many reviewers expressed similar experience with X-1. Oddly, a large number reported the opposite, a malty sweetness, so something wasn't quite right. Reasonably priced and not terrible, but I'd be reluctant to try again.

A 22 ounce bomber bottle poured into my standard shaker glass. The porter appears a hazed deep brown color with about two fingers of ecru foam. The foam settles to a thin ring in less than a minute leaving no lace behind. Nose and flavor are of medium roasted cereal grain, bittersweet chocolate, slightly spicy, sour, licorice notes, some smoke. Medium in both body and carbonation with a slight alcohol burn as the beer warms up.

So this is a very a good beer. My first by this brewery. Appearance is good, very dark small head and some lacing. Smell and taset are very similar. Lots of bitter chocolat, a vit of roasted nuts and some sweet malt. Not a lot of hop presence, but this is to be expected. Mouthfeel is also good, medium body and slight carbonation. Drinkability is very good.

Big thanks to BDLbrewster for this bottle in trade!

Pours a kind of flat looking dark black into the pint glass. Not flat, but not super-lively looking either. Smells like sweet, not just malt sweet, like there is some fruit in there as well. Taste is a lot different than anticipated. It's actually kind of sour, not really vinegaric, but tart. Like a raspberry tart porter. I thought it might have been a bad bottle, but then I saw others here experiencing the same. It's not really roasty or dry, more sweet. Mouthfeel is pleasant and coating, but drinkability suffered from the unexpected tartness. Not bad by any means, just different.

Opened with signs of high carbonation. nice and loud hiss followed by lots of foam. Visibly fizzy but the lace is gone. I let it warm up a bit.
Smells like sesame oil?! Puts me off abit.
Szchuan inspired?

And yes it leads with an oily sesame flavor. Smokey, with bitter burnt matter. European licorice, the weird German stuff? Bitter moleasses with some dryness.

Kind of thin & astringent with complex flavors. Has some character to it but not my top stand alone porter.

Quite a sipper, I think to fully enjoy this some nice sweet BBQ ribs are needed. Pulled pork. Something with some sweetness I think. Barbeque some thing and enjoy it, as this one won't drink well on its own.

Let's face it, beer is usually ment to be consumed on it's own. I don't have time to get something edible to enhance my experience which is why I've been so harsh with this one.

Here is another Bottle;

I was really excited about this one but never found time to drink it; for one reason or another it's been around for a while.

Chilled in the fridge, I let it warm back up for a few minutes.

Poured out a HUGE volume of foam with only amount an inch and a half of beer. I'm guessing unpasteurized overly bottle re-fermentation. Lots of foam.

Dark blackness. Smells of coffee, dark chocolate, and dark rye bread. Sweet molasses. Very distinguished.

Huge beer. Really syrupy. Burnt carbon flavors, molasses. Slight dryness.
I bet this was so much better when it was fresh.

Decent heft to it but seems too sweet & syrupy.

Clearly needs to be consumed in season.

22 oz. bomber into a pint glass

Pours a dark mahogany color with a two inch light tan head. Retention is very good with some moderate lacing left behind.

Aroma is kind of funky overall. There's definitely some diacetyl, not exactly pleasing. A bit of chocolate, light fruit character. Quite average overall.

Taste is sour up front with some cherry/raspberry tartness. Some of the chocolate character as well but the tartness dominates. Diacetyl also comes through slightly, not really helping it out.

Mouthfeel is medium-light bodied, good creamy texture, but the tartness takes something away from it.

I don't know if this was infected or it was supposed to taste like this, but I definitely didn't like it. Very disappointed.

Wow! This cap cracked with some force. The sound of that surely suggests overcarbonation. Let's see. Pours a dark, nut brown color. There's quite a bit of light getting through revealing nice burgundy highlights. Carbonation is too high. A light, mocha tan head easily reaches four fingers and takes a long, long time to dissipate. It's somewhat annoying. Lacing was nice and thick though. It'd easily be a little better if carbonation were more reasonable.

The nose is nice, but isn't a huge standout. Maybe a little weak. Roasted and chocolate malts are at the forefront and start things off nicely. They're quickly cut off by a strong rye aroma. I'm intrigued. A spicy flavor could...well..really spice things up for the style. Chocolate is resilient and re-emerges. Light coffee is noted toward the end. This is an interesting smelling beer. It's good. I'd like a little more muscle. That might bump it to the next level.

Indeed, this is an interesting English Porter. Chocolate malts and roasted malts (to a lesser degree) give it a nice base. Chocolate malts are more bitter than sweet. The spicy rye flavor is pretty aggressive and really sets this beer apart. Frankly, it wouldn't be very impressive without it. There's a slightly acidic or sour taste to it. It's a little misplaced, but isn't too offensive. Light coffee and a grain flavors emerge at the secondary level. No alcohol is noted. All in all, it's got a nice flavor. The rye is the driving force. Nicely done there.

It features a medium body that feels nice and robust. I'd love to say it's smooth, but the carbonation is extremely high, buzzy, and distracting. They really missed the mark in a big way there. Drinkability is above average, but the excessive carbonation hurts it. It's less pleasant going down as a result. Still not bad though.

My first experience with Flat Earth is a bag of mixed results. The big positive is that it has a nice, interesting, novel flavor due to the rye infusion. The big negative is overcarbonation. Way off the mark. Remedying that problem would do much to improve it. Nonetheless, I like the flavor and approach. Worth checking out.

Purchased in the Twin Cities a few weeks ago and I am glad I only got one bomber. I was really looking forward to trying this beer but it really didn't impress me.

For an English Porter, had some funky smell and taste going on. Not clean. Bottle wasn't infected but it was just Some smoke flavoring but very very thin for this type of beer. I wanted something to stand out and say....yeah. But that never happened. Drain pour..No. But I won't be purchasing another one in a very long time considering there are MANY more better porters out there and for less money. This beer tasted CHEAP. Like it was made at the old Pig's Eye brewery. Come on guys, you can do better. If you are going to use a classic rock band's song for a beer, please make a quality product. I am afraid RUSH wouldn't be proud. No endorements from them or from me for that matter.

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.

Bomber that I forgot about- probably pushing a year old. It didn't explode while in the cellar, so we are off to a good start! Pours a dark ebony with some garnet highlites when held up to the light. Minimal head but fine lacing. Nose- light roast, dark chocolate. Taste- quite dry, surprisingly spicy for style, chocolate, medium fruitiness, nuts. Carbonation is a little high, and the finish is metallic. Drinkability is not too bad.

22 oz. bottle.

Clear maple syrup amber brown body. Large, creamy, lacy, dark beige head. Good retention. Nose is, surprisingly full of sour cherries and lemon tartness. Uh-oh. Some scorched caramel and chocolate detectable, but mostly sour and woody. Taste is, as expected, overwhelmingly tart and sour. Overcarbonated and gushy, with unpleasant woody tartness. It's too bad, because I was really looking forward to trying this beer! Better luck next time Flat Earth.

Sampled on 1-27-09

Pours dark and hugely foamy, almost spilling over the sides of the glass. The foam settles to a thick tower, leaving craggy chunks of lacing.

Smell is clean but malty, with subtle aromas of smoke and anise.

Taste is oddly sour, slightly earthy, and that's about it. Not good at all.

Mouthfeel is super fizzy, and off-putting.

Drinkability is bad, taste and mouthfeel make it a chore to drink.

Overall, gross.

Bottle from Jungle Jim's.

A - Poured a clear dark brown color with a large frothy brown head that lasted with good lacing.

S - Moderate biscuit malt, chocolate and smoke aroma.

T - Medium bitter & sour flavor with a medium bitter finish of moderate duration.

M - Medium body with a dry texture and lively carbonation.

D - My expectations where not met and I hope this was a single bad bottle.

22oz. poured into tulip

Appearance: Dark brown with a small amount of transparency. Quarter inch white head that dissipated fairly quickly. Lot's of effervescence.

Smell: Chocolate and coffee with a lot of roastiness, almost smells like burnt popcorn.

Taste: Coffee hits right away with some slight caramel flavors, light but enjoyable. Then the aftertaste...burnt popcorn. Maybe burnt caramel corn would be a little more accurate but after taking multiple sips there is no doubt in my mind that the flavor is in there. It's really actually quite interesting, I've never tasted a porter like this. There's some very subtle dark fruit flavors in there mixing with some sourness and smokiness but hard to distinguish.

Mouthfeel: This is another surprise with this beer, it's carbonated as hell. Lots of bubbles continuously streaming up the glass and the way the head disappeared looked like I had poured myself a root beer. In the mouth it's kind of a nice kick and makes for a very interesting mouthfeel. I'm having a hard time deciding how I'm going to rate it though...well, I will totally annihilate that bridge when I come to it.

Drinkability: Pretty high, it won't knock you on your ass and it's light bodied.

Overall: I've been wanting to try this for a while and I am kind of mystified by it. Since it was such a surprise I am enjoying it quite a bit and I would love to try it on tap but it just was not what I would expect from a porter. I don't think I would reach for this one to warm me up on a cold night like the bottle suggests, but I will reach for again when I'm at the store. I wonder what a Flat Earth stout would be like?

Bomber poured into an imperial pint glass.

A-Poured with a minimal tan head which reduced relatively quickly. Deep brown beer, was pretty clear when held to a light. Little light passed through otherwise, with garnet highlighting on the edges.

S-Strong aromas of roasty, toasty malts with hints chocolate.

T-Mostly dominated by roasted malt, with nuances of biscuity flavors poking through. Hints of chocolate make an appearance, as well. No hob flavor, with low hop bitterness. A bit of roasted astringency at the finish.

M-Medium-thin body, I think a bit too thin for the style. Moderate, appropriate carbonation.. Silky over my palate, but a bit heavier silkiness would have been preferred.

D-This a good one, and one of my favorites from Flat Earth. Although not spectacular, it's very enjoyable and has been an enjoyable choice on several occasions. Also, nice with a meal, as I enjoyed the second half of the bomber with dinner.

I bought this at Stimmel's in OH for $5.99 a month ago, never seen it for sale again before or since. The beer is dark reddish brown colored, clear but with low light transmission, with an enourmous poofy foam that takes forever to recede. The smell is good, and in fact is the strongest attribute in my opinion. Loads of roasted malt and chocolate. The taste has a surprising amount of sourness in it, so much that I suspect there's something wrong with my bottle (maybe the bottle wasn't disinfected properly before filling, the flavor seems similar to a homebrew problem I had once). Anyway I can still get some chocolate flavor out of if but the sourness makes it difficult to enjoy. I'll try this again if I see it in MN, hopefully from a different batch, and revise the review in case I had a bad bottle.

A bomber of the "newly" bottled version. Shared with Ffejherb.

A-Deep ruby highlighted brown with a medium tan head that reduced to a thin cap and left behind spotty lace.

S-Light roasty malt, a bit of a sour twang with notes of smokiness.

T-Healthy roasty flavours with a bit of a sour twang in the finish. Much like the draft version a subtle smokiness builds in the more you drink.

M-Medium body with with nice lingering flavours.

D-A nice job with the bottled version. Not quite as tasty as the draft is. Nice to have a portable version though.

Headed for the heart of Cygnus
