look: 4 | smell: 5 | taste: 4.5 | feel: 4.5 | overall: 4.5

Good brown beer but pours nearly black so takes away from the brown label. Taste is like a malty, chocolatey nutty ale but no nuts or chocolate are in the ingredients. But had this beer in Yosemite waiting for the road to clear and hit the spot for the moment. But should've had it the night before but mammoth brewery closed hour early and couldn't enjoy at brewery. So shame on the brewery for closing early.

With a dark mahogany color, this beer has a smooth, malt-forward taste of nicely roasty milk chocolate, dark bread and toasted biscuit with a smidgeon of dark fruits and even black tea. These flavors combine together very well, all the way into the aftertaste. It’s nicely sweet with a fantastic mouthfeel for the style. Meanwhile, the aroma is very pleasing to the nose, which is very similar to the flavor. Along with the Black Toad ale from Trader Joe’s, this is THE alternative to the outstanding Nut Brown Ale from Goose Island Brewery. That brewery needs to bring that back! Other good nut brown ales to try are those from the Carolina Brewing Company, the Santa Fe Brewing Company and even the Coconut Molasses Brown Ale from Duck Foot Brewing Company. While not a nut brown, the Salted Caramel Brownie Brown Ale from New Belgium Brewing is also worth the mention.

Black with fairly small head for a porter. Smells of cocoa powder. Tastes of chocolate with a tart, vaguely fruity aftertaste. Overall, the taste is a little weak and the mouthfeel is too watery.

look: 1.75 | smell: 3.5 | taste: 3.5 | feel: 3.25 | overall: 3

Pours similar to Coke that's gone flat. Fizzy up front, fading to nothing. No head, no lace. Zero. Nearly opaque, extremely dark brown tint. No bottle date, but doesn't smell off, actually smells quite nice. Very nutty and roasty, hazelnuts and fresh roasted coffee. Hot chocolate. Not bad.

Doesn't taste bad either. Lots of hazelnut, acorn, light almond and tree bark notes. Very earthy. Roasted malt and coffee come through nicely, accompanied by smooth chocolate, toffee, a bit of dark fruit, oats and grain.

Light bodied Porter. Light carbonation. Light getting roastiness. Gas station coffee.

A very unattractive brew that comes through with some good flavours and finish, but needs some nuancing. Ultimately leaves me unsure how to feel about it.

look: 4 | smell: 4.25 | taste: 3.75 | feel: 3.75 | overall: 3.75

Bottle poured into a Mammoth Brewing Co pint glass

A: Pours rich brown with some ruby hues, a frothy khaki head that settles to a thin layer and laces lightly.

S: Nutty toasted malt, a little chocolate and coffee, touch of dark fruit, little dark caramel malt sweetness.

T: Toasty malt, coffee and chocolate notes, little dark fruit, nutty, and a kinda burnt toast bitterness. Not as robust as the smell would lead you to believe.

M: Medium body, moderate carbonation.

O: Not terrible, but I wish it tasted as good as it smells.

look: 3 | smell: 3.25 | taste: 3.5 | feel: 3.25 | overall: 3.25

Poured from a 12 oz bottle.

L - Dark mahogany color, but looks clear when held up to light. Headis light tan color. It starts weakly and fades to a thin ring around the glass.

S - Aroma is bready, with some slightly singed grain. Some chocolate. There's a strange funky hint in the aroma, like milk just before it sours. No hops aroma.

T - Bready malt flavors with chocolate/chocolate milk and some plums. No overt burnt flavors. No hops flavors, but some mild bitterness. No yeast character. The almost-sour aroma is not reflected in the flavor.

F - Thin to medium body. Low carbonation with a silky, velvety feel (oats?). No obvious alcohol.

O - Overall, I find this a bit thin and too low in carbonation. The flavors are good, but nothing really stands out. Strange note in the aroma.

mine says 5.5%....
pours thick, dark mahogany color. head dissipates quickly on the soft pour.
aroma is sweet, nutty and toasted.
flavor is a little sweet. very nutty and a little roasted malt. caramel. molasses. thicker than some other nut browns I have been drinking recently. I like it. I like it a lot. i'd love to rate it higher for its style but in general the browns don't seem to get much respect. there are a lot of generic browns with some corn-kind of flavors but this one is a great brew. highly recommended. maybe when the "bros" rated it it was a different recipe?

Thanks to WST for this one!

Pours a dark chestnut brown that looks black, until it's sharp clarity is visible in the light. Creamy tan foam, sticky around the edges, though not much lace later on though.

Nutty, husky toasted malts in the aroma, hints of molasses.

Tastes similar, lightly roasted malts, some caramelization, though dry and chalky in the aftertaste. Supple feel, medium bodied, slightly astringent. Overall it's almost more of an imperial brown than a porter, a hybrid of the styles. Review #3600

Pours a dark brown color and has a fairly thin off white head. The smell is sweet and vanilla chocolate with heavy roasted nut. The flavor is very nutty like roasted pistachio mild sweetness a little bitterness. The mouthfeel is very carbonated. I'm a real big fan of this beer.

3.9/5  rDev +2.9%

The best of the mammoth beers I had. This is a chocolatey brown ale and porter middle ground that has a ton of toast and cocoa grain flavor but also a real clean finish and not much of the bitter roasted barley I expect from a porter. I don't get the name here though, nothing double about it at six percent abv. It's got some red when held to the light but looks more brown than anything else. Lots of dry cocoa malt flavor all through it and a toasted marshmallow thing too. It's rich but still real drinkable. Good early fall beer, right on for this time of year because of the denser flavor sand approachable body. Good brew all up.

look: 4 | smell: 3.25 | taste: 3 | feel: 3.75 | overall: 3

Rather sweet and roasty, with a watery refreshing mouthfeel. Very big foam in the Peroni lager glass, and quite persistent. Dark brownish red in color. Plenty of sudsiness on the tongue. Aroma of toasted grain and buckwheat.

Rather sweet and malty with the nutty toffee taste. Some flavor of old coffee and burnt sugar. Something piney along with a hint of licorice and cooked wheat cereal. There is a hint of herbal hops, but mostly it's the dark coffee with a hint of burnt raisin toast.

This has that peculiar kind of sweet, medicinal bitter aftertaste that I'm not crazy about. It reminds me of Mexican malt liquor. From the 22 oz bottle purchased at Bine & Vine in San Diego.

A: Pours opaque dark bown with a creamy mocha head.

S: Nutty malts, roasty malts, toasty malts, medium roast coffee and milk and dark chocolate in the nose.

T: Chocolate, orange, nutty and roasty malts, bready malts, coffee and milk chocolate. Quite tasty.

M: Medium bodied and smooth.

O: Definitely recommended. Everything this brewery makes is worth a try.

look: 4 | smell: 3.5 | taste: 3.75 | feel: 3.5 | overall: 3.75

poured dark brown almost black with off white head from a bomber

nose- tootsie roll, chocoalte and caramel, nuttiness, leafy hops

taste- sweet and mellow roasty malts with chocolate, coffee, hop citrus, finishes dry roasted malt with tobacco

feel- fairly thin/watery, roasty, sweet

not a bad brew, definitely enjoyable when on the mountain. could be a little more robust

look: 4 | smell: 3.75 | taste: 4.25 | feel: 4 | overall: 4.25

22 bomber

Appearance- finger and a half of velvety cream colored head, dark brown to the porter colored spectrum

Smell- caramel and chocolate that is impossible to avoid even at a good distance away from the glass, toasted malts are very dominant over the hops

Taste- sweet chocolates on the front and middle with brief roasted bitterness on the end, hints of toffee also add to the mid-tounge feel

Mouthfeel- medium/full bodied with slightly milky consistency and lingering sweetness for a time

Overall- a damn good representation of a brown ale. This is one of my favorite styles, and most certainly deserves another

look: 3.5 | smell: 3.5 | taste: 3 | feel: 3.25 | overall: 3.25

A: Root beer color, typical of porters, I'd say dark cherry brown is the right color. Moderate amount of head--dissolves at an average pace.

S: Smells like dark roast coffee grounds, not terribly complex. Creamy smell. Scents are not overwhelming--a few simple smells, but they come across as refined.

T: Alcohol overpowers taste. Tastes slightly... sour. Not terribly thick, slightly burnt. Finishes pretty cleanly but the burnt/sour taste is distracting. A little more watered down than I was hoping. Maybe the coffee grounds are burnt. Can't say I enjoy this brew right now. 2nd half of the glass tasted slightly better.

M: Move it around a bit--it gets quite foamy. Probably the best part of this beer, besides the simple and refined scents. The foam isn't sour, but doesn't finishes more sourly than drinking the beer itself.

O: I wish I could say this porter was thick and rich--two qualities I feel every porter should have. I can't say the taste is bad but I can't say this is a great porter, honestly. Maybe this would make a better sour brown ale. The mouth-feel and pleasant smell increased this porter's redemption rating from "Slightly-Below-Average" to "Okay".

EDIT: This was my full review during a blind taste test.

Bottle I brought to share at Oneinchaway's tasting.

Pours a hazy dark brown with a foamy khaki head that settles to wisps of film on top of the beer. Small dots of lace form around the glass on the drink down. Smell is of toasted malt, caramel, and roasted nut aromas. Taste is much the same with caramel and nutty flavors on the finish. There is a mild amount of roasty bitterness on the palate with each sip. This beer has a lower level of carbonation with a slightly crisp mouthfeel. Overall, this is a pretty good beer with a solid roasty, nutty presence in the aroma and flavor.

The beer had a dark brown and clear body. Poured into a pint glass with a half inch head. The mouth feel of this porter is light bodied and crisp. Mild hops and medium malts are balanced on the senses. The beer lingers with a chocolate nose and after taste.

A thin head, on a deep, dark brown body.
The aroma is a wonderful roasted malt and a little dark chocolate.
The taste is moderate bitterness balanced well with the roasted malt and chocolate sweetness.
A fairly crisp texture, moderate carbonation and medium body.
A delicious beer.

This was the second Mammoth brew I picked up on a recent road trip. Glad I could share this one.

It pours a dark coffee cola color with light tan foam resulting in a nice and creamy looking head.

I get mellowed toffee and cocoa on the aroma, rounded by a pleasing roasted malt.

A mellow roast comes across flavorwise, followed by a pleasing cocoa note and some sweetness to it. Lightly bodied with a pleasant effervescence. Warms well. This reminds me of a cross between a nut brown ale and a sweet porter.

120z bottle thanks to DeanoMac poured into Founders snifter.

A- Pours a very dark brown almost black that is slightly translucent, but mostly opaque. When pouring it a very thin bubbly light mocha brown head forms that quickly disappears to leave pretty much no head. Appears to have decent carbonation.

S- Lots of espresso immediately hits the nose, followed by roasted malts, almonds, a variety of other nuts. Definitely above average aroma strength. At first it smelled very good with the espresso, but the more I smelled it the less it appealed to me.

T- Light espresso, roasted malts, a tiny bit of chocolate and nuts on the finish/aftertaste that lingers. Not as flavorful as I was hoping and the flavors weren't the most appealing. As the beer warms a more of an artificial taste comes out that is a little bit syrupy.

M- Way too thin, overcarbonated, fairly easy to drink but not the smoothest. Definitely the downfall of the beer.

O- This beer was okay. The appearance was average, aroma and taste were decent but not the most pleasant I've experienced, and the mouthfeel is definitely the downfall of the beer. As the beer warmed up the nutty flavor came out more, but there was a little bit more of an artificial taste that comes out. Overall not a terrible beer, but definitely needs some work.

Gold Medal Winner World Beer Cup Brown Porter Category! Ok, sold...let's learn more and find out for myself!

To Note - the specimen here is labeled 5.5%, not 6% as described on BA. Just stating the facts...

Appearance - Dark brown, almost black with a reddish tint in both the 12oz Tulip and Guinness Perfect Pint Glass I Poured both bombers in. Head is 2" from a simi-aggressive pour, solid retention and lacing throughout each sip.

S - Pretty damn aromatic of roasted malt, Straight up Coffee, semi-sweet bitter chocolate, and a nuttiness one would look for in a fantastic Brown Ale.

T - Follows Smell. Nutty brown, followed by dark roasted Porter flavors of dry coffee and chocolate. Nuttiness and Coffee dominate for the most part. Follows the description of a "Brown-Porter" to a T. Equal parts...Well done. If you're a fan of both styles...BUY THIS BEER.

M - At 5.5%, you cant ask for much more. Nice dry finish making this sessionable and drinkable. It's NOT THIN for the ABV my friends...it's just right and lively carbonation. Finishes nice and dry as I mentioned, begging for more sipping. Easy drinking beer.

O - Brown/Porter hybrid knocked out of the park for the style IMHO!!!. Equal high quality parts both. Big on nose and palate while being a easy beer to session. Well Done Mammoth!!! Not my favorite beer from them, but for the style...this is possibly their best offering. Again Mammoth, BRAVO!

look: 3.5 | smell: 4.5 | taste: 4 | feel: 4 | overall: 4

Appearance - Pours a deep, dark brown with a reddish hue. Head is light tan and about a finger width thick, average retention and leaves behind a spotty lace.

Smell - Strong aromas of dark roasted malt, giving the nose a wonderful bouquet of chocolate, coffee and nutty goodness.

Taste - Follows the nose. Starts with a healthy roasted nut flavor, then notes of chocolate come into play. A light coffee roast character comes in around midtaste and follows through into the finish. Hints of floral hop keep this from being too malty.

Mouthfeel - Medium to full bodied with a nice, lively carbonation. Finishes slightly on the dry side of things. Smooth. An easy drinker.

Overall - Beautiul Brown / Porter hybrid. Flavorful while easy on the palate. Sessionable. A certain future buy.

I'm confused: Is this a brown or a porter? As a porter, it's remarkably thin but as a brown it's not so bad, though maybe creamier than a typical one. The nuttiness is there, but not doubly so. Rogue hazelnut brown delivers exactly on its nutty name, this one not so much. A stronger nut flavor would take this to the next level. As it is, I like it, but it's far from a favorite.

Thanks to Morgan for this one!

A: Pours a deep brown color with a nice 1.5 finger off-white head. Nice retention leaving behind a pretty thick cap on top. Nice lacing.

A: Some toffee and caramel, roast malt and nuts. There is a little bit of chocolate as well.

T: Mostly roasted malt with some cocoa.Very light nutty flavor, much lighter than the aroma led on. Some faint piney hops as well.

M: Light to medium bodied, a little thinner than most porters.

O: A solid beer, hard to say if it is a kicked up brown or a porter, but either way it was good.
