Hey it says brown on the label, but its a porter on BA! Muh knowledge.

Pours a rich brown color, this ain't a Newcastle thin light brown, its sturdy and hey I'll give BA something, it does look porterish with its heft and lighter brown head 3/5" down. Does have that lightly nutty aroma, reminds me of that coffee with nuts in it.

Taste is better than your average brown ale, but I just don't see the heavy malt roasting indicative of a porter here, it has more of a deft hand, lighter roast, but more malt if you will. So I'm still saying brown ale. Hints of chocolate and caramel to it. But just not that bitterness and roast depth of a porter, much less an American one. The hopping is minimal unlike an American porter.

I think if you like brown ales, you should go for it. I wouldn't mind having a bottle or two on hand for those I party with who don't like sour or hoppy, but also think a super roasted sludge imperial stout is too intimidating.

Dark brown with white foam.

Light roast coffee.

Blind I would've guessed a touch of lactose. Almost no bite, not much sticks out. Touch of cocoa powder, roasted malt. Beer without flaws but nothing particularly exciting.

Pretty smooth.

Having this beer during happy hour at the hotel bar on my last evening on vacation in Indian Wells, CA before my dad and I return home to Cleveland tomorrow. Poured out of a 12 oz bottle into a pint glass, this beer pours a very sark, almost black color with a tan head that’s about 2/3 of an inch when first poured. Head settles to a medium sized ring lining the inside of the glass along with a pretty solid film layer of surface foam that’s accompanied by some nice lacing. Aromas of roasted malts and nuttiness that has some caramel sweetness along with hints of chocolate. Has a roasted malt and nut flavor that’s folowes by some notes of caramel and chocolate sweetness along with just a hint of black coffee bitterness. The flavor profile is rounded out with a hint of earthy hop bitterness. A very well balanced flavor profile. Has a fairly crisp, just slightly prickly, smooth, lifjtbto medium bodied mouthfeel with light to slightly moderate carbonation. One of the lighter body porters I’ve certainly ever had. And that works well here I feel. Has a clean finish and mildly smooth aftertaste. Glad I got the chance to try this. Recommended by me if you get the chance to have it.

Nice dark brown with a dark reddish hue and an off white head. Smells of rich malts. Taste has some burnt nut in the malts along with some slight chocolate and hints of nuts and fruits. Mouthfeel is not bad at all. Not a bad porter at all. Nice winter brew. Prost!

March 19th, 2015 - It's porter night with Mammoth's Brewing Double Nut. I wish I was drinking this next to a fireplace at a ski chalet, but no so luck. Appreciably brown in the color, it has a thinner, velvety head, and a tangy note in the nose, the lactic tang resounding with a yogurt funk. There's also some apple pie in the aroma, with spices and sweetness. Espresso leads the way in the flavor on the foam, with a good malty bill underneath. The lighter body is excellent too, but I keep coming back to the foam too. While the flavor is unremarkable, that body is epic.

F: Medium body, below average carbonation, syrupy.

O: A decent enough Porter/Brown but could be better.

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.

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.

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.

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.

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.

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.

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

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.

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.
