Notes: Named with our atom-colliding scientific neighbor in mind, this Oktoberfest-style lager is oak-aged, providing added layers of depth to the signature flavors of roasted malt, caramel and toffee found in marzen style beers. But a beer this exceptional shouldn’t be limited to just Oktoberfest. Raise a glass, stein or boot to Augustfest, Septemberfest and beyond!

Included in a Two Brothers variety case from Costco. Poured into a standard pint glass to show a very nice orange amber clear beer and slight white head. Smell was subdued but nice malt & caramel notes gave good anticipation for the first taste. Did not disappoint! I have been trying a lot of Oktoberfests already this year and this one tasted good enough to deserve a mention here. This beer is reportedly oak-aged. Not sure if this is a common practice for the style but it provided depth and a lasting impression that other Marzens lack, imo. Looking forward to enjoying the remaining bottles & may purchase more.

From the 12 oz bottle in a snifter. This solid Oktoberfest
pours a luminous red tinged amber color with a very nice head
of white foam that settles to a thick ring, subtle swirling pool, and
sports some nice light lacing. Nose of subtle caramel malts, subtle
herbal hops, and a touch of breaded malts....very subdued. Flavors
surpass the nose nicely with a faint oak touched caramel malt dashed with
nice herbal hops and a light note of breaded malts. Very nice mouth feel;
medium body, smooth as can be and highly quaff-able, medium light
carbonation gives some nice lift. and a balanced malt touched finish
to the almost spicy hops.

An excellent fest brew from a solid brewery!

As a huge fan of Two Brothers I look forward to this beer every year. This year's version came in at a 7.0% alcohol content and an IBU of 23. If you are a fan of brown or amber ales then this marzen will be a great experience.

I don't have a fancy beer palate and I am not generally a beer lover but I love this beer. It's has a clean, non-bitter but full-bodied, mildly sweet flavor with a good kick at 7.7% alcohol for 12 oz. One beer is all I need to relax and chill out after a hard day's work. It's seasonal so I'm really sad that I'll have to wait until next Autumn to get this again. I'd love any recommendations of something similar.

12oz bottle, Fresh By 12.31.18 stamped on the label, poured into a 14oz snifter glass.

The beer pours a medium amber color, dark copper hues, fairly clear with a fizzy bone colored head, hardly half a finger tall that has no retention and yields no lacing. The aroma is pleasant, strong caramel and amber malts, a bit nutty with light spice, a touch of oak and some piney hop. The flavors echo the nose, strong amber malts, light oak, a bit of piney and earthy noble hop character with some spice and nuttiness. The mouthfeel is fine, coating and lively medium body, nice crisp and bubbly texture with an easy but dry finish, a bit weak though.

Verdict: A decent enough Märzen from Two Brothers. Balanced, hearty and crisp, good for the Autumn season.

Very good Oktoberfest brew to kick off the autumn! Poured into a 12oz chilled glass. Deep copper with minimal head which dissipated quickly. Mouth feel full and malty! Notes of brown sugar and cinnamon at the end. Will have again if available.

look: 2.5 | smell: 3.75 | taste: 4.5 | feel: 4.25 | overall: 4

Pours a clear copper color. 1/3 inch head of an off-white color. Decent retention and slight lacing. Smells of sweet malt, caramel malt, slight pale malt, slight yeast, and a hint of hop. Fits the style of a Marzen / Oktoberfest. Mouth feel is smooth and clean, with an average carbonation level. Tastes of sweet malt, caramel malt, slight pale malt, slight yeast, hint of wood, hint of alcohol, and a hint of hop. Overall, weak appearance, but good feel, body, and blend.

Pours a clear, amber color with a tight, white head that leaves little to no lacing.

Smells of oak and toasted malt.

Tastes of the sweet, toasted malts backed by the oak and a touch of hops. Malts lead off with sticky, sweet caramel and toasted bread. Brown sugar and a bit of nuttiness add next. Vanilla and woody oak notes come towards the middle before some earthy and herbal hops. Finishes fairly clean with a bit of lingering caramel.

Mouthfeel is medium with a smooth amount of carbonation.

Overall, this is a nicely done Oktoberfest

12oz bottle bb 12/19/17 poured into a.5L krug at fridge temp 7.7% ABV 22.6 IBU. The beer pours bright copper in color and an aggressive pour offers about one inch of khaki head. The head subsides quickly to a light ring around the mug and some paper thin film islands. The aroma is semisweet toasted bread. There may be a hint of alcohol in the nose as well. The taste is full with oaky notes front to back along with burnt sugar, caramel and a bit of booze. Mouthfeel is medium plus bodied, moderately carbonated, and moderately dry in finish. There is no perceived bitterness nor any cloying or overly sweet tastes. Overall, very good just for being unique. With a touch less booze and a drier finish, this beer could be really special. It's worth a try for fans of Oktoberfest beers and straight oak aged beers.

3.54/5  rDev -6.1%
look: 3.75 | smell: 3.5 | taste: 3.5 | feel: 3.75 | overall: 3.5

Pours a transparent copper color with a modest cap of off-white foam that soon dissipates. Aroma smells of a blend of caramel, butterscotch and toffee, along with hints of cherry, peat, and barrel.

The taste features a bite of peppery hops up front along with the aforementioned caramel, bread, and some apple peel--pretty much what you'd expect from an Oktoberfest, though perhaps slightly more aggressive than usual. The barrel is fairly subdued on the palate, lending a touch of wood to the middle and back. Alcohol is more present than I'd prefer toward the finish, which is uncharacteristic for the style. Medium body and carbonation make for a vibrant, creamy mouthfeel that works well.

Overall, this isn't the most delicate of Oktoberfests, but if you're in the mood for something with more gusto, this may be just what the doctor ordered.

Atom smasher Oak aged oktoberfest style lager
L: light orange brown on the light side for the style with a head that dissipates to a small foamy ring.
S: Not a whole lot going on here but oak and grain are present overall muted.
T: Oak think chardonnay followed by a lightly malty sweet roasted gain flavor just enough hops for a clean clean finish.
F: Medium fullness with average carbonation nothing really stands out here
O: This is an OK Marzen with a very subtle twist thanks to the oak. So for me it is average, I honestly rather have a plain marzen. But if oak is your thing give it a try.

So, one of the reasons that I love autumn beers is the malt-forward lagers. This one meets the needs. It is a rust brown color...not much of a head...clear and attractive. The smell is malty and the taste is intense....nice. Full in body, medium malt, a bit of grain, and sweetish. Satisfying.

12oz bottle. Poured out a clear, golden orange color with a small, tan head of foam. It smelled of caramel, toffee and sweet bread. Nice roasted malt and toasted caramel taste with a snappy bitter bite.

No, its not a good example of a traditional marzen, but its a unique take and the oak aging adds an interesting mellowing to the beer that is enjoyable.

Look: Copper in color, no head retention.

Smell: Caramel malts and charred oak with subtle hops floating around in the background.

Taste: Toasted caramel malts with a certain nuttiness. Very lightly hopped.

Feel: Slick, and relatively big-bodied for a marzen, which I find a good thing.

Overall: Very good stuff. I'd try again.

Slightly better than an average, if excluding the Bavarians. Of the 25 American O-fests I've Had, Atom Smasher is in the middle third. While I've probably had Atom Smasher three years in a row, it could improve by having hops that let the sweetness finish stronger. As is, this O-fest finishes too dry.

It is good of Two Brothers to make the effort to age this in oak, but milder hops in the boil will give the sweet malts a chance in a season that is, frankly, sweet. In the harvest, farmers get paid.

Ruby-amber body, fizzy tan head. Smells of light malt, toasted grain, faint fruit esters. Taste is similar; warm malt, some light grain, toast, the fruitiness could be described as a touch of white grape juice. No trace of wood flavor. Kinda smooth body, probably aided by the oak aging, but only light-moderate in heaviness.
Happy to see the oak in a very diminished role. The base beer flavor remained light and appropriate but the feel felt smooth. Happily surprised.

S - sweet toffee and malty. vanilla and oakiness come next. herbal hops. very interesting but also somewhat subdued. focus seems to be on the vanilla. 3.5/5

T - malty and toffee up front followed by vanilla and then oaky woodiness and somewhat boozy on the back end. vanilla finish. 3.5/5

M - lighter than expected. light to medium body. leaves mouth wet with no carbonation burn. 4/5

A: The beer is clear coppery amber in color and has a light amount of visible carbonation. It poured with a finger high beige colored head that died down, leaving a collar around the edge, a thin layer of bubbles on the surface, and some lacing down the sides of the glass.
S: Light aromas of toasted malts and candi sugar-like sweetness are present in the nose.
T: The taste is similar to the smell and has sweet flavors of toasted malts along with some notes of vanilla from the oak barrel aging. Some hints of fruity yeast are also perceptible. Some of the sweetness begins to dissipate as the beer warms up.
M: It feels just about medium-bodied and a little smooth on the palate with a moderate amount of carbonation.
O: This beer is rather malty, but the sweetness and vanilla flavors imparted by the oak barrel aging help to balance things off a little.

Poured into a perfect pint.

3.5 A: Clear light orange color. Two fingers of frothy/creamy beige head. Retention is about average and lots of spotty lacing is left.

5.0 S: This smells absolutely wonderful. Toasted malts, layers of caramel, and that lager yeast twang. Oak adds a nice layer of complexity with vanilla contributions. This is whatever the olfactory version of "smooth" is. It's just such a pleasant, subtle nose.

4.5 T: The taste can't live up to the nose, but that's okay since it's still delicious. Caramel and toasted malts, subtle vanilla, and a light metallic lager yeast flavor. Everything is right where it should be.

4.75 M: Medium body. Good moderate carbonation. Silky smooth with a pleasant creaminess. Near perfect here.

5.0 D: The best octoberfest beer I've had this season. It may not have bold flavors or a ton of complexity, but it's so subtly well done, that it's a near perfect beer.

Biggest dissapoimtment of any Oktoberfest I've had. I love barrel aged beers as well so was excited because this was "oaked".

Sadly this here has zero oak that comes through and furthermore barely even tastes like a marzen. Drinks like a thin bodied bock.
