Tree House Brewing Company
Massachusetts, United States
Notes: We are pleased to introduce Abstraction - an Imperial Porter brewed with the approaching cooler seasons in mind! Utilizing a sturdy base of Chocolate, Caramel, and Roasted malts and gently hopped with Warrior, Abstraction presents with flavors and aromas of chocolate syrup, fudge, and creamy coffee. It calls to mind an evening spent around the fire with friends or loved ones or a hearty meal featuring seasonal produce. At Tree House we strive to make beers that are a true joy to drink all the way through a full glass. With bold flavors created by characterful malts from the USA & Germany, a hearty mouthfeel, and a smooth and creamy finish, Abstraction adheres to that ethos beautifully. This beer should age well when kept cold in the refrigerator for 4 - 6 months and can be enjoyed throughout the coming cooler months.

Decanted from a 16 oz (473 ml) can into a pint-sized, Tree House Willi Becher glass; canned 11/10/20, code BE FRESH.
A: Pours dark brown color with a one finger, light tan head that dissipates rapidly to rim with little or no lacing.
S: Aromas of sweetened black coffee, dark chocolate and cola
T: Sweet. Flavors mirror the nose closely. Bitterness offsets the sweetness.
M: Medium bodied with low effervescence. Very easy drinking.
O: This might be my favorite example of the style. Drinks like a soda, but at 9.0% ABV, packs a wallop.

Canned 11/10/20, tasted 1/31/21. Really loved this beer, and the colorful, geometric Tree House logo on the can was gorgeous too! One of my favorite porters ever - to my palate, this strikes the perfect balance that a porter should bring to the table: richness and sweetness with some crisp and bitter roastiness to match. That dark chocolate, almost cherry flavor in the middle rides that perfect line without becoming cloyingly sweet or unpleasantly bitter. I could see TH doing some interesting things with a raspberry version of this - it seems like the perfect base for that...

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

A: Pours a near pitch black color with 2 fingers of head that fades down to a thin cap

S: Roasted malts, dark chocolate, coffee, light cocoa, caramel, and a touch of dark fruit

T: Follows the nose. Starts off with the roasted malt, dark chocolate, definitely more dark fruit than the nose let on, bitter roast coffee, and some caramel. Picks up some very light cocoa and some earthy hop notes. Finishes with lingering roast

M: Medium-full bodied with moderate carbonation

O: A very nice robust porter that is on the easier side to drink, despite the heavy malt and 9%. Quite complex in the absence of adjuncts, too. Worth a drink

Dark syrupy molasses black with a short fluffy tan head settling to a creamy but thin collar.

Roasty cacao that's nutty and semi-bitter, plus a light espresso-like tang, make up the bulk of the experience. An accent of amaretto meets a light astringency of metallic Brillo pad for a moment, before ashy cigar and tobacco develop on the swallow.

The medium body has a mild froth before finishing powder dry.

Canned on 5/20. Opened on 6/28.
Different from NEIPA, it is said that "kept cold in the refrigerator for 4 - 6 months and can be enjoyed throughout the coming cooler months."
I am not Porter /stout drinker. Ex. Milk Stout is toooo much sweet for me.
yes, Abstraction is sweet but light (Compared to other one) .
Say, like feel, heavy iced coffee+Chocolate+Cacao+Maple. Not bad.

ABV.8.8% Imperial porter.

TH has some sort of magic or a secret recipe that no other brewery has access to. No porter should taste this good. No porter should be this silky. The level of flavor is like few others beers of this style. Creamy, viscous, rich dark chocolate, perfectly roasted malt, and some espresso. This beer surpasses the concept of the style, whether it’s imperial or not. A masterpiece.

Picked-up two cans at the Tree House Brewery in Charlton for about five dollars. My forty sixth brew from these guys. Like porters, but usually stick to IPAs. This was very good. Don't sleep on TH non-IPAs.

A - Pours dark, black with red and brown highlights. Head is light tan, moderate but persistent, lacing is extensive with small bubble lines.

S - Nose is full of roasted malts, a bit of booze, a thundering chocolate undercurrent with some bread and coffee notes floating over it.

T - An explosive chocolate burst out front, with cherry and amaretto rising in the middle, and a sharp bitter spike in the finish, coffee and acidity.

M - The weight is heavy for a porter - I’ve had stouts with less density.

O - Delicious and deep, a real treat.

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

A- Can into a snifter with a pitch black body and a one finger, very thick and creamy cap. The head has a dark brown, almost burnt toffee hue with great retention. Large webs of thick lacing coat much of the glass.

S- Chocolate, roasted barley and coffee come to mind. Fudgey and rich with a massive contribution from the browned to roasted grains. Toasted nuts, molasses, licorice, milk chocolate and caramel.

T- Very roasty with the bitter dark grains, chocolate and sweet caramel dominating the beer's flavor profile. Drinks rich even for the 8.8% with support from toasted nutty, fudge, licorice, molasses, toffee and espresso notes. The balance of flavor is a bit lacking to be honest as the dark chocolate kind of sticks out above the rest and the beer's flavor profile fails to find much balance. There is also a raw grainy quality to the flavor here.

MF- Thick and very rich brew on the taste buds. The carbonation is at a medium level and it ends with a roasty bitterness.

Bold and powerful roasted grains but in the end the dark chocolate and bitter roasted raw grain flavor kind of disrupts the balance of it all.

16oz can into Night Shift stemware.

Nose is chocolate, roasted malt, cocoa powder and iced coffee. Rich and robust. Beer opens sweet and nutty. Hints of coffee, molasses, chocolate and cocoa powder. Brown sugar and hazelnut in the middle. Finishes fudge, coca cola, fudge and chocolate. Solid. Medium bodied with low carbonation. Smooth and rich on the palate and velvety going down. Messy finish with a lingering aftertaste. Impressively robust.

Solid all the way around and a great base beer for accepting their unique flavor additions.

A: Poured from the can into a tumbler pint glass. Body is black with a thin tan head on top.

S: Chocolate, roasted barley malt and molasses.

T: Very chocolatey - almost fudge-like, actually. Molasses. Roasted malt. Hint of smoke.

M: Full-bodied. Carbonation is soft and fine.

O: Very good. Drinks more like an American Stout than a Porter.

Serving: Can
Canned: Apr-3-2019 (Consumed Apr-30)

It pours thick and black as pitch with a inch+ of short-live, airy brown head.  Meh retention; speckled lacing. (3.75)

Smooth, nutty, mild coffee, lightly smokey. (4.25)

Lightly sweetened espresso, hint of smoky sweetness, rusty hard water. (4.25)

Fairly thin, well-hidden alcohol, moderate carbonation, lingering roasty finish. (4)

A tasty stout with a very nice coffee character.
It looks nice in the glass but doesn't benefit from great retention. The aroma is great. Soft coffee aroma that smells nutty and slightly sweet and just support from the malt. The flavor follows suit with nutty, black coffee flavors, tobacco and a touch of sweetness. It is fairly thin for the size, but is better served by that than by being cloying. Drinkable and generally enjoyable. I'd have it again. (4.25)

Sampling a cellar temp 16 oz can of a beer that was given to me by @schuee. Thanks!
the beer pours a dark chocolate color with a fluffy beige head of 1.5 com foaming up. The bubbles fades slowly leaving some craters on the surface of the spongey head.
The aroma is pretty bold on the pour with roasted malt notes and dark chocolate filling the air at my table. No need to dig in to get these scents. A few deeper whiffs reveal more of the same, with just a little bit of charred wood coming through too. No hops on this one.
First sip reveals an average body with fine and tingly carbonation and smooth texture. Very easy drinking brew.
Flavor is what I expect from the nose, some dark chocolate and roasted malt dominate, with just a little bit of sweeter milk chocolate in the middle and then back to all roast for the swallow. Again, no hops here and the 8.8% is very well hidden to make for a bit of a dangerous brew.
I like this imperial porter and find it sneakily drinkable, it doesnt blow me away but is very solid.

dark brown, almost black pour. smells of chocolate, little bit of caramel and slight hops. tastes is similar with some nice hop bite on the back end. feel is quite impressive. just as full as any of their stouts and not as much carbonation as all their milk stouts. very solid porter.

Smooth with complex flavors with taste of richness and mouthfeel. Was weak on head retention and had nice aroma of the chocolate and coffee. Ordinarily I am not a huge fan of stouts and porters but with the coffee and chocolate I would not mind always having this beer in my fridge.

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

Appearance: Pours the color of used motor oil with a thin beige cap; spotty lacing all around

Smell: Chocolate and caramel with undertones of roast

Taste: Chocolate and caramel with building roast tones; while there is plenty of roast, after the swallow, the sweeter chocolate and caramel wind up on top

Mouthfeel: Medium to full body with moderate carbonation

Overall: Tree House was going for a fudge brownie and that is pretty close to what they got

Thanks, PhineasMcClintock, for the opportunity

Can to sniffer. Tree house/Kane stout tasting with DC.

Jet black color. Healthy light brown head. Waves of lacing within the head. Very pretty.

AROMA: roasty malts. Wood, char, touch of black licorice.

TASTE: here's where those promised fudge brownies kick in. Bittersweet and fudgy. Wood, tar,

FEEL: Silky smooth. A little thin, but this is a porter, not a stout, so fair enough.

Thanks to jlindros for sending this beer and a bunch of others. One of my faves of the pack, unheralded, unheard of by me, but thoroughly enjoyable and an elite tier porter banger. Pours a dark brown with a tan head in the 3/5" range. Looks good. Aroma of chocolate malt, wave after wave, simple, brown, good.

Taste, wow, so enjoyable. Its a smooth non adjunct porter, while there is plenty of roasted malt, it never comes off heavy, viscous, sweet nor bitter. So much unsweetened caramel and chocolate effect simply from malt usage, love it. Just smooth is the word that keeps popping up. Total treat to drink all the way through. Man if you're ever feeling like ragging on adjunct laden porters/stouts, this is the beer at the top of your list to be a great counterpoint to much of that noise. The real crazy thing is how good it was at covering the alcohol without relying on any of those bag of tricks.

While all the hoppy Treehouse beers are definitely very good, this is the most unique very good one I thought.

Picked up three cans of this at the brewery.

A - Poured in to my Duvel tulip a nice dark brown almost black with a one finger mocha head that fades slowly to leave a thin, creamy blanket.

S - Aromas of some light chocolate, dark bakers chocolate, big acrid roast coffee to the point that it smells over roasted. Almost metallic. Little bit of charred aroma as well.

T - Taste is similar to the nose. Decent amount of bakers chocolate, almost to the point of being grainy. That metallic note is gone, but the acrid burnt roast is much more intense. The coffee notes are a bit nutty, flashes of overcooked caramel. Tastes like the burnt end of a brownie washed down with an over roasted cold brew.

M - Mouthfeel is nicely carbonated, creamy, silky, alcohol hidden nicely.

O - Overall this beer, while looking and feeling great, suffered from I think over roasted malts. It's a really nice base beer but there are just tons of acrid, astringent over roasted burnt flavours.

Pours opaque, dark brown n color with 1/2 inch head. Taste is deep chocolate, caramel, and cocoa. Medium-heavy bodied, moderate carbonation, sweet and roasty. Not always a fan of Tree House's maltier offerings, but this is very very good. I think I like it due to its lighter body. Very much a porter as opposed to a stout. Will look for this again.

This beer is great. It's thick as balls and has more chocolate flavor than most beers with chocolate additives.

Tree House doesn't need lactose or adjuncts to make a full bodied dark beer. This is an explosion of chocolate all over my mouth. So good.

From a 16oz can, dated 09/11/18. 'Backwards down the numberline' - again, no clue what that might mean. Served in a tulip.

Pours a deep walnut-black, impervious to light once in the glass, with about a finger of soft, tight mocha foam. No retention or lacing to speak of, just a feeble little collar.

Smells of espresso powder and bittersweet chocolate. Maybe a little fudgy on second sniff.

Taste follows the nose precisely, right down to the first impression of bittersweet chocolate and then, on second thought, maybe fudginess. Straddles the line between sweet and dry, finally coming down dry. Minor notes of chicory and cherry, semi-harsh espresso bitterness lingers on the palate for days.

Feel is smooth and dry, medium-light bodied and brightly carbonated, in fact maybe a smidge too brightly carbonated.

Overall, yes, it's Tree House but, yes, it's a rather ordinary... porter? So they say. Except that the chocolate and espresso flavours are just particularly fine.

L - molasses and motor oil coming out of the can. Laminar to the max. Just a smidge of dark brown roasty lacing.

S - very strong aromas shooting out of the glass. Dark fruits a la dates and plums accent a backdrop of burnt coffee roast and dark chocolate cake.

T - what's this? No lactose in MY dark Tree House beer? It is chocolatey to the max, but aggressively balanced by dry, bitter coffee roast. Thick fudgy sweetness and the tiniest touch of booze warms the bones. Earthy, grassy bittersweet dark chocolate dominates. Crisp and fresh.

F - velvety smooth, but maybe a hair on the light side, which is surprising given its ABV. Feels like a stout (don't hurt me).

O - nice to see a more traditional stout- uh- UH- porter (yes, a PORTER) from Tree House. Like a double Catharsis, this cranks up the roast but still retains that chocolately pawnch.

Canned 9/11
Pours a thick black dark foamy 1+ finger head that fades at a med to slower pace, a fair soapy lacing and pitch black thick beer

Nose brings burnt milk and cooked lactose sugars, caramel and creme brulee but not too sweet, roasted malts, with a touch of cocoa and over roasted coffee, little cocoa fudge brownie and hint of nougat, charred cocoa

Taste brings more roasted everything, roasted malts, roasted coffee, burnt milk and lactose sugars, charred fudge brownie and more super dark cocoa, dark chocolate chips, a little sweet caramel burnt flan condensed milk, burnt mocha java, bitter roast and some acrid astringent bitterness late, sticky sweet finish with more burnt acrid coffee milk and roasted cocoa

Mouth is fuller bod, rich creamy thick, decent carb for the style although a bit light, not bad on the alcohol either

Overall eh, a bit too much acrid burnt roast etc, maybe some aging will calm that down, so I'll have to sit on the other two cans for a while. Nice base beer if not for the acrid astringent over roasted burnt flavors.
