O'Reilly Irish Stout...on tap at the Sly Fox Phoenixsville Location....

Appearance-nice looking nitro pour, very carbonated, jet black color in the pint glass, the head settles very nicely.

Smell-dry toasted malt, light touch of coffee, mild alcohol.

Taste/Mouthfeel-light mouthfeel, malt mixed with coffee, slight hops pull through but the malt buries it, exceptionally smooth and consistent. Finishes almost clean but with a touch of malt.

Drinkability-easiest drinking ever.

Overall-dynamite Irish Stout, great sessioner, obviously knocks the big boys out of the park. Excellent job

a: Very pretty nitro pour. Thick, cascading, creamy looking head atop a dark brown body.

s: Faint roast and a hint of dark fruit.

t: Hmmm... maybe a dirty tap line? Bitter, almost flavorless roast and a little something sour in the backround.

m: Nice, creamy nitro body.

d: I had high hopes for this, I'll definitely try it again elsewhere if I see it.

O'Reilly's Irish Stout by Sly Fox is pretty much all one would ask for in a dry Irish Dry Stout. This beer, served on nitrogen, carefully poured at Local 44, is pitch black with a fluffy, 2.5 inches of beige meringue foam. The beer has just a faint wisp of chalky roasted grain. This beer tastes almost perfect. It is plenty dry with flavorful espresso and dark chocolate roasted flavors. The hop bitterness strong and a bit surprising considering the mellow hop flavors in Guiness, but it works well with the creamy, silky mouthfeel, accentuating the dryness of the beer. This is a pleasure to drink and at 3.6%, it is very easy to keep going with it all night long. The only thing was that the roasted grain and bitterness from hops made this just a bit too astringent, but overall, fantastic.

Looks like a nitro-tap stout with a little bit of cascading bubbles and good lacing.

Smell is a bit muted but nice with dark roasted coffee.

Taste is predominantly dark roasted coffee. Hints of dark chocolate towards the back end with even some earthy hops in the finish.

M - Light body, delicate carbonation, finishes clean with even some lingering bitterness from dark roasted coffee and hops. Never feels watery.

D - I would definitely get this again. Packs a nice punch of taste and bitterness in the finish which keeps it interesting.

I've had this this several times now - each time on nitro - and each time it's a dependably decent brew. Love the nitro and it's ultra-creamy pour - cascade action! - leaves an inch thick compact velvety khaki-colored head atop of the pitch blackness below. The scum left behind is immaculate. Being served via nitro, the aroma can range from quite muted to a soft roasted bitter - not a wide spectrum - but, for what style it is, it suggests something weightier, or more substantial, in density and concentration of flavor and feel than say Guinness Draught (which essentially is dirty water). Lovely smooth, more bitter than roasty, taste. Real creamy. Actually hangs on the palate nicely. I've had it with a more relaxed degree of nitro and the flavors really blossom. Hints of industrial coffee and some vague nuttiness. They really nailed the style as I sometimes confuse it for Murphy's (though it's still better).

On the nitro tap at the Old Eagle Tavern on 11/10. Reviewed from notes.

Pours a chocolate milk brown with a fizzy, off-white head. Gets darker in color as the cascade fades, leaving behind a creamy lacing that sticks around for a bit.

Aroma packs in melted chocolate, medium roast coffee, licorice and toffee. It's a nice mix of sugary and bitter and it got me excited for my first sip.

Stout itself is creamy as hell with a nice coffee bean bite in the finish and mild smoke notes lingering in the back. Milk chocolate takes center stage here and one could say that this is reminiscent of a drier and subtler Young's Double Chocolate. Very tasty!

The smoothness on display is profound and this ale manages to nicely balance its two elements (roasted notes and sweet notes). Consistency is similar to a cold glass of milk, but without that annoying coating on the back of your throat.

This is definitely my favorite American-made Irish Dry Stout and the flavor profile and low ABV are perfect for an all-day session.

Sly Fox O'Reilly's Irish Stout

on tap from McGillin's in Philadelphia, PA

Appearance: Dark brown, medium head, and lots of lacing.

Smell: Dark chocolate, coffee, and slight smoke.

Taste: Smoke, coffee, and slight dark chocolate.

Roasted smokiness with some chocolaty coffee. Not bad.

O'Reillys Irish Stout on Nitro tap. Pours a dark blackish brown with a solid fingers worth of tan foam. Wall of lace.

Smells of bready and roasted malts, but not a very strong smelling beer.

Starts out with a creamy feel, followed by an ever so faint roasted malt note. Lightly bitter, but not a lot going on.

Spritzy carbonation with a semi-smooth overall feel. Creamy.

Drinkability is decent. A nitro stout with nothing out of place, but not a whole lot stands out. A fair attempt at a Guinness imitation brand.

On nitro tap at Sly Fox Brewery (in Royersford) into a standard pint glass. Poured a with a creamy one-finger head which settled to creamy off-white coating. Lacing was abundant and lasting. Nose was some chocolate, roasted malts and coffee. Taste was dry and moderately bitter, heavy roasted malts, grain some chocolate, and burnt coffee. Mouthfeel was light, very creamy and well-carbonated. I can't remember the last time I had a beer that was 3.6% ABV but clearly you could down a few of these without damage. A decent offering but nothing I would go out of my way to have again.

Pours a deep amber, almost black in color with a creamy white head. In the aroma, a faint roasty malt. In the taste, grassy and a small dry roasty malt. A smooth and light bodied mouthfeel, with a dry, small bitter aftertaste. Quite thin, and lacking in flavor and aroma.

I had at d.b.a. in Williamsburg, Brooklyn off the tap.
A- It has a nice dark color to it, basically black. It has a big head that leaves a fair amount of lace.
S- Slight tartness to it.
T- This beer has a nice smooth vegetable (celery)) flavor to it. For a stout, it has a bit of tart chocolate taste, but very smooth once down.

Sly Fox O'Reilly's Irish Stout has a black body and a creamy, brown head that has the waterfall affect from the nitrogen.

The aroma is pretty tame: a little bit of roasted malts and some coffee flavors.

Just like the aroma, O'Relly's Irish Stout has a flavor that is subdued roasted malts and a dash of coffee. There is also a hint of hops in the form of a grapefruit flavor. This is a little bit underwhelming, but not bad.

The feel of the stout is a little bit thin despite the creaminess that the nitrogen adds.

Overall I don't love this stout, but it's not bad for a low ABV beer, but I don't love it either.

A: Black, viscous liquid with a creamy tan head that leaves a bunch of lacing. A good looking stout.

S: Malty and mildly smoky. Otherwise, nothing too extravagant here.

T: Malty and chalky with an abrupt and dry finish. If I didn't know what I had ordered, I would have thought this was a Guinness.

M: Really thick brew with a creamy mouthfeel. The funny thing is, as thick and rich as this one is, it isn't overly filling.

D: Fairly drinkable, and not as thick and one might perceive. Still, nothing overwhelming, either good or bad. Stout's aren't my favorite style, but I've tried several and have begun to appreciate them.

Pours black with huge dense undulating head that takes several minutes to settle down. Aroma is roasted, like bitter chocolate or smoke, and evident at a distance. Flavor is sharp and coffeelike, bitter roasted like an excellent campfire. Deep caramel, round nutty bitterness. Mouthfeel powerful thick and creamy. Insanely creamy.

A-jet black in color, no light comes through, a thick white head accompanies the deep black color

S-light roasted malt aroma with a hint of chocolate

T-very light in flavor, almost watered down and similar to a guiness, the taste is of light roasted malt and just a hint of coffee

M-very light body yet very smooth and low carbonation

D-it does bring some flavor and is very low in body, seeing the alcohol content just now i realize why it is so light. i guess i should give it a higher score b/c you could drink this all day and never get drunk; but personally i'd rather get drunk fast and drink something i enjoy.

Had this on tap @ the Fire in philly seeing my friends band, Action park, play....

Pours pitch black with an off white, cream colored head. Very creamy! mmm...

Its smells like the usual Irish stout. roasted malt dominating with chocolate aroma pull through in the end.

Taste is medium bodied and very creamy. Roasted malt with chocolate coffee notes.

A very solid stout! I've been in the mood for a good creamy stout and now I'm very satisfied.

Pours an opague black with some liveliness going on in the glass as tiny little bubbles struggle to get to the surface. They finally settle and makes about an inch coffee colored heading that looks oh so creamy and TASTY!!!

Smell is very light in roasted malt a bit more of a coffee and chocolate aroma pull through in the end.

Taste and Mouth is very thin but ridiculously creamy.The menu says light bodied but I will go with medium. A nice roasted maltiness kicks you in the mouth then is taken over by some chocolate notes. Carbonation is awesome the best I've had for a stout.

Drinkability maybe a bit heavier for the summer days but definetly on a nice cool and cold day. Very easy to put a few down.

Got this on tap as a special offering from the Cloverleaf Tavern.

A: Pours a dark brown - almost jet black - body with a silky, one finger tan head with very good retention and lacing.

S: A slightly bitter, dry smell with some roasted barley undertones.

T: A fairly subtle, roasted taste that finished fairly dry. Nothing overbearing or overly amazing. A slight bitterness in the aftertaste did well in contributing to the dry finish.

M: A little light, like a nice stout and very smooth on the palette. Very nice for the style.

D: A pretty good mouthfeel and taste combination makes this beer very drinkable. While the mouthfeel seemed to be almost spot on for what I was expecting, the taste could have used a little bit more robustness with the roasted notes. Overall, still a nice beer overall and worth a shot if you get the chance.

on nitro-tap at McGillin's poured into a nonic glass

deep black body....creamy off white/tan head....superb lacing

toasty malt....with touches of coffee and caramel

subtle sweetness yet still dry with some toasted malts, coffee and dark chocolate flavor...light and creamy

light creamy mouthfeel...light in alcohol

this is an all nighter for me....this is hard to come by where i'm from in NJ so when i find it when i 'm out i stick with it for most of the night...the limited availability (for me at least) along with the super low ABV help in it's drinkability

excellent Irish stout....actually prefer this over that other "well known" Irish stout

20oz pour off a nitro-tap at Teresa's. 1st time trying this which is amazing since it's all over.

A- O'Reilly holds a deep roasted brown color that borders on black, it's very close. A cascading head eventually builds a solid creamy looking cap about a inch in height. Solid sheets of thick lace stuck on the glass.

S- A nice huge focus is on the roast. This has a huge roast that is str8 off the grill. Some scents of smoke and some chocolate and coffee, maybe some bacon as well. Some faint traces of caramel while a splash of cream/vanilla comes up. A lot of malts in this I see.

T- Well, this is quite a treat as im not very big on this type of stout. This beats guinness by a long shot and the nitro blast is a good addition. Again this is dominated by a slighty smoky roast with char but is offset by some creamy appeal. Some chocolate and coffee within as well but comes out more as time goes by.

M- Incredibly smooth off of the nitro tap, this stout is fairly thin bodied but has a better feel than most in the style. Even with all the roasty taste in this you would expect this to be more rough, but that is not the case. Has a dry finish plus silky.

D- I ordered this because it has a low ABV and I was driving, so it has that going for it. While good I don't see myself having another but will get it from time to time. Having it off the nitro tap, I don't see having it any other way would suffice.

I had this on tap at the 2009 goat races at the brewpub in Phoenixville, PA. Served chilled in a willybecker.
A -Dark opaque brown, med brown at the base, thick 3/4 inch band of cream from nitrogen pour, thick lacing collects in rings

S - Roasted malt, fruity yeast scents. Light caramel notes w/ very mild hop aromas

M - A creamy textureat first followed by dark roasted almost bitter texture w/ intense roasted feel carrying through w/ a hop bitterness trailing.

T - A moderately bitter stout for the style. Taste-wise the malt is very roasted which gives the malt a bitter quality w/ a gentle caramel malt back. The nitrogen sharpens the black malt slightly w/ an increased bitterness in the taste. Very one dimensional flavor after the first pint. Not a bad tasting stout, just lacks a layered malt flavor and seems to bitter for the style.

D - I would be content w/ one since the roasted flavors and hops overpower the beer and nitrogen is not my favorite form of delivery. This is just ok in my book and compared to guiness it is a toss up personally. I think for the abv it has a lot going on.

Enjoyed a five beer sampler of 4 oz, Michelin Man style glasses, beers.

Held the same micro bubble head for about 30 minutes. Pronounced roasted aroma. Very nice.

This was my final beer. Aroma and appearance get things going very well but it's down hill from there.

Taste comes across as watery. Not nearly the flavor I was expecting based on the wonderful aroma. Easy to drink but need a little more uuuumph! One dimensional to the roasted side and continues to have a watery element to it.

Have had this numerous times on tap at the Tap and Mallet.
It's an easy pour and very silky in your mouth. Feel the head could be a bit less pronounced on this, but is still decent.

This is one of my favorite stouts. It pairs exceptionally well with food and is not obtrusive with other flavors. The lacing is great. In my opinion has overtones of coffee and nut.

On tap at the brewpub.

Pours a clear dark orange, brownish tinge, very thick light tan head forms, drops a ton of lace on its way down, settles to a very thick layer, very creamy looking, bit light in colour for a stout though. Smell is alright, grainy and sweet, some caramel, light roast and chocolate, toasty bitterness, some raisins and dark fruit, not too bad. Taste is very dry and grainy at first, caramel sweetness, toast, light roast and chocolate, oats/cereal, very dry in the finish, light on flavour but nice. Mouthfeel is light bodied with low to medium carbonation, very smooth and drinkable. Just a bit too light to be great, but a decent Irish stout.

Reviewed on 9/3/08. On tap at the Ginger Man. Pours black with a small dark tan head. Very pretty! Aroma of roasted malt and coffee. Aroma of roasted and sweet malt with a bitter hops finish. Quite dry. Watery, weak palate. Meh, not much to this one.
