This beer pours a pale amber with decent head. The aroma features sweet pine, rich floral, rich caramel malts, burnt orange, resin, and plant matter. The flavor is a good blend of sweet and bitter, with burnt orange peel, mango, sweet pine and resin, cannabis, grass clippings, caramel, and dandelion. The mouthfeel us fairly full with pleasant foamy carbonation. Overall a quite tasty old school west coast IPA.

Clear orange hue.

Bright white head; strong lace.

Malt & dull mango nose.

Medium thick mouthfeel.

Malts & booze cover the fruit; slight bitter finish. Despite all that, this is smooth & drinkable.

Well any bottle with a hop cone in it gets a minor boost in the appearance category, so cool. Other than that, usual copper color, small white head. The aroma would have been better if it was more diverse. Pretty much that standard bitter grapefruit thing going on.

Taste comes around, bitter citrus and grapefruit, malt bill restrained, a little sticky. Best thing it does is hide substantial alcohol.

Exceptional IIPA - was surprised with the whole hop cone even after reading the disclaimer. I've had this on tap and growlers before and loved this beer! I think the hop come is a funky marketing scheme but I like it if it's consumed fresh! Love O'so!!!

Look - have to give it a good review when it has a hop in it. Besides for that it also has a great head and a lazy Amber color.
Smell - piney citrus hop smell with a malt backbone.
Taste - bitter piney slight grapefruit taste and a toffee malt backbone.
Feel - medium body with quite a bit of carbonation and a slight bite.
Overall - pretty good beer, not worth the money. Really well balance!

Wow, each time I have this one it seems to grow on me more. The hop cone in the bottle seems to add a fresh dry hopped flavor that has depth (green and herbal notes) and does not linger bitter. This beer is well balanced in my opinion. Very smooth and drinkable. Yeah it may be a bit sweet for a true hop- head but it doesn't get cloying for me . I hope I can get more of this from Wisconsin. It is not sold in Michigan. Thanks to my hunting buddy from Wisconsin for trading with me and putting this in the box.

12oz bottle. No bottling date. Poured into an O'so snifter 11/10/2014. And yes, there is an actual hop cone in the bottle..

A- Murky, hazy mud-brown-copper body, one finger offwhite head, good retention- drops into a thick collar, some lacing. The muddy nature of the beer kind of throws me off here. And the hop cone... yeah. [3.25]

S- Sweet toffee, a bit of grapefruit, lots of resinous pine. Certainly nothing complicated, but it smells fairly sweet. [3.25]

F- Toffee, pine, caramel, a bit of grapefruit. One of the more slick, resinous IPAs I've had. That's about it. [3.5]

M- Medium bodied, resinous, sticky with a piney, herbal finish that has a bit of an alcohol burn to it. [3.5]

O- Decent DIPA, nothing too surprising or tasty aside from the hop cone. Malt heavy, pine heavy. The hop cone is kind of a novelty, but perhaps it adds a bit to the resin-forward nature of the beer. [3.5]

Final score: 3.44

Pours murky golden amber with a thick, foamy head. Lacing sticks. Two hop cones float it in. The floating, soggy hop cones detract from the appearance, in my opinion.

The smell is of pine and caramel. Robust.

The taste is piney, spicy, citric. Caramel backing balances it. Some alcohol shows in the potent finish.

On the thin side for an imperial, but it holds together well enough for a long, hoppy finish.

Overall, a good Imperial IPA.

Sorry Ralph, I couldn't wait any longer. Beer has a carmel hint with bitter hoppy after taste. The hop cone is a unique touch - adds to the bitterness.

(See update, below.) From a bottle into a tulip glass, it pours a hazy amber, w/ a thin white head.

A reserved aroma. Sweet and grainy, rye bread, molasses. Pine needles, nuts, black pepper, and leather, all overlaying the sweetness. Plus some citrus--lime, actually.

Sweet and bready up front. Some will call this cloying; I love it. It's an adamant sweetness that tugs against the grassy hops all the way through this long, complex ride through flavor land. Brown sugar and biscuit, absolutely, plus some diacetyl that makes for a butterscotch candy delight. Wood and grass shake hands with the sweet notes and introduce the hop bitterness. The sweetness becomes tropical fruit in the presence of the hops, mango, I'd say. Finishes dry and salty, a long finish of simple syrup and oak aging mellowness. The alcohol says hello before it's done. And, yet, there's something not quite great about this flavor. Too busy, perhaps? Still, totally impressive.

Wonderful in the mouth, viscous, syrupy, creamy, despite the moderate, cleansing carbonation. Mouthfeel is the raison d'etre, here.

Massively complex. So many star turns for the various profiles. Will definitely divide audiences due to its uncompromising flavors.
UPDATE: 11/9/2014
After 11 months in the cellar, it's significantly degraded and oxydized. The color definitely shows the damage. The aroma even more than the color.

However, it's still remarkably delish. Wife loves it. The oxidation actually enhances it's flavor profile. IIt reminds me of a sauterne, or of an over-the-hill, oakey chardonnay. The mouthfeel is still totally awesome.

I'm thinking, though, that it's only got a few more months in it. I better drink the other seven bottles in my cellar.

NOTE: Gotta drink the other bottles in your cellar before they degrade too far.

On tap @ Balzac wine bar Brady Street Milwaukee East Side @ 6 a pint pour. Date night but did not feel like wine- to bartender "where is O' SO? Bartender- not sure but great beer our staff go to beer. First view nice honey color and clear but little head- maybe soapy glass. Smell is a stand up and notice, Sculpinesque or Headhunter? Wow and taste is extremely hop forward floral, bitter but with a balanced long clean finish. Great, memorable beer sure to put Plover, WI on the beer map. Maybe best IPA in the whole state and holds court with Headhunter, Selinsgrove, or Perpetual in my current home state of PA. Discount Liquor you better have some in stock for me. Try it if you can find it, particularly on tap and Kudos to Balzac as one of the best wine bars in Milwaukee having such a great beer and overall thoughtful beer list. A+.

12 FL OZ bottle
Served in a tulip glass

A - It is a peach/amber color with golden highlights. It is capped with a couple inches of off-white head. The bottle contained a hop cone. I guess that is better than a serrano pepper. I'm looking at you Cave Creek Chili beer.

S - It has a sweet birthday cake-like smell. When I poured it I got some grapefruit, but the smell is a lot sweeter in the glass.

T - The initial taste is sweet. Then the bitterness kicks in at the end. The bitterness is intense enough to wipe out any trace of the sweetness up front. It leaves a lingering, bitter aftertaste.

M - Moderate

O - I do not like the sweet smell or taste up front. Thank goodness for the bitter aftertaste to help me forget the sweetness.

Really enjoyed this one based on a recommendation from a friend. All of the other reviews are spot-on.

a) cloudy with minimal light coming through

s) wonderful smell -

t) sweet at the onset and a bit bitter/heavier towards the end

m) went in smooth over the palate and seemed to get more robust as it headed towards my gullet

o) loved it - with my stash of Hopslam long gone and no nearby availability of Myrcenary, this is a diamond in the rough.

Each bottle of Lupulin Maximus has a hop cone added to the bottle so each pour brings the cone to the neck and your beer basically filters through on the way from bottle to glass. Gimmicky? Absolutely, but fun and unique as well.

A silky but dirty white head sits atop the tarnished copper body, rising to a solid cap and quickly falling to a thick ring that's constantly replenished by creeping carbonation. The body glows pumpkin orange when backlit and the silky head leaves behind drink lines.

There's a robust, sweet hop profile dripping with brown sugared grapefruit, orange marmalade, wildflower honey, and candied citrus peel. Floral characteristics separate from the honey and dank resinous supplement the citrus qualities. The malt base is also pretty substantial bordering on red ale. Lightly toasted grains, crystal malts, and rich caramel all lay down a sturdy base. Depth galore if a little sweet.

The flavor profile isn't as sweet as the smell led me to believe, which is a good thing. The citrus runs hand in hand with the aroma from beginning to end while the wildflower honey, and resinous really stand tall on the finish. Caramel and toasty grains lay a solid base but never interfere with the depth of the hop profile. Pretty damn good!

The body is lighter than expected, weighing in at medium with a surprisingly light feel across the tongue. Bitterness grows and lingers but never extends past moderate. The swallow brings a drying touch of peppery alcohol that adds to, instead of detracts, from the overall quality of the beer.

I've enjoyed this beer since the first year it came out and always pick up at least one 4-pack a year. It's a touch sweeter than my favorite of the style but the hop profile is deep and the overall flavor drips with citric goodness. A sturdy, delicious malt backbone holds everything together.

Poured in a New Glarus pint glass

A) cloudy, hazy, orange, amberish, color with a white two finger head that leaves a good amount of lace. Can't see through the beer and not a lot of light passes either. Low amount of nuculation

S) Very aromic, dank, pine, grapefruit, mango, orange, caramel, malt, sweet

T) Sweet candy, pine, citra, caramel malt, bread, lots of flavor and very sweet, Juicy

M) Low carbonation, coats the mouth with sweet nectar a tad syrupy too

O) A pretty damn good DIPA, pure Wisconsin in a bottle. Almost drank the entire four pack in one night. Cheers!

Big IBU yet still not a palate eraser. Fear and trepidation as I pour the bottle, examining for the pine cone. Liquid hop pellet level of IBU, very craftily malted down and therefore drinkable. Cloudy appearance. Fresh bottle from 20 West Wine and Spirits.

12oz bottle, pours a hazy, rusty-tangerine color with a frothy, off-white head that holds good retention, and leaves nice, thick lacing on the glass. Aromas are fresh pine & citric hops, earthy, sweet bread; caramel malt noticeable on the nose as well. Huge bready malt backbone with loads of caramel, followed by fresh, dank, piny hops with pungent grapefruit pith. Super creamy, maybe a little too full, but the creaminess is nice. Finishes bitter with lingering pine. Overall, it's a nice unique DIPA. Not sure that I'd get it again, but I did enjoy it.

Pours a HUGE, dense, frothy off-white head oozing in hop resin that has insane persistence and clings desperately to my glass. A WHOLE HOP CONE IS IN MY GLASS! Nice, resiny hop aroma blends with the sweet malt to make for a candied citrus rind aroma (but not that sweet). Straw and a slight burnt sienna color. Starts off bitter and bright with HUGE notes of hop resin. As the bitterness builds, it becomes dry and notes of grapefruit and citrus rind. The bitterness lingers and lingers. This almost tastes sticky it is so resiny.

Overall, I like this. It's very hop-resiny, which I don't typically like, but this works pretty well.
If you like your hops RESINY and sappy, then this is for you!

EDIT: I wanted to updated this review because this really has become my go-to hoppy drink. Fresh, it's wonderfully aromatic and slightly overly bitter, but if I let it sit for a few weeks or months, it subdues things to an absolutely wonderful, beautiful place.
Overall, I just really, really like this one.

Appearance: Pours a hazy caramel brown with a touch of golden orange…a thin layer of off white head did form and remains…could be more…(3.5/5)

Smell: Tons of bitterness…strong dank, woodsy, piney hops aroma…this thing is very much a hops driven wagon…caramel malt balance out things a bit with some nice sweetness and borderline creaminess…a very strong, almost intoxicating hops explosion…(4.25/5)

Taste: Whoa, this is heavy handed with hops! Tons of fresh woodsy/dank/earthy hops up front…it’s not overly bitter, just strong (and powerful) with hops flavor…bitterness does come in after I swallow, but again, not as strong as I would expect with all this hops flavor…there is a noticeable sweet caramel presence that rounds out the overall flavor and sweetens this runaway hops freight train…robust, rich, mildly creamy and flavorful…Yum! (4.25/5)

Moutfeel: Medium to full body with tons of carbonation…fluffs up bringing woodsy/dank hops flavor and slight bitterness to the palate…it’s got a bite to it that touches the outside of my tongue and a heavy hops feel on the back of my tongue…chewy, mildly creamy and somewhat smooth for such a strong brew…(4.25/5)

Overall: This is a wonderful brew…I’ve been delving deep into the imperial india pale ales lately and this one is stands out in strength and flavor categories…it doesn’t rely on any of the citrus or floral fluff to stand on, it’s straight up robust earthy/dank hops hitting the palate…a true palate wrecker…one thing I loved about this beer is that there was a hop cone in the bottle! I’ve never seen that done before…it was floating at the top of the bottle when I bought it, a sign of freshness I presume…I have to admit, I was excited to try this brew and it hasn’t disappointed…if I see this again, I will definitely buy it again…(4.5/5)

Yep, there's a whole hop cone...not sure how this makes me feel.

Murky red with 1 1/2 finger foamy off-white head.

Off scented aroma, a lot of sugary aroma present.

Bready, creamy, thick, sweet and sugary, drinkable, slightly dank, dry, lower carbonation, missing bitterness and bite..

Not sure how I feel about this brew... It's mixed on too many levels for me to quite make up my mind.

Deep golden yellow with a slightly hazy body. Outstanding frothy and dense white head, leaving considerable patchy lacing.

Pine tree and floral hop aromas with bready malt.

Resinous pine tree, tea leaf, and floral hops with a nice balance from bready and caramel malt. It's bitter, but still has great balance to it.

Mouthfeel is soft and medium body. Slight alcohol burn and a little bit astringent.

I was expecting this to be a decent IPA, but found it to be pretty damn good. I'd definitely buy it again.

Lupulin Maximus Imperial IPA pours a dark copper color with a nice small lacing head, and the best part a whole hop cone floating in the top. Very hoppy floral aroma. The taste is very bold and strong hoppy flavors. Good full flavor, could use just a hint more carbonation. Overall a fantastic IPA, love the hop in each bottle.

12oz bottle poured into an Imperial pint glass.

A - Tall and tight off-white head holds beautifully. The pour goes right through a whole cone hop in the neck of the bottle resulting in a hazy amber beer. Tons of sticky lacing all the way down.

S - Splendid wet feel to these hops. I get nice citrus and pine but an underlying flower like bouquet. Toasty malts also sit in the background.

T - Malt plays an important role in this beer. It comes across as very toasty with a dry feel to it. The malt carries through nearly the entirety of the flavor. Hops show up early and are citrusy here as well. The flavor finished up with a melon/pine hop note and some spicy alcohol. The bitterness is present throughout the whole flavor and although it finishes with a strong bitterness it never becomes overly sharp.

M - Semi-dry, medium to medium-full bodied, medium carbonation.

O - Excellent looking beer and also a cool perk having a hop cone in the bottle. Great freshness to the beer. Balanced yet hop forward and spread out bitterness instead of all at the backend.
