O-Bomb is not a quiet little fruit beer. Ghost Train Brewing Company built this one as a high-octane Imperial Orange-Tangerine Fruited Sour, and the numbers set expectations before the first sip: 13.9% ABV. That is closer to a carefully paced cocktail than a casual patio sour. The profile leans into orange and tangerine, while the strength gives it a heavier, warming frame than the bright citrus aroma might suggest. My rating is 3.76 out of 5.

My first impression of O-Bomb
The can makes the intent obvious: vivid, playful and designed to get noticed. In the glass, I get a saturated golden-orange appearance, more like orange nectar than a pale, crisp wheat beer. The nose reads as sweet citrus first, led by tangerine, with a sour-beer tang underneath. That is a natural fit for a beer that names orange and tangerine in its style description. It does not present itself as a restrained farmhouse sour or an austere Belgian ale. It is a big, fruit-led pour that wants to be vivid.
The key is to let the alcohol register as part of the shape, not the whole story. At 13.9%, O-Bomb carries the kind of warmth that can round out sweetness and make the finish feel fuller. I would not expect the snappy, light-body finish of a sessionable kettle sour. This is more concentrated, with fruit-sour character moving across a stronger, more substantial base. The style is a cousin to other fruited sours, but the imperial strength shifts it firmly into sipping territory.
If sour beer is new to you, my advice is to take a look at what makes a gose different first. Gose is generally a lighter, tart style and can be a gentler introduction than a high-gravity fruit sour. For a little more background on the sour family, I also like our guide to Berliner weisse, a very different and usually much lower-strength expression.

Ghost Train Brewing Company: Birmingham roots
Ghost Train was part of the wave of independent breweries that gave Birmingham, Alabama, a wider range of local beer. The brewery was founded in 2014 by Patrick Small and Taylor DeBoer. Its name and visual identity had a strong connection to the city, and its range moved through familiar craft styles as well as more adventurous releases. O-Bomb is an example of that willingness to push beyond an everyday pale ale: a high-strength sour with a bright citrus idea and a name that feels built for a bold label.
The brewery’s story also has a difficult last chapter. Ghost Train ceased operations after filing for Chapter 7 bankruptcy in 2024, and its former brewery is closed. That background matters when looking for O-Bomb now. It is not a beer from an operating brewery with a current tap list or a dependable, ongoing production schedule. Any cans still circulating are likely to be limited, and freshness is especially important for a fruit-forward sour. I would check the can date if one turns up, and I would not assume a listing means stock is still available.
Ghost Train had other beers that made a mark locally, including its hazy Double IPA, Ghost in the Machine. That is a useful comparison because it shows the brewery could take a bigger, more intense format in a completely different direction. Where that IPA is built around hops and a familiar bitter-sweet balance, O-Bomb puts fruit and sourness up front. The brewery also made XXX OJ, another citrus-minded beer that gives fans a separate way to explore Ghost Train’s playful side.
ABV, IBU and ingredients
The most important published specification is the 13.9% ABV. That is unusually strong for a fruit sour and explains why I treat it as a small-pour beer. There is no verified, brewery-published IBU figure I could confirm. Some beer databases list IBU as N/A, so I am not going to turn that into a made-up bitterness number. I also could not verify an official hop bill, malt bill or calorie figure. Without a brewery specification sheet, assigning exact ingredients or calories would be guesswork.
That missing recipe detail is worth keeping in mind when interpreting the flavors. Orange and tangerine are the recognizable fruit cues, but that does not establish whether the brewery used juice, puree, zest, flavoring or some combination. Likewise, a sour beer can be acidified in different ways, and the product description alone does not establish a particular fermentation method. So I describe what the beer is presented as and how its profile reads, not an unverified recipe.
A common question is whether IBU tells you how sour a beer will taste. It does not: IBU is a measure associated with hop bitterness, not a direct sourness scale. Our explainer on what IBU means helps separate bitterness from acidity. In O-Bomb’s case, the lack of a listed IBU is not an obstacle to understanding the main appeal. Its identity rests on fruit, sour character and high alcohol, rather than a published hop target.

Tasting notes: citrus, tartness and warmth
Appearance
O-Bomb appears golden orange with enough body in the color to look substantial in a glass. It is more vivid than a classic pale sour and fits the orange-tangerine cue. I would serve it in a tulip or small stemmed glass rather than a pint glass. That shape concentrates the aroma, while a smaller portion makes the beer easier to enjoy at its own pace. A serving around 5 to 6 ounces is a sensible starting point at this strength.
Aroma
The aroma is the most immediately inviting part of the concept: citrus-forward, with orange peel and sweet tangerine character coming to mind. There is an acidic edge underneath, the reminder that this is a sour rather than a citrus soda. I would expect the impression to be lively rather than perfumey, with the fruit carrying the first sniff and the stronger base showing more as the beer warms. The actual intensity can vary from can to can and with storage, which is another reason to look for a fresh one.
Flavor and finish
On the palate, the orange-tangerine theme should make the first impression. A bright fruit note meets a puckering sour edge, while the 13.9% ABV fills out the middle and leaves a warming finish. This is where O-Bomb’s cocktail inspiration makes sense: it aims for the expressive, sweet-tart balance of a mixed drink, not the quick, thirst-quenching snap of a low-strength sour. I would expect the acidity to keep the sweetness from feeling one-note, but the higher alcohol means the overall impression is still rich.
I would keep the serving cold but not ice-cold. A little time in the glass allows the orange to open up, while very low temperature can mute the more delicate fruit aromas. The beer should not need garnish to explain itself, though a slim piece of orange peel alongside it could echo the profile without changing the beer. I would avoid adding juice or syrup: the drink already has a strong fruit premise, and extra sweetness can make a 13.9% beer feel heavier than it needs to.
Sours cover a wide spectrum, from softly tart to sharply acidic, and the style name does not promise a single intensity. If you want to compare the range, our guides to lambic and wild ales and the best sour beers give two useful points of reference. O-Bomb sits closer to the fruit-forward, modern end than the earthy, aged, traditionally blended end of the sour spectrum.
Food pairings for O-Bomb
The sweet-tart citrus profile gives me a few good food routes, but I would keep portions and seasoning balanced because the beer is strong. Salty, fatty foods can soften acidity and bring the fruit forward. A crisp fried chicken sandwich, salty fries or soft pretzels with mustard would work well in a casual setting. The acidity cuts through richness, while the orange note can complement a little char or spice.
For a more substantial pairing, try grilled pork with an orange glaze, roast chicken with citrus and herbs, or a plate of sharp cheddar and aged gouda. Keep the glaze restrained, since a syrupy sauce plus a fruit beer can turn the pairing too sweet. A small pour alongside spicy shrimp or tacos with a citrusy salsa could also be interesting, although I would skip the hottest chile levels. Too much heat and a big alcoholic beer can amplify each other rather than balance.
If the plan is a cookout, the tartness can complement smoked pork or grilled sausages, but this is not a beer I would use as a casual all-afternoon BBQ drink. Our beer and BBQ pairing guide has some lower-strength pairings for a longer meal. For dessert, citrus tart or a simple vanilla cheesecake makes more sense than a rich chocolate cake. A bright acidic beer can bring contrast to creamy desserts, but O-Bomb’s ABV still means a small serving is plenty.

How O-Bomb compares with other sour beers
O-Bomb is not trying to do the same job as Dogfish Head SeaQuench Ale. SeaQuench is a lighter, savory-leaning, salt-and-lime sour built for refreshment, and it is one of the easier modern examples to find. Compare the two through our SeaQuench Ale review: O-Bomb is the bigger, fruitier, stronger option, while SeaQuench is the one I would reach for in warm weather when the goal is a more relaxed drink.
Against a classic Flemish sour such as Duchesse de Bourgogne, O-Bomb is less about layered malt and wine-like acidity, and more about fruit clarity and punch. Likewise, Jolly Pumpkin La Roja leans on a more complex, rustic sour character. These are not direct substitutes, but they make the range easier to understand. O-Bomb is more of a contemporary, fruit-forward, high-strength statement than an old-world sour to nurse with a long meal.
Another comparison point is New Belgium La Folie, a wood-aged sour with a very different balance and texture. If O-Bomb’s bright citrus and high alcohol appeal, the adjacent fruity beer guide and our raspberry beer picks offer other fruit-led directions. Raspberry sours will be less citrus-driven, but the general fruit-and-acid combination is a shared thread.
Where to buy O-Bomb, and five similar beers to try
O-Bomb is not currently available from the brewery, which is closed, and I could not confirm an active national retailer listing for this exact beer. I would treat any remaining stock as limited and check the package date before buying. If O-Bomb is not available near you, here are five genuine sour or fruit-forward alternatives with existing Saucey links. The first three are tart fruit beers; the last two are more refreshing or citrus-driven sours. Delivery coverage depends on your location.
- Distinctive orange-tangerine fruit character
- A genuinely big, expressive sour with a cocktail-inspired idea
- Strong community rating of 3.76 out of 5
- At 13.9% ABV, it is not an easy-drinking session sour
- No verified public IBU, hop bill, malt bill or official calorie figure
- Ghost Train is closed, so finding fresh stock may be difficult
Final verdict
O-Bomb is memorable because it commits to its concept. The orange and tangerine direction gives it an immediately recognizable identity, and the imperial strength makes the beer feel closer to a bold dessert sour or cocktail-inspired pour than a simple thirst quencher. I like the fact that it sits at an unusual intersection: it is a fruit beer, a sour, and a high-alcohol release, all in one package.
That same strength is its main limitation. At 13.9%, O-Bomb asks for a small glass, a slow pace and a drinker who likes fruit-forward acidity with warmth behind it. It is less suited to a hot-day session than to a deliberate tasting pour after dinner. The brewery’s closure makes availability an added caveat; if you find it, freshness and storage history matter. At 3.76 out of 5, I would put O-Bomb in the worthwhile-but-specialist category: a lively idea with enough personality to be worth trying, provided you know what the ABV implies.
