Kastellet runs across three floors of a building on Hegdehaugsveien, the shopping street that climbs from the centre toward Bislett in Oslo. It opened as a wine house from the team behind We Come in Peace, with head chef Hanne Rutgerson, and splits its floors between a wine bar, a cocktail bar and a members' wine cellar.
The address suits drinkers who want a serious wine list with food alongside, and who are happy to move between floors as the night runs. It works less well for anyone after a cheap quick pint, because the focus is wine and the pricing sits at the upper end for the neighbourhood.
The ground floor holds the wine bar and a restaurant of around 70 seats, which is where most first visits start. Dagens Naeringsliv covered the opening and laid out the layout, with a bar menu and a kitchen running alongside the by-the-glass pours. The Aftenposten restaurant guide lists the house at Hegdehaugsveien 25 and treats it as a wine destination rather than a passing bar.
One floor up sits the cocktail bar, decorated in what the coverage describes as an eclectic mix of 1970s sofas and classic Danish design, set among plants. That room gives the building a second register, so a night can move from a glass of wine downstairs to a cocktail above without changing venue. The split keeps the wine bar focused while still offering spirits drinkers a seat.
The basement is the part that sets Kastellet apart. It opened with around 6,000 bottles as a private wine club, where members paying a monthly fee get tastings, storage for bottles they have bought but not finished, and advice on serving and buying. That cellar gives the house a depth most Oslo wine bars cannot match, and it anchors the building's identity around wine rather than food.
The by-the-glass and bottle lists carry the room, with the kitchen sending small plates built to drink alongside rather than a heavy meal. Prices read as a step up from a casual neighbourhood bar, in line with the cellar and the setting. The trade is range and seriousness for the higher spend, which is the deal a wine house on this street is built to offer.
Best time to go is an earlier weekday evening for the ground-floor wine bar, when the room is calmer and the list is easiest to work through with the staff. Reservations help for the restaurant, while the bar floors take walk-ins for a glass. The cocktail floor is the late seat once the kitchen winds down.
What sets the house apart from a standard wine bar is the seriousness of the cellar behind the by-the-glass list, which gives the staff real range to pour from rather than a short printed selection. The three-floor format lets a visit move from a focused glass of wine at the ground-floor bar to a cocktail upstairs as the evening runs, so one address can carry a whole night. The team behind it has built a reputation in Oslo for rooms with a point of view, and Kastellet reads as their most ambitious to date. For drinkers who treat wine as the main event rather than an afterthought, the depth here is the reason to climb the street.
Kastellet adds a heavyweight to the Hegdehaugen end of the city, and it belongs in our roundup of the best wine bars in Oslo and the global best wine bars worldwide guide. Plan a wider night from the Oslo bar guide.
