Wingman Metrics
The wine list at Isa Bistro doesn't announce itself with a thud — it's a focused, tightly curated document that feels like it was built by someone who actually drinks wine. There's a sommelier in the house and it shows: you won't find the usual Napa Cab and Pinot Grigio filler taking up real estate here. What you get instead is a list that nudges you toward regions you might not have ordered on your own.
The Old World leans hard into Italy and Austria, with strong representation from Puglia via Cantele and some genuinely interesting Austrian bottlings from Schloss Gobelsburg. The Cistercian bottling from Gobelsburg — a Grüner Veltliner-forward blend rooted in ancient monastic viticulture — is the kind of thing that earns a list credibility fast. Raul Perez appearing anywhere in Maine is a small miracle; his Galician wines (Bierzo, Rías Baixas) are cult-level for a reason, and seeing his name here bumps the list from 'nice' to 'serious.' The Txakolina and Arneis selections round out a white wine program that prizes texture and brightness over crowd-pleasing weight.
With 12-20 pours available, the by-the-glass program punches above its weight for a cozy neighborhood bistro. Expect the 2023 Rosé and the Cantele Teresa Manara Negroamaro to anchor the list — a smart pairing of a session-friendly pink and a structured southern Italian red. Rotation appears to track the seasons, which means the list you see in February probably won't be identical to the one in August.
Cantele Teresa Manara Negroamaro — $48
Cantele's Teresa Manara is a benchmark Negroamaro from Puglia — dark fruit, dried herbs, genuine structure — and it's the kind of wine that retails around $18-22. At a neighborhood bistro in Maine, finding it on the list at a reasonable markup is a win. Order it with the tagliatelle Bolognese and don't look back.
Schloss Gobelsburg Cistercian
Most tables at Isa are going to walk right past this one, and that's their loss. Gobelsburg is one of Austria's great estates, and the Cistercian blend is an entry point into their world that over-delivers on complexity for the price. It's not flashy, it doesn't have a recognizable label, and that's exactly why it's still available when you arrive.
2023 Rosé
No producer is listed with this one, and anonymous rosé at a $$$ bistro is a yellow flag. It's almost certainly a serviceable pour, but when there are wines on this list from Raul Perez and Gobelsburg, spending your money on an unattributed pink feels like ordering house bread when the charcuterie is right there.
Txakolina + Lobster Tostada
Txakolina — that sharp, slightly effervescent Basque white — was practically engineered for seafood. Its high acid and subtle salinity cut right through the richness of lobster while amplifying any citrus or heat in the dish. It's an unexpected call at a Maine bistro, but it's the right one.
The Bottom Line
Isa Bistro is a Wild Card in the best possible way — a warm, owner-run neighborhood room with a wine list that has no business being this interesting. If you're in the Old Port and you care about what's in your glass, this is where you go.
East End · Portland · Sushi / Japanese
Mr. Tuna isn't a wine destination — it's a great sushi spot that happens to have two sensible, well-chosen bottles and a local can that makes the experience feel intentional. Come for the hand rolls, drink the Vinho Verde, and don't overthink it.

A fast-casual raw bar with a wine list that punches well above its category — the French-only focus is a feature, not a limitation. If you're eating oysters in Portland, this is where you want to be drinking.

Old Port · Portland · Seafood, American
Scales is playing a different game than the tourist-trap seafood spots on either side of it — the wine list is genuinely Old World-focused and well-matched to the food, which is rare and worth noting. If you're eating clams and mussels on the Portland waterfront, this is where you want to be doing it with a glass in hand.

Regards isn't trying to be a wine bar, but whoever built this list understands exactly what the food needs and went hunting for it. If you're in Portland and want a bottle that actually earns its place on the table, this is the move.

Chaval is punching above its weight class for a neighborhood brasserie in Portland — the list is small but curated by someone who actually cares, with pricing that doesn't punish curiosity. If you're open to going off the beaten path (xarel-lo, South African grenache blanc), this is a genuinely rewarding room to drink in.

Healdsburg Avenue / Downtown · Healdsburg · Bistro
Bistro Lagniappe is a Wild Card in the best sense — a small-town bistro hiding a wine list with genuine ambition and some serious French muscle. The markups keep it from being a Rager, but if you're in Healdsburg and want to drink something real, this list deserves your attention.

Tacoma · Tacoma · Bistro
Bar Bistro is genuinely surprising — a Tacoma neighborhood spot quietly housing some of Washington and California's most coveted reds. The list isn't balanced, the pricing reflects the prestige labels, and the vibe doesn't quite match what's in the cellar, but if you know what you're looking for, there's something real here.
