The wine list at Mastro's Costa Mesa arrives like the restaurant itself — heavy, intentional, and not shy about what it is. This is a Napa Cabernet temple dressed in old-Hollywood lighting, and the list makes no apologies for it. If you showed up hoping for adventurous pours, you read the room wrong.
Four hundred to six hundred labels sounds impressive until you realize a significant chunk is Napa Cabernet in various expressions and price brackets — Caymus Special Selection, Stag's Leap CASK 23, Opus One, Screaming Eagle if you're lucky. Bordeaux and Burgundy get respectable representation, and Washington State sneaks in a few bottles worth noticing. The white wine program — anchored by Aubert and Peter Michael Chardonnay — is genuinely strong for a steakhouse, though it's clearly the supporting act. Don't come looking for natural wines, Italian deep cuts, or anything from the Southern Hemisphere.
Twenty to thirty-five by-the-glass options is a generous count, and the price floor starts around $18 and climbs fast — you're regularly looking at $30–$50 for anything worth ordering. Silver Oak Alexander Valley shows up as a recognizable pour that at least delivers on the promise. Rotation appears minimal; this list is built to be stable, not surprising.
Silver Oak Alexander Valley Cabernet Sauvignon — $80–$120/bottle (est.)
In a list full of three-digit trophy wines, Silver Oak Alexander Valley is the one that actually drinks proportionally to what you're paying. It's approachable, reliable, and won't require a post-dinner financial audit.
Peter Michael Chardonnay
Everyone at the table is ordering Cabernet and ignoring this. Peter Michael makes some of the most serious Chardonnay in California, and here it sits on a steakhouse list getting skipped by every table ordering the bone-in. Order it with the seafood tower and feel very smart.
Screaming Eagle
If it's available by the bottle, the markup will be theatrical. Screaming Eagle belongs in a cellar or a charity auction, not a steakhouse environment where you're splitting attention between a Wagyu and a live piano set. The juice is real; the value proposition at restaurant markup is not.
Stag's Leap Wine Cellars CASK 23 + Bone-in Filet Mignon
CASK 23 has the structure to stand up to a serious cut of beef without steamrolling the tenderness that makes a filet worth ordering. It's the right amount of Napa gravitas without going full cult-wine circus.
✔️ The Bottom Line
Mastro's Costa Mesa does exactly what it promises — a polished, deep, Napa-forward list in a room built for expense accounts and anniversaries. If you want value or discovery, you're at the wrong restaurant; if you want the definitive Orange County steakhouse wine experience done with genuine care, this delivers.
