Wine by the Glass Programs

Before the mid-1970s, the concept of wine by the glass as we know it today was virtually non-existent. Restaurants typically offered only a generic house red or white, a basic option served without specific varietal or vintage details. That changed when distributors and beverage professionals began experimenting with displaying individual bottles at the bar, giving guests the ability to select a specific varietal without purchasing a full bottle. This shift fundamentally changed wine culture in dining establishments, allowing consumers to explore regions, grapes, and producers in a way that had simply never been possible. By the late 1980s and early 1990s, even prestige bottlings were finding their way into by-the-glass programs; Opus One, for instance, used glass sales through the Robert Mondavi salesforce as a strategy to manage its bottle price in the on-premise market. The next major leap came with technological innovation. Greg Lambrecht launched Coravin commercially in the US in 2013, enabling restaurants to pour premium wines by the glass from bottles that remained effectively sealed, and the by-the-glass era entered an entirely new chapter.

• Before the mid-1970s, restaurants offered only a generic red or white house wine with no varietal or vintage specifics.
• The concept expanded rapidly once distributors began promoting varietal selections displayed openly at the bar in the late 1970s and 1980s.
• Opus One pioneered high-end BTG programs in the late 1980s and early 1990s through a national salesforce initiative using custom mini-decanters.
• Coravin, launched commercially in the US in 2013, enabled premium wines to be poured by the glass without ever removing the cork.

The guiding principle for building a BTG list is that less is more. Industry professionals consistently recommend a core program of 2 to 12 wines; anything beyond 12 selections becomes very difficult to execute profitably, because every opened bottle must be sold quickly before quality deteriorates. A minimum program will feature at least one house red and one house white, while a mid-sized program typically offers 2 reds and 2 whites at varying price points. The largest practical programs feature 6 reds and 6 whites. At their heart, the wines chosen for a BTG list should be the venue's best sellers, since slow-moving selections risk waste from opened, unsold bottles. Savvy wine directors balance familiar, high-velocity varietals with a small number of discovery wines to satisfy both the comfortable and the adventurous guest. Seasonality matters too: more refreshing whites and rosés in warmer months, and richer, fuller-bodied reds in cooler seasons, can meaningfully lift sales velocity. Most restaurants rotate their BTG selections seasonally, roughly every 3 to 6 months, though active wine bars may refresh even more frequently to keep the list relevant and to minimize waste.

• A core BTG program should contain 2 to 12 wines; 12 is generally considered the upper limit for profitable operation without advanced dispensing technology.
• A minimum program features 1 house red and 1 house white; mid-size programs commonly offer 2 reds and 2 whites at different price points.
• Only fast-selling wines should appear on the BTG list, since opened bottles must be sold quickly to avoid quality loss and financial waste.
• Most restaurants rotate BTG selections every 3 to 6 months, while wine bars may rotate as frequently as every 3 months.

Pricing a BTG program correctly is one of the most consequential decisions a beverage manager makes. The most widely used benchmark is to price a single glass at approximately the wholesale cost of the entire bottle. This means that if a bottle was purchased at a wholesale cost of $10, the suggested glass price is $10, effectively generating a full return on the bottle from the very first pour. The remaining pours then represent nearly pure profit margin. The industry standard average BTG price range runs from $8 to $15 per glass, though premium markets like New York and San Francisco may see some establishments charging $20 to $30 per glass for exceptional bottles. Pour cost, defined as inventory usage divided by total glass sales, is the key metric for measuring program health; a target pour cost for BTG wine typically falls between 20 and 25 percent. The 80/20 rule is a reliable pattern in BTG sales data: roughly 80 percent of revenue is generated by just 20 percent of the selections. This reality underscores the importance of regular sales analysis and the willingness to replace slow sellers with proven performers. Many programs also use bracketing, a psychological pricing strategy that places lower-cost and higher-cost options alongside a mid-range target wine, subtly nudging guests toward the intended sweet spot.

• The most common BTG pricing rule is to charge the wholesale cost of the bottle for a single glass, recovering the full bottle cost on the first pour.
• Industry standard BTG prices range from $8 to $15 per glass, with premium venues in major cities reaching $20 to $30 for top selections.
• Target pour cost for BTG wine is typically 20 to 25 percent; the profit margin on glass pours can reach 75 to 80 percent.
• The 80/20 rule applies consistently to BTG programs: 80% of glass sales revenue comes from just 20% of the selections.

Oxidation is the central enemy of any BTG program. Once a bottle is opened, oxygen contact begins immediately, causing wine to lose freshness, vibrancy, and commercial value. Without preservation systems, opened bottles are typically only serviceable for one to two days, and on larger lists with 25 or more BTG selections, some wines may sit open for several days. Several technologies have transformed this challenge. Vacuum pump systems slow oxidation by removing air from the bottle, extending shelf life by a day or two. Inert gas blanket systems, using argon or nitrogen, replace the headspace above the wine with a protective layer that prevents oxygen contact, extending shelf life significantly. Coravin's Timeless system works differently and more powerfully: a precision-engineered needle pierces the natural cork, argon gas pressurizes the bottle to drive wine out, and when the needle is removed, the cork reseals itself. Oxygen never enters the bottle, allowing wine to continue aging undisturbed, potentially for years. Enomatic automated dispensers use argon gas preservation to maintain opened bottles for 30 days or more while also offering precise, programmable pour control and temperature management. For sparkling wines, dedicated systems inject CO2 to maintain pressure and carbonation for up to four weeks.

• Without preservation, opened BTG bottles should be consumed within 1 to 2 days; sparkling wines deteriorate even faster without intervention.
• Coravin Timeless systems use a needle and argon gas to pour without removing the cork, leaving remaining wine protected for months or even years.
• Enomatic dispensers use argon gas preservation to maintain wine quality for 30 days or more, with programmable pour sizes and controlled serving temperature.
• Sparkling wine preservation systems inject food-grade CO2 to maintain pressure and carbonation, extending freshness for up to four weeks.

Even the most carefully curated and priced BTG program will underperform without well-trained staff. Pour consistency is the foundation of profitability: even a half-ounce over-pour per glass can represent thousands of dollars in lost revenue over time. The industry standard pour for still wine is 5 ounces, yielding exactly five glasses from a standard 750 ml bottle, while sparkling wine is typically served in a 4-ounce pour. Dessert wines and fortified wines carry smaller standard pours of 2 to 3 ounces due to their higher alcohol and sweetness levels. Pre-shift tastings, where staff sample new BTG additions and discuss flavor profiles and food pairing suggestions, are widely considered best practice for building team knowledge and confidence. Training staff to recognize bottle faults, especially cork taint (TCA), is essential; a corked bottle poured to a guest represents an immediate waste of a full glass and a service failure. Restaurants increasingly prefer to offer a small taste to a guest at the table before committing to a full pour, reducing the risk of a wasted glass from an unsatisfactory selection. Regular team meetings to review sales data, discuss slow sellers, and prepare for upcoming list changes keep a program dynamic, responsive, and profitable.

• The standard BTG pour for still wine is 5 ounces (150 ml), yielding five glasses from a standard 750 ml bottle.
• Sparkling wine is typically poured at 4 ounces; dessert wines at 2 ounces; fortified wines at 3 ounces.
• Pre-shift tastings of new BTG wines are widely considered best practice, building staff confidence and enabling better guest recommendations.
• A half-ounce over-pour per glass, multiplied across a full service, can cost thousands of dollars in lost revenue annually.

Effective inventory management is the operational backbone of a successful BTG program. The fundamental tension in any BTG program is between breadth of selection, which delights guests, and the risk of spoilage from slow-selling, open bottles. Analyzing past sales data to forecast demand allows a wine director to order the right quantities and avoid both overstocking and running out of popular options. Modern point-of-sale systems and wine management software can flag slow-moving BTG bottles in real time, enabling rapid decisions about whether to discount, feature as a staff recommendation, or simply remove from the list. Industry data suggests that the average on-premise beverage operation loses approximately 20 percent of potential revenue to spoilage, over-pouring, and inventory shrinkage. Automated dispensing systems with precise portion control can almost entirely eliminate over-pouring losses. A practical waste-reduction strategy is to ensure that every BTG selection is also a high-velocity seller; a wine that moves fewer than a bottle or two per week on a standard program is a candidate for removal unless preserved by an advanced system such as Enomatic or Coravin. Tying BTG selections closely to the food menu, recommending them as specific pairings for featured dishes, is one of the most effective tools for accelerating bottle turnover.

• The average hospitality operation loses approximately 20 percent of potential beverage revenue to spoilage, over-pouring, and shrinkage.
• Regular sales analysis, ideally using POS data, is essential for identifying and replacing slow-moving BTG wines before they become financial liabilities.
• Automated wine dispensers with programmable pour control virtually eliminate over-pouring as a source of revenue loss.
• Pairing BTG selections directly to specific menu dishes is one of the most effective strategies for accelerating bottle turnover and reducing waste.
