But this post is about something more specific: how to actually build those products from the ground up.

If you’ve been following along, you know we talk a lot about trends. Today, we’re getting into execution, specifically, how to successfully develop formula wines, meaning wines that require TTB approval on the recipe before production and packaging can begin. Below is the DGW process that has helped countless Clients and Members craft distinctive, market-ready products in the formula wine category:

Defining Your Desired Flavor and Product

At the start of any R&D process, the very first step isn’t sourcing flavors or running bench trials, it’s getting clear on what you actually want to make.

That may sound obvious, but this is an essential first step. Winemakers frequently run into trouble because they don’t know how to articulate what they’re looking for in a flavor to a supplier. Many start mixing concoctions based on “kitchen instincts” rather than scalable production logic, or they end up with bench trial after bench trial that’s “just not right.” If you want to understand why formula winemaking demands a distinct skillset from traditional winemaking, our Back to Enology Part 2: Formula Wines Are Sophisticated Wines is worth a read.

The right terminology will take you further than you think when communicating with flavor companies, ingredient suppliers, or consultants.

Describe the product you’re envisioning. Are you looking for a flavor combination that matches the wine-base (think Grapefruit Sauvignon Blanc, Peachy Moscato, or Black Currant Cabernet)? Or are you aiming for something more cocktail-inspired, like a Cherry Wine Martini, a Jalapeño-Peach Wine Spritzer, or a “Butter Beer” Wine Cocktail? The creative possibilities here are genuinely wide open.

Then get specific about the flavors themselves. For any single flavor concept, there can be hundreds — sometimes thousands — of options that are used as that descriptor. Take black currant, one of the standout flavors of 2026. On its own, black currant can read as brambly, green, woody, floral, and fruity all at once. If your goal is to highlight the concentrated, fresh fruit character of the berry, you need to say exactly that to your flavor supplier: “I’m looking for a fresh black currant flavor that really emphasizes the concentrated, fruity essence of the fruit.” Precision at this stage saves significant time and money down the line. If your product involves multiple flavors, describe each one with the same level of detail. This is where working with a consultant trained in flavor and sensory science can make a real difference. And, if you want more examples on flavor differentiation, listen to our upcoming podcast episode on using flavor trends in the winery.

Finally, know your packaging before you finalize your formula. Different packaging formats carry different chemical and microbial requirements for the wine going into them. Canned wines, for example, have meaningfully different QA/QC needs than bottled wines. We’ve outlined these differences in detail in the DGW Canning QA/QC Spreadsheet versus the Bottling QA/QC Spreadsheet.

Master the Prototype (Bench Trialing) Phase

The prototype phase – or bench trialing, as we call it in the wine world – is where even experienced winemakers can begin to lose their footing. The complexity of flavor interactions is real, and it’s easy to get overwhelmed. Unlike standard winemaking additives that come with straightforward recommended dosage rates, flavor ingredients don’t always behave predictably. They interact, shift, and evolve in ways that require a more deliberate, methodical approach.

While I’ll be diving into a more comprehensive set of prototyping strategies in an upcoming podcast episode, here are my top three tips for producing stronger formula wine prototypes right now.

1. Build your base wine first. Before you introduce any flavors into the equation, establish your base wine. This means blending together all the wines you intend to use in the final product — whether that’s one variety or a combination of ten or more. The number isn’t what matters. What does matter is reproducibility: your base wine needs to be something you can reliably recreate a year or two down the line. Once that foundation is locked in, let it serve as the consistent starting point for every prototype you develop. Skipping this step introduces too many variables and makes it nearly impossible to evaluate flavors accurately.
2. Limit your flavor options. Sensory fatigue is a real challenge in bench trialing, even for seasoned winemakers. When flavors enter the picture, they introduce a new sensory dimension that can quickly become difficult to evaluate objectively. For that reason, I recommend testing no more than five flavors or flavor combinations at a time. Ideally, keep it to three or fewer. One important note: what you smell in the bottle is not necessarily representative of how a flavor will present in the wine. Always evaluate in context, not in isolation.
3. Understand that more flavor is not always better. This is perhaps the most counterintuitive principle in formula winemaking, but it’s one of the most important: restraint often yields better results than abundance. In my experience, I more frequently advise winemakers to reduce their flavor dosage rather than increase it. Here’s why:
   1. Flavor character: Certain flavor types can make a wine feel heavy, harsh, or even chemical-like when used in excess. If the wine starts to take on those qualities, it’s a clear signal to reduce the flavor concentration.
   2. Synergism: Flavors interact with one another in complex ways. The combined effect of multiple flavors, plus the flavors provided by the base wine, is not simply the sum of their parts. It can be something entirely different, and not always in a desirable direction. This concept is elusive, but mastering it is essential to producing high-quality formula wine.
   3. Background flavors: Not every flavor is meant to be identifiable. Some, particularly many citrus flavors, function as supporting elements, adding “lift” or brightness to the overall profile without announcing themselves. Resist the urge to chase recognizability for every ingredient in your formula.

Bench trialing is as much an art as it is a science. A structured, patient approach will save you time, reduce waste, and ultimately lead to more consistent, higher-quality products.

Compliance, Batching, and Shelf-Life Considerations

Once you’ve landed on a formula you’re confident in, the next step is getting it documented and submitted to the Alcohol and Tobacco Tax and Trade Bureau (TTB) for approval. This isn’t a formality to rush through. TTB review confirms that every ingredient in your formula falls within current regulatory compliance allowances for wine. Batching should not begin until that approval is in hand.

With approval secured, you’re ready to produce your first batch. This is also the stage where packaging decisions become especially important. If you’re filling into cans rather than bottles, be aware that the two packaging formats are not interchangeable from a winemaking and processing standpoint.

Cans present a fundamentally different environment for flavored wine products. The interaction between metal packaging and added flavor ingredients can diminish flavor intensity or alter the overall sensory profile in ways that may not be apparent until after packaging. Beyond flavor, cans are an anaerobic environment, meaning oxygen is essentially absent. This change in packaging environment introduces distinct microbiological risks that require consideration during processing and before packaging. Depending on the ingredients in your formula, additional preservative measures may be necessary to ensure product quality and stability in that format.

Finally, the wine’s shelf-life should be considered. Formula wine products behave differently than conventional table wine, and they don’t all age the same way. Many have a more limited shelf-life, which is why it’s important to set aside a portion of every packaged batch specifically for ongoing evaluation.

Routine sensory and stability monitoring over time is one of the most effective ways to establish realistic shelf-life expectations for a product. It also helps to identify what adjustments might be needed in future batches. When something does need to be corrected, working with someone who has experience troubleshooting formula wines will almost always get you to the right answer faster than working through it alone.

Ready to do this right?

Let’s be honest: the formula wine category is full of products that have missed the mark. I know, because I’ve tasted more than my fair share of them. But that’s exactly the opportunity. In a crowded and growing segment, quality and creativity stands out.

The wineries that invest in getting their process right, from a well-crafted prototype to a compliant, shelf-stable finished product, are the ones that will define this category. The ones that don’t? They become a cautionary tale at someone else’s bench trial.

That’s where DG Winemaking comes in.
