I approached When Wine Tastes Best as a practical companion rather than a general wine encyclopedia. Developed by Floris Books, this free Food & Drink app is built around a biodynamic and lunar calendar for wine drinkers. Its purpose is quite specific: help you decide when a bottle may show at its best, then give you a repeatable way to plan tastings instead of relying entirely on guesswork.
That narrow focus is both its appeal and its main limitation. I would not install it expecting cellar management, bottle recommendations, food pairing lessons, or a replacement for a sommelier. I would install it if I already enjoyed wine and wanted to explore how tasting conditions, particularly lunar timing, might affect my experience. The app’s short description, “When Wine Tastes Best,” is a fair summary, but the useful question is how well it fits into an ordinary routine.
How I would use the calendar in real life
The most sensible starting point is simple. Before opening a bottle, I would check the calendar, note the suggested quality of the day, and decide whether the tasting is casual or important. That distinction matters. If I am opening an inexpensive bottle with dinner on a busy evening, I am unlikely to reorganize the meal around a calendar. If I am serving a bottle that has been saved for a birthday, a quiet weekend, or a small tasting with friends, the extra planning becomes much more worthwhile.
The app works best when treated as a planning reference rather than an authority that settles every question. Wine changes for many reasons: serving temperature, glass shape, decanting, storage, bottle variation, food, and personal expectation. A calendar can add another layer to the ritual, but it should not make you ignore what is actually in the glass. My preferred habit would be to check the day before shopping or opening, then record my own reaction afterward in a separate notebook or notes app.
That last step is important because the calendar gives you a framework, while your palate supplies the evidence. If I repeatedly enjoy a particular style on days the app marks favorably, I gain a personal pattern worth following. If my experience disagrees, I would trust the tasting first and use the calendar as a prompt for curiosity. This approach keeps the app enjoyable without turning a recommendation into a rigid rule.
A realistic dinner scenario
Imagine I have friends coming over on Saturday and plan to serve one red wine with a slow-cooked meal. Rather than opening the bottle immediately, I would check the calendar in advance and compare the available days. If the chosen date looks suitable, I might prepare the bottle normally, pay attention to its aroma and finish, and ask everyone to describe what they notice before discussing the lunar timing. That keeps the tasting reasonably honest and avoids influencing everyone’s first impression.
If the date is not ideal, I would not automatically cancel dinner. I might open the bottle anyway, especially if it is the only bottle available, and treat the result as a comparison. The app becomes more interesting when it encourages this kind of side-by-side thinking. Experienced users can open similar wines at different times, keep the serving conditions as consistent as possible, and write down impressions without pretending the experiment is scientifically controlled.
This is also where the app differs from usual wine alternatives. A conventional wine app may concentrate on ratings, regions, grape varieties, or shopping suggestions. Those tools are often better when I need to choose what to buy. This calendar is more useful after I have already chosen the bottle and want to decide when to open it. It does not replace a large tasting database; it offers a different question.
What the app is and what it is not
The core experience is intentionally specialized. It is not trying to teach all the fundamentals of wine, and that makes it less useful for someone who wants a beginner’s course. A newcomer may still understand the basic idea quickly, but the app will not necessarily explain why one bottle suits a particular meal or how to identify faults. For that, a structured wine guide or educational app would be a better first download.
For an experienced drinker, however, the narrow subject can be a strength. I do not have to scroll through endless tasting notes or commercial recommendations. I can consult the calendar, make a decision, and return to the bottle itself. That low-friction workflow is especially appealing to people who already own wine and want a small ritual around opening it.
The app is free to download, although it includes in-app purchases ranging from $1.49 to $7.99 per item. I would therefore explore the basic experience before paying for anything. The right question is not whether additional material sounds interesting, but whether it improves the way I personally use the calendar. Someone who checks it occasionally may find the free experience sufficient, while a committed follower of biodynamic wine timing may see value in expanding the reference material.
Settings, habits, and faster ways to use it
Settings worth checking before relying on it
My first practical check would be the device date and time. A calendar-driven app depends on showing the correct day, so an incorrect phone clock can undermine the entire routine. I would also look through the available preferences at the beginning rather than assuming the default display is ideal. The useful settings are likely to be the ones that make the calendar easier to consult repeatedly: anything related to date presentation, notifications, or how information is displayed deserves a quick look if available.
I would not turn on every reminder automatically. Wine drinking is not a task that needs constant prompting, and frequent alerts could make the app feel intrusive. A better pattern is to use a reminder only when I have a planned tasting, then disable it afterward if the app permits that choice. This keeps the calendar connected to a real bottle rather than turning it into background noise.
Another worthwhile check is whether the app presents the information in a way that suits quick decisions. If the calendar includes several levels or descriptive indicators, I would learn what each one means before using it to plan a special bottle. The goal is to recognize the visual language at a glance. Spending a few minutes learning the layout can save repeated searching later, particularly when I am cooking and do not want to study the screen for long.
A repeatable workflow for regular drinkers
I would use a three-stage routine. First, check the calendar when planning the week. Second, choose the bottle and serving conditions without changing too many variables. Third, make a short note after tasting. The note does not need to be elaborate. I would record the wine, the date, whether it was decanted, what food accompanied it, and my overall impression. This creates a useful personal reference that the calendar alone cannot provide.
The serving-condition note is a non-obvious but important improvement. If I open a bottle on a favorable day straight from a warm room, serve it in unsuitable glasses, and pair it with a strongly flavored dish, I cannot fairly judge the timing. Keeping those details visible helps separate a disappointing service from a disappointing calendar prediction. It also makes the app more useful for learning rather than simply confirming expectations.
For a small group, I would ask guests to taste before I mention the calendar result. This is a simple way to reduce suggestion. After everyone has formed an initial opinion, I would reveal the date and discuss whether the wine seemed expressive, muted, balanced, or simply different from expectation. The app then supports conversation without dictating the verdict.
Faster patterns for busy evenings
When I do not have time for a full tasting, I would use the app as a quick yes-or-no planning aid. If the calendar looks promising and the bottle is ready, I open it. If the date is less attractive but the meal is already planned, I continue anyway and avoid overthinking it. The important shortcut is deciding in advance how much weight the calendar will carry for that occasion.
I would also group bottles by importance. Special bottles deserve a calendar check, a controlled serving temperature, and a written impression. Everyday bottles need only a glance, if that. This prevents the app from making casual wine drinking feel like homework. It also means I spend attention where a difference would matter most: older, unusual, or emotionally significant bottles.
Another efficient habit is checking several possible dates before buying a bottle for an event. I would not use the calendar to choose the wine itself, but it could help me decide whether to host the tasting on one evening or another. That is a more realistic use than trying to consult the app at the last second while guests are already arriving.
For people who share wine with a partner or group, agreeing on a common routine can make the experience smoother. One person can check the date, another can handle serving, and everyone can write a quick independent impression. The app does not need to become a social game; its value comes from giving the group a consistent reference point.
Where the calendar needs a critical eye
The central trade-off is that lunar and biodynamic timing is not the same as a proven measurement of wine quality. I would approach the app with an open mind but also with restraint. A favorable day cannot rescue a flawed bottle, poor storage, or a badly matched meal. Likewise, a less favorable day does not prove that a good wine will taste poor.
Expectation can be especially powerful here. If I see that a day is supposed to be excellent, I may unconsciously search for evidence that confirms it. That is why tasting before discussing the calendar is one of my strongest recommendations. It does not eliminate bias, but it reduces the easiest source of it.
The calendar is also less helpful when I need immediate, conventional advice. If I am standing in a shop deciding between two unfamiliar bottles, I would rather use a reliable wine reference, ask a knowledgeable retailer, or read information about the region and grape. If I need food pairing guidance, a dedicated pairing resource will be more direct. This app answers a timing question, not every wine question.
Compatibility and practical expectations
The app supports devices running Android 5.0 or later, which makes it accessible on older Android hardware as well as newer phones. The current version is 1.5.13. I would still keep expectations modest regarding presentation: this is a focused reference tool, not the kind of app I would choose for elaborate social features or a large multimedia experience.
Its content rating is Mature 17+, which is worth noticing for households where app access is managed by age settings. That label fits the subject matter, but it does not change how I would use the calendar. I would treat it as an adult-oriented wine reference, not as an entertainment app for younger users.
The developer is Floris Books, and the app has reached over 10 thousand installs with a 4.6 average from 67 ratings. Those figures suggest a small but positive audience rather than a mass-market service. I would read that as a sign that the app appeals to a specific group of wine drinkers, not as proof that its method will suit every palate.
Who should skip it
I would skip this app if I want a searchable catalogue of wines, a place to store every bottle in my cellar, or detailed purchasing recommendations. I would also skip it if I am uncomfortable with lunar or biodynamic ideas and want advice based solely on conventional tasting information. In that case, the app’s central premise will probably feel distracting rather than useful.
It may also be a poor fit for someone who opens wine spontaneously and does not want a calendar involved. There is nothing wrong with that approach. Wine is often at its best when shared without preparation, and no app should make a relaxed drink feel like a scheduled test. The benefit appears only when the user enjoys observing patterns and planning occasional tastings.
Who will get the most from it
I think the strongest audience is an experienced wine drinker who already has bottles at home, enjoys comparing impressions, and likes small rituals. The app is particularly suitable for someone hosting occasional tastings, following biodynamic producers, or wondering whether timing changes the character of familiar wines.
It can also suit a curious beginner who understands that the calendar is an invitation to experiment, not a substitute for learning the basics. In that role, it may encourage more attentive drinking. The beginner should simply pair it with a good source on storage, serving temperature, glassware, and tasting vocabulary so that the calendar is not asked to do too much.
My verdict after building a routine around it
I see When Wine Tastes Best as a niche tool with a clear purpose. Its strongest feature is not complexity; it is the way it gives structure to a decision many wine drinkers normally make without thinking. Checking a date, controlling the serving conditions, tasting without leading the group, and recording the result can turn a vague belief into a personal experiment.
That workflow also exposes the app’s limits. It cannot tell me whether a bottle was stored well, whether my meal will overwhelm it, or whether I will personally enjoy its style. It does not replace a wine education resource, a shopping guide, or my own palate. The in-app purchase range means I would test the core experience first and spend only if the added material genuinely supports my habits.
My recommendation is therefore qualified but positive. If the idea of a biodynamic and lunar wine calendar interests you, this free app is an easy way to explore it without rebuilding your entire wine routine. Use it for meaningful bottles, compare its suggestions with your own notes, and keep the tasting conditions consistent. The best way to use this app is as a prompt for careful observation, not as a final judge of what belongs in your glass.
