💡Wine Serving Tips
If you have three bottles to serve eight guests, and it’s dinnertime… Don’t freak out! You start feeling anxious because people drinks at different rates.
Using the calculator ensures that there will be no guesswork in your beverage budget. Your hunches become an actual shopping list before you walk out the door.
How to Buy the Right Amount of Wine
In theory, that should provide five five-ounce servings per 75ml bottle. In practice? That’s the problem (parties aren’t theoretical vacuums). Double pours occurs regularly as do spills. And guests will change drinks throughout the meal.
To accommodate such estimates, the tool asks you to set your service mode at the start of the experience: Is it a long dinner with lots of red meat? Or is it a series of small tastings from several different bottles? One requires deep pours from few source; the other small samplings from many.
Why does it matter? Because if you get the pace wrong, you’ll run out too soon … or else you’ll pay for unopened bottles. All guests aren’t wine drinkers. Wine isn’t for all, some drink cocktails, others beer, still others water. Don’t waste your money by assuming all guest want reds: use the calculator to make it real.
Wine is a heavy liquid that leaves sediment and spills. Include 5-10% as a margin for error and be realistic. No one likes to scrape out last bit from a carafe while explaining they’re out of bottles.
The pour size also varies depending on style. For example, dessert wines is heavier (in taste and density) and typically demand smaller glasses. Foamy cocktails like sparkling wine gets smaller pours at toast time, typically three ounces. These distinctions are broken out on the reference tables by bottle size.
They illustrate not only how much larger a magnum will be but also its greater size: two regular bottles equal one magnum; hence, twice the volume and twice the prestige. It’s also a handy detail for hot weather affairs, a large format bottle stay cooler longer.
The key is realizing what it’s measuring. It’s not about ounces but instead how much stuff flows through (which is why it’s called Flow). Enter details of your event (length, number of guests) and it calculates how often refills might be needed.
If it’s a two-hour cocktail party, people will get through more drinks then if it’s a four-hour seated dinner with food in their stomachs and hands. That’s money-savings. It keeps you from buying too much just because an event is longer. Believing that a longer event equals more alcohol consumption are a rookie-planner mistake.
Round up on bottles. Don’t ever round down. It is worth the cost of having an extra bottle on hand. It would of been better than being embarrassed by offering watered-down wine or awkwardly asking someone to pass a glass around. Your buffer is included in the rounded total given by the calculator. You’re given a solid number to jot into your notes.
From there, you can go shopping comfortabley, no stress involved. Wine is supposed to unite people, not cause us to worry about how many bottles we’ll need. Pour wisely and let the wine take care of the rest.
