When you have a vertical wine tasting you will have one varietal of wine from the same vintage. This means you might have the same wine from different years; 1999, 2000, 2001, etc. The most common purpose of tasting wines like this is to get a good idea of a certain wineries style and composition. You can also get an understanding how the different weather patterns affect grapes during certain years.
When a horizontal tasting occurs you will use the same wine from many different producers. This type of tasting will allow you to determine which wineries you think produce the better wine. This wine will be from the same year and the same type of wine but from different wineries.
When you hold a tasting flight you will have many glasses of wine out for the tasters to test. Next to each glass of wine you will have a card including the specifics of the wine; winery, geographical demographics, type, and more. Some flights include up to 50 glasses of wine to be tasted.
This gives a taster an idea what types of wines come from certain parts of the world and more. You can also get a good idea of the different tastes of the different types of wines when you taste wine through a flight.
Old World versus New World Tasting
Many people enjoy this type of wine tasting. The Old World according to wine enthusiasts is considered to be countries like France, Italy, Austria, Spain, etc. The New World is North America, South America, South Africa, New Zealand, and Australia.
The reason these countries are considered to be the New World is because they are new to the wine producing industry and late starters. However, these countries are significant in producing wines.
Many people like to feature the same types of wines from the old and new worlds to determine which they like better. Some people like to do a horizontal or vertical method with this also. There are many ways to mix it up so you can make your wine tasting successful.
