Eat beforehand – Even if your tour includes a picnic lunch or lunch at one of the wineries, the alcohol levels can often add up before you know it.
Avoid coffee and chewing gum – Especially right before wine tasting, as it will affect your palate.
Drink water – Your tour guide will have water. Staying hydrated is critical to enjoying your wine tasting experience. Drink as much water as wine.
Avoid anything that interferes with your sense of smell – No heavy perfumes, colognes, or shaving lotions. Smokers beware: remember to consider that the smell of smoke could affect the tasting experience for you and others.
Dress in layers and comfy shoes – Temperatures can vary from cold mornings to sunny afternoons. Take a lightweight jacket along and closed toed shoes are helpful for the dusty trips out to the vineyards.
Bring a cooler – You don’t want the wines to “cook” in the vehicle, which is possible even on a cool day. Wine is easily damaged by heat and can start to spoil if it gets above 75° F. The wine you loved at the winery may not taste the same when you open it at home.
