Michiganders have a way of showing their hand. They have a technique — a tradition, really — of lifting their right hand and pressing their left index finger into a spot on their palm to give you, the Michigan-geography-challenged, a lesson in what’s where.

The state looks like a mitten (thus the palm, with closed fingers and a slightly extended thumb), sitting solidly in the Midwest and virtually surrounded by massive, freshwater lakes. While you could point to several spots on the mitten to show where vineyards and wineries are, most are close to the western and northern shorelines — from the outside of the wrist up the pinkie and around to the tip of the middle finger. These vineyards optimize Lake Michigan’s moderating effects, which extend the growing season and translate to slower grape ripening and acidity retention.

There are five regions in Michigan that have been granted official AVA (American Viticultural Area) status. In the southwestern tip of the state (in the palm-geography game, near the outer wrist) is the Lake Michigan Shore AVA, which includes the smaller Fennville AVA.

At the tip of the pinkie, there are two AVAs — Leelanau Peninsula and Old Mission Peninsula — and more than half of all Michigan wine comes from this area, which is anchored by Grand Traverse Bay. (Don’t confuse either of these with Michigan’s Upper Peninsula, the landmass that reaches clear across the top of Lake Michigan and connects with Wisconsin; the wines of Michigan come from what is officially known as the Lower Peninsula, aka “the mitten.”)

The final AVA has the most mirthful of names, Tip of the Mitt, and I don’t need to tell you where that one is; the name says it all. I tasted scads of wines from Leelanau Peninsula and Old Mission Peninsula, both of which extend north from Traverse City, and a baker’s dozen of noteworthy bottles are listed below.

Michigan produces a lot of wine, and not all of it is made from fine wine grapes — or even grapes. Various fruits are used (like cherries), along with some native and hybrid grapes, but close to three out of four bottles of Michigan wine come from European wine grapes. Among the most popular are pinot blanc, pinot gris (also called pinot grigio by some Michigan winemakers), sauvignon blanc, riesling, gewurztraminer and chardonnay on the white side; or pinot noir, cabernet franc and merlot on the red side.

Michigan’s first commercial winery was established in 1868, but the state’s wine region has experienced highs and lows through Prohibition, World War II and a number of developments through the ’70s. Today, more than 140 wineries call the state home, and its vineyards reach across more than 3,000 acres. Some Michigan wines are available in retail stores outside the state, and most can be ordered directly from the wineries.

Below are notes from a recent tasting of wines from Michigan’s Leelanau Peninsula and Old Mission Peninsula. The wines are listed by wine style — sparkling followed by white and red — in ascending order, according to price. They’re not cheap, but included in the price is your ability to surprise your guests with the phrase, “This next wine is from Michigan.”
