November brings a question for anyone following wine around Grand Traverse Bay: what will the 2026 vintage taste like?

The answer starts with the grapes growers brought in, but the first clues come from individual vineyards and cellars. A picking date, a crop estimate and a finished wine tell different parts of the story.

What goes into the decision to pick?

Growers and winemakers track sugar, acidity and flavor as fruit ripens. They also consider the condition of the clusters and the weather ahead. When the forecast changes, the choice may come down to whether another few days on the vine would improve the fruit enough to justify the risk of waiting.

The intended wine matters, too. Fruit picked for sparkling wine is often brought in earlier to retain acidity. Grapes for a still wine may stay on the vine longer if the site and weather allow it.

What happens once the grapes come in?

Picking moves the work from the vineyard to the cellar. White grapes are typically pressed so the juice can ferment separately from the skins. Red wines usually ferment with their skins, which contribute color and tannin.

Fermentation is an early milestone. A winemaker may still have blending, settling or aging decisions ahead before a wine is ready to bottle. A November tasting room menu may feature wines from earlier years while the new vintage is still in production.

What would tell us how 2026 went?

A useful local harvest report would compare picking dates and crop volume with a typical year at the same vineyard. It would also explain how the fruit tasted at harvest and whether growers changed their plans in response to weather or fruit condition.

A report from one winery can tell readers a great deal about that property. Conditions and picking decisions can vary by site and grape variety across Old Mission and Leelanau peninsulas.
