According to some, there are two kinds of people in the world: those who wonder “how it works” and those who ponder “what it does.” The “it” could be a tool or a machine or a process. Put another way, some folks focus on how a final product is achieved while others focus on the various characteristics of the final product itself.

Since I’ve always been more of a “what does it do” guy than a “how does it work” guy, I will mostly sidestep the chemistry aspect of lees aging (proteins and enzymes and the like) and turn our attention to the final product. How does lees aging affect the wine in your bottle?

Lees aging is a winemaking regimen in which the juice is not cleared of its fermentation residue. After the yeast is introduced and the process of fermentation–converting sugar to alcohol–is complete, the dead yeast (lees) sinks to the bottom of the vat or barrel. At that point, the winemaker might decide to leave the juice in contact with this milky byproduct for an extended period. Depending on how much lees influence is sought, the juice can be stirred (a process called bâtonnage) to increase its effect.

For starters, lees contact will give the wine richness, depth, and warmth. It helps to smooth a wine’s rougher edges while adding complexity and breadth to the flavors and aromas. Lees aging might also help stabilize a wine by helping to fend off oxidation. Producers of “serious” wines from Champagne and Burgundy have traditionally relied on lees aging, but so have makers of sleeker, mineral-driven wines such as Muscadet and Galician albariño.

To me, there is a certain sweet spot when it comes to lees aging–when the technique takes place in stainless-steel tanks. The combination of stainless steel and lees contact gives a wine creaminess and texture without sacrificing acidity. It creates wines that are fleshy but still fresh, and it lends the wine a bit of weight and gravity while maintaining expressive, bright fruit. It offers some characteristics associated with wood aging, but with a more restrained touch.

I find that wines made in this style are often perfect for rich, shellfish-based dishes. At Paul Marcus Wines, we offer a wide range of white wines made in this steel-plus-lees style that are worth discovering, including three of particular note:

2019 I Favati Fiano di Avellino – Pietramara Etichetta Bianca

Fiano from the hills of Campania is perhaps the most esteemed white grape in all of Italy, and this multifaceted bottling offers ample proof why–especially when accompanying casarecce with rock shrimp in a spicy tomato-cream sauce.

2022 Benanti Etna Bianco

Made with 100 percent carricante from the eastern and southern slopes of Sicily’s Mt. Etna, this bright, gently smoky, beautifully balanced wine will shine alongside brinier dishes such as steamed clams and mussels in a lemon and white wine broth.

2020 Luis Rodriguez Ribeiro – Os Pasás

Predominantly treixadura, and filled out with small amounts of albariño, torrontés, and lado, this Galician stunner would pair well with gambas al ajillo (garlic shrimp) atop buttery white beans.

These three wines seem to have much in common: distinct minerality, lovely texture, and a subtle tropical vibe–melon and mango and such–along with a cleansing salinity. We are talking about dynamic, age-worthy whites that are much more complex and stimulating than your run-of-the-mill Sancerre and half the price of a comparable white Burgundy. As summer approaches and shellfish season begins, it’s the perfect time to get to know these charming white wines.

If you’ve ever found yourself answering the question, “Well, what d’ya want?” with “Anything but chardonnay,” we’d like a word with you. First of all, come on: The West Coast is having a chardonnay renaissance. From Southern California’s Santa Rita Hills to Oregon’s Willamette Valley, there are a multitude of styles, with as many fresh and chiseled examples as there are oaked and rich. In California, growers keep pushing the vineyards into cooler, windier places that limit quick ripening, while the Oregon versions have their own unique characteristics. They’re worth revisiting. Really.

Yet, if you’re set on trying something different, you should try fiano. The fiano grape (fee-ah-no) is native to southern Italy, with Campania being the epicenter. The story goes like this: Romans named it Apianum, “loved by bees,” and bees aren’t dumb. Fiano tends towards small berries and intense but not plentiful juice. The smaller quantity means that quality needs to be high to justify the labor.

In southern Italy, the summers are just as warm as they are here, and there’s no issue getting grapes to ripen (as there often is at higher latitudes or elevations). The challenge is maintaining the natural acidity of the grapes in the resulting wine. Some grapes fare better than others in this respect. Chardonnay, for example, thrives in cool pockets, but it doesn’t hold its acidity if the days and nights are too warm. You can add acid during winemaking, but that’s a poor substitute for perfect fruit. (Imagine an overripe strawberry sprinkled with citric acid–it’s still overripe.)

Fiano, native to a warmer climate, holds its acidity well. As California winemakers come to terms with a warming climate (2023 being an exception so far), they’re naturally drawn to grapes with a history of making quality wine from warm locales. Because of fiano’s low yields, it’s not the grape that will make growers rich, but climate change helps tip the scale.

At Paul Marcus Wines, we of course feature a world-class selection of Fiano di Avellino (fiano from its Italian home turf), but we also offer a handful of fiano expressions from California’s Dry Creek and Russian River valleys. Unti was ahead of the trend in planting Italian varietals in California (or replanting, but that’s another story), and their success must have encouraged the others. Unti’s fiano (as well as their vermentino, for that matter) shows the brightness and intensity of carefully farmed grapes. Unfortunately, the grape’s reputation for low productivity is true even in California, and they make tiny quantities. Gros Ventre is making fiano from a younger vineyard a couple hillsides closer to the coast, which dials it back a notch and shows a classy refinement. Cruess is working a 1.5-acre vineyard and somehow producing affordable wine.

These California plantings of fiano aren’t on the volcanic soils that dominate Campania, so the wines lack that suggestion of burnt rock. In addition, these California examples of fiano haven’t been given the heavy winemaking hand that many chardonnays have; no one is using new oak barrels to flavor the wine. In truth, these producers are still trying to tease out what California fiano tastes like.

Naturally, it’s worth trying both types of fiano (Italian and Californian)  to experience what’s gained and lost by the different soil types. For a survey of Campania’s finest, you can turn to sleeker examples by I Favati and Guido Marsella or richer styles like Ciro Picariello. We also have higher-end versions such as the Quintodecimo and the I Favati Riserva that are suitable for longer aging.

When pairing with food, fiano can handle dishes with a bit more acid than chardonnay is comfy with, so go ahead and squeeze that lemon or add a splash more vinegar. Any of the rotisserie chickens at Market Hall Foods or a variety of glazed fish dishes would also be excellent matches.

All together, we’ve got enough fiano in the house to keep you busy exploring for weeks. Come on by, and we’ll help get you started on your fiano journey.
