A winery tour can help you understand how the wine is made, and reveal a lot about the winemaking philosophy. When a tour guide pauses to explain a specific production method or piece of equipment, they provide insight into what’s most important to the winery’s process.
As winemakers around the world work to grow consistently healthy and ripe fruit despite a changing climate, their winemaking approach has become less about correcting and adding flavours. Touring cellars for the past 25 years, I’ve witnessed an ongoing transformation for the best producers to capture authentic taste that comes from their region.
Bottling lines and gleaming, refrigerated stainless-steel tanks used to be featured attractions for wine tours in the 1980s and 1990s, showing how much the producer prized scrupulous hygiene and quality assurance. These are capital investments in equipment that create efficiencies and allow precise control of the winemaking process, but they don’t leave wine lovers with romantic associations of wine being bottled as poetry.

Any tour today continues to spend significant time in barrel cellars, but the stacks of smaller oak barrels and larger-format wood vessels have been overshadowed by more fashionable alternatives, such as concrete eggs and clay amphorae, that are being embraced by cutting-edge producers around the world.
Oak barrels continue to play an important role, supporting the character of many of the world’s best white, red and even sparkling wines. Wine geeks can get “grain-ular” (a la granular, the overused business buzzword) on the nuance that different types of woods, from different forests, with different toasting levels and barrel shapes can bring to a finished wine.
Barrels containing the same batch of wine can end up showing different intensities of aroma and flavour, which gives winemakers a broader spectrum of flavour to blend before bottling.
To the untrained eye, however, a barrel is a barrel is a barrel. Point at some Humpty Dumpty shaped containers in the corner, there’s a story to tell. Likewise, a row of terracotta pots, modelled after ones used in the ancient world, is an invitation to explain how these winemakers are adopting a back-to-the future approach in the cellar.
Unlike oak barrels, these vessels don’t add woody flavour or tannin to the wine. The earthenware and concrete composite containers provide temperature stability for fermentation and aging. They are also porous, allowing oxygen to help build texture and stabilize the wine.
The resurgence of clay, terracotta and concrete fermenters is part of an increasing thirst for wines with flavour and authenticity. The best expressions offer intense and pure fruit character and rich textures. Considering the investment to purchase and labour-intensive care to maintain, you’re sure to hear about them whenever present in a wine cellar. Hopefully, you’ll also be able to taste the results of that effort in the glass.
