Diam Corks

DIAM Corks for HafnerWinemaking is science driven and hence an ever-evolving profession. Through experimentation, we always strive to improve our techniques, processes and ultimately our wine. Cork is a natural product; one that we consider 100% sustainable. However, there is a component (trichloroanisole or TCA) that can impart a musty quality and hence ruin the wine. We call this a "corky" wine. Cork producers have worked hard to eliminate TCA or at least mitigate its impact. In the quest to do so, a French company named Diam has created a new technical cork. After many trials and conversations with colleagues, we decided to move from "punch corks" to Diam "technical corks".

Comparing Main & Reserve Chardonnay

Main and Reserve ChardonnayWe make two different Chardonnays from the same vineyard - our main and Reserve Chardonnays. Patrons often ask why we do this and what the difference is between the two wines. Generally speaking, the main Chardonnay is a blend of California and French winemaking techniques that yield a bright, crisp, citrus driven wine. In comparison, the Reserve Chardonnay is all barrel fermented, goes through malolactic fermentation and is aged "sur lies". This wine is more complex with flinty aromas and a soft, round palate. Here, we dive deeper into the differences between these Chardonnays.

Fire Preparedness

Fire Prevention at HafnerSince last year's Kincade Fire reached our hillsides, threatening the winery, vineyard and homes, we have taken many actions to prepare for future fires. Fire officials suggest two main goals for preparing for a wildfire: 1. Create “defensible space” and 2. “Harden structures”.  We took these recommendations and made several changes that we hope will help when the next wildfire comes our way. California has experienced devastating fires these past years. Five out of the six largest fires in California history occurred just this year. As the climate continues to become drier and hotter with stronger winds, we can only predict that massive fires will continue. All of us on the West Coast and in many other areas are faced with this annual challenge. Together, hopefully, we can work to make a difference.

Decanting Wine

Decanting Cabernet SauvignonDecanting (pouring the wine from the bottle into another vessel, typically a decanter) is a simple, but careful process. It can be intimidating knowing when to decant a wine and when not to. Here I share three reasons for decanting a wine and hopefully they help shed some light on any confusion. Everyone's tastes and opinions are different, so my goal is to share with you what I know about decanting and aerating wines as well as the science behind it. Then it's up to you to have fun and do some experiments tasting the wine as it aerates in a decanter.

How Chardonnay Ages

Hafner Chardonnay Vertical TastingOften, I am asked “How long do you age your Chardonnays?” And my answer is always a bit complicated. I do say that our Chardonnays can age easily for five years from the vintage date, but wine is a personal preference. It’s like asking “do you like your steak rare or well-done”; only you know what you prefer. Wine is a bit more complicated than beef, but there are some basic tenets that you can apply and decide what you prefer. Chardonnay, when young, has a bright, lively fruit driven quality that is quite enjoyable. As it ages, the bright, crisp citrus notes become more complex and developed.
