The Wiz offers advice on maximizing color extraction and shares the impact temperature plays in it. Plus: How cold is too cold to age wine, why a wine may require long decanting times to open up, and techniques for taming tannins.

You’re absolutely right to be thinking about how temperature affects the color of your final wine, especially if you’re fermenting outdoors. How cold or how warm a fermentation is plays a huge

Greetings from right here in Napa! Like you, I bundled up a bit more this past winter and kept a close eye on cellar temperatures — it was definitely one of our

Congrats on crafting a bold Bordeaux-style blend with strong aroma and flavor! That’s no easy feat, especially when you’re juggling the powerful personalities of grapes like Cabernet Sauvignon, Merlot, Malbec, and Petit

That long decant time you’re noticing — needing about three hours to “open up” in the glass — is something many winemakers (myself included) have encountered with young red wines, especially those

A 40-year-old Cabernet Sauvignon that’s now as white as a ghost? Oh no! The Wine Wizard gets to the bottom of this spooky phenomenon and also discusses the pros and cons of bottling wine in swing-top bottles and how to combat bottle shock.

A. Ah, the joys (and occasional shocks) of rediscovering long-forgotten bottles! Your 1984 Australian Cabernet, now ghostly pale with all its color settled at the bottom, is a fascinating case study in

Your switch from natural cork to swing-top bottles is an entirely reasonable one given your storage constraints, and you’ve taken the right steps to ensure your wine is kept in a stable

Sounds like you’ve been bottle shocked! That, and you are experiencing some post-bottling sedimentation. You’re not alone in this, my fellow winemaker. Many a vintner, professional and amateur alike, has been surprised

The Wine Wiz offers her wizdom to bring a tart wine into balance, as well as ways to add body to a wine and why non-alcoholic wine production should be left to the pros.

With the increasing popularity of non-alcoholic (NA) wines, it’s no surprise that home winemakers are wondering if they can craft their own. The short answer is that while it’s possible to remove

Enhancing the body of your grape wine with bananas is a time-honored technique among home winemakers. Bananas are rich in complex polysaccharides — long-chain sugars — that, when extracted, can impart a

Your wine’s sharpness after adding tartaric acid is a classic case of how pH and perceived acidity don’t always play by the same rules. You did the right thing for microbial stability

While there are a lot of urban myths surrounding winemaking, the one about racking under a full moon isn’t totally hogwash. Plus, what to do when your wine begins turning to vinegar, the specific gravity of a “dry” wine, and tips for making wonderful white wines.

While there is so much hooey out there about “don’t rack during a new moon” or “only bottle during a full moon,” the winemaking dictum you mention is based, at least loosely,

The quick and dirty answer to your question, and quite possibly not the one you want to hear, is that you’re best off dumping your vinegar bottles of wine down the drain.

I definitely think you should wait for the fermentation to complete and then rack and add sulfur dioxide. I doubt you’ll have to add any sorbate to protect against a re-start fermentation

It seems like you’ve found something that works for your red grape winemaking — making additions based on your 36-lb. (16-kg) lugs of grapes. Your estimated yield for grapes fermented on the

You’re a reader after my own heart! Yes, the wine industry seems to have made life more difficult for itself by inventing (and continuing to promulgate) a litany of “to dos” and

Bravo to you for doing bench trials! If you’ve read my columns over the years you know that doing bench trials — that is, testing a wine treatment on a small scale

I’m glad you wrote in this question. It points to the importance of thinking about our wines in the big picture sense (not to mention the importance of double checking before making

If you sometimes prefer your red wines served a little on the cool side or are not afraid of buying high-end wines with screw cap closures, you aren’t alone! The Wine Wizard shares her “consumer myths” that need to be debunked. Plus, the role your yeast choice plays on malolactic fermentation, and advice on adjusting a high-pH juice.

The pH of these grapes do seem high. For California grapes, I like to see whites in the 3.30–3.45 range and reds in the 3.45–3.65 range when picked. However, many of our

You are really onto something here! Water is added to recipes for many different reasons. If you’re making a wine with flowers or dry fruits (like dandelion wine or elderberry wine) you’ll

Interestingly, even though your heat summation units are low, you are close to the Pacific Coast so I am guessing your winters are mild. European grapevines (Vitis vinifera) grow at a minimum
