Wine Wizard

Oh dear. I fear that your wine has been contaminated not just with chlorine, but with the dreaded TCA, or tri-chloroanisole aroma defect. Also known as the “corked” aroma, TCA is the

You definitely want to water down that high-sugar juice before you pitch your yeast. High Brixes lead to high alcohols, which lead to yeast that just can’t complete a fermentation. Stuck fermentations

I’m with you. If I was making a Port-style wine and it was 20% alcohol and 100–150 g/L residual sugar (10–15%) I would forgo the potassium sorbate altogether. I am not a

I’ve seen a few of these kinds of articles (ahem, I mean advertisements) floating around on the internet and it always results in an epic Wine Wizard “facepalm” upon reading. For starters,

Those are all great questions, let me see which order I’ll tackle them in. Firstly, we discuss corks for the most part on the pages of WineMaker Magazine not because they’re the

You are more in the right here than your brother; when buying wine at a restaurant you really just smell and taste the wine. If the wine smells and tastes fine to

Good for you for branching out. Apple cider has astronomically increased in popularity in the United States in the past few years and I see an increasing number of wineries trying their

That’s too bad that you added more copper sulfate than you intended to. Copper is an effective, legal, and ancient (the Romans knew about its curative powers in winemaking) tool for reducing

That’s certainly an interesting question and one for which the short answer is “no such equation exists.” The longer answer attempts to help explain why, even though you think you should have

Funny you ask this question as I’ve just now got three tanks full of 2016 Monterey Pinot Noir rosé fermenting in the winery. White Zinfandel, contrary to what some folks think, is

Not knowing any more information than you give above, it’s tough to make specific recommendations so I’ll start with the general ones. Whenever you suspect VA (volatile acidity, or the production of

In the old days we would use paper chromatography to monitor the completion of malolactic fermentation (MLF). We dotted little drips of the sample wine, along with liquid standards of malic and

Ever open a bottle of red wine you’ve lovingly saved for 20 years only to be disappointed as a brick-orange liquid followed by a brownish sludge falls into your glass? The issue

Thanks for clarifying your question a little bit. I am glad to hear you regularly top off your barrels, it’s a practice all of us need to do. Alcohol and water definitely

I’ve certainly had the odd leaker (or three) but I’ve never experienced trans-stave leakage of the scale that you describe. Before I delve any deeper, I first of all would like to

Certainly you can try to pasteurize (heat at a certain temperature for a certain amount of time) your wine if you like. Many foods and beverages (like milk) are so heat treated

In my day job in Napa, California (as Winemaker for Garnet Vineyards as well as other consulting projects) I bottle plenty of “partial ML” Chardonnay every year and love the style. In

To shed light on your query, the Wine Wiz consulted the Winemaking Magic 8 Ball™ and the answer that floated to the top was, “Outlook not good.” If your 2010 Zinfandel still

There’s nothing like a wine with what I call “the elbows sticking out” to ruin one’s mood. Especially frustrating is when one has followed a recipe or kit instructions to the letter

Though tough to define as it can smell different to everyone, there is unfortunately no wine lab analysis panel you can run that says, “Yessir, you’ve got an over-abundance of Ivory Soap

The short answer is that yes, I would absolutely cut down on the amount of clarifying agent you use if you don’t have enough wine volume for the recommended 5 gallon (19

Congrats for breaking out of the mold and taking it upon yourself to adapt a recipe to your own preferences! I always love it when readers, and my own winemaking buddies, take

Sounds tasty to me! I love a dry (or even off-dry, maybe with residual sugar of around 5 g/L), crisp Muscat wine. Historically, Muscats have been used in many wine types, from

The fun of filtration! I’ll deliver the bad news to you and my readers first by telling you that really no matter how tight of a pore size you use to filter

Just like I would not let a buddy of mine do any Brettanomyces beer-brewing experiments in my winery, so should you not do Kombucha and wine together in your kitchen (or garage)
