Topic: Cleaning-and-Sanitation

There is indeed a combination of things I think could help, but it may take a little bit of elbow grease on your part. Two years is a long time for a

I’m happy to help clear up the argument for you. First, I have to say, “good on you” (as my New Zealand harvest interns used to say) for questioning what you hear;

Chemical and microbial stability measures must be taken after fermentation but prior to bottle aging to protect the wine from contamination and subsequent off-aroma generation caused by microbial metabolism. Learn the most common methods for achieving microbial stability, both during aging in the cellar and at packaging.

Wow, looks like you’ve got a serious case of “Ring Around the Carboy.” Thanks for sending in the picture, I always love it when readers do that because, especially in cases like

What’s the difference between cleaning and sanitizing? Cleaning refers to the manual removal of dirt, soil, and grime on an item or a surface. Sanitizing is the next step, which, when done

Q I have a question about sanitizing. I just mixed a fresh batch of potassium metabisulfite (1.5 oz. powder to 1 gallon water) to sanitize my equipment, and this latest batch has

My rule is no chlorine bleach in my wineries, never, nohow. Anything containing chlorine might contribute to the dreaded “corked wine aroma,” 2-4-6 trichloroanisole (TCA), in your finished wines. It can be

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

We can probably all agree that readying equipment for winemaking is not exactly a carboy of fun; nevertheless, it is an absolutely crucial aspect of winemaking. Reports of wine gone bad and,

I had a very interesting conversation with a couple of veteran winemakers at a guided wine tasting I conducted this fall. Together, they had made dozens of batches of wine, were using

I learned quickly during my early days of cleaning up after myself in the winery that a carboy brush is designed to spackle the walls, surrounding cabinets and the user with undesirable

An introduction to cleaning and sanitation for beginners.

Ah, yes, the joys of wood. We use wood in the winery for barrels and barrel-alternatives of course but, especially for the small-scale winemaker, wooden presses are still often part of our

One Step is a proprietary cleaning (and somewhat sanitizing) solution that is a secret formula; even the Wine Wizard will never know exactly what it’s made out of. From what I can

“They can make the difference between sound wine and spoiled wine.” Daniel Pambianchi Daniel Pambianchi was talking about cleaning and sanitizing when he put that maxim in Techniques in Home Winemaking. Home

It sounds like you took the right approach. A VA (volatile acidity) of 0.70 is not “out of this world” high, though it is a little elevated. Especially if this was a

Regarding ammonia (chemical formula NH3), I’m glad you brought the subject up. There’s a reason why we don’t use ammonia for sanitation in the winery and one acronym says it all: DAP.

Wine Wizard replies: Though ozone is an excellent tool for winery sanitation, the short answer is that unless you’ve got over fifty barrels of wine and sell it for a living, you

There are a couple of reasons I suggest we use tartaric or citric in the pages of The Winemaker’s Answer Book for cleaning and sanitizing purposes. First of all, acid is added

The better you plan for grapes to come in, the smoother the big day of harvest and crushing grapes will go. Do you have all of the equipment on hand and cleaned? Is the space cleared? Start planning now.

A Word From the Publisher And the Wine Wizard is……. “When will my fermentation stop?” “Why did my fermentation stop?” One thing I can count on as publisher of WineMaker magazine is

The Wine Wiz would first examine the press (especially the pressure-bearing bits, like the wooden side slats, the floor and any metal joiners) for wear and tear to make sure that, being

It is absolutely critical to have good winery sanitation as dirty equipment does nothing but invite bad-guy bacteria and unwanted yeast beasties to munch on our wine. However — there is a

You’re on the right track — it’s not a good idea to mix chlorine bleach with winemaking because free chlorine molecules can, if the conditions are right, contribute to appreciable levels of

You’re right to suspect that both the potassium metabisulfite powder and solution can lose their power over time. The solution, which you make by mixing the powder with water, is particularly unstable.
