Remove A White Film on Carboy

The New Need For Sanitation

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


Use Of Bleach In A Winery

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


Chlorine In My Wine

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


Wine Press Mold Growth

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 Cleaning

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

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


Sanitation Sanity: How often should wine equipment be sanitized?

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


What is the best way to store plastic fermentation tubs and keep them clean?

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


Is it possible for the potassium metabisulfite powder I use for sanitizing to lose its strength over time?
