They say winemaking is part science, part art. That expression may ring most true when it comes to fermenting red wines. While there have been numerous studies and much research regarding the
When I was assigned the story detailing the decisions that come up during red wine fermentations, I began to block out the options and decision trees that occur before, during, and after
Wine is far more than alcohol and grape juice. What makes the magic? Fermentation is the star. I like to drink white wine, I like to make white wine, and I like
The benefits of cold soaking are debated among winemakers, but those who subscribe to the technique of keeping (usually red) grapes cool for a few days prior to fermentation swear by it.
Not properly controlling the temperature of your grapes, must, juice, or wine can have lasting impacts. Learn when and how to take control.
I applaud you for trying fresh winegrapes in your home winemaking, you’re lucky that you are (relatively) close to a fine winegrape growing area like the Santa Ynez Valley. I grew up
Well, according to specific gravity, your cucumber wine (sounds refreshing) is dry. For RS-dry (residual sugar dry) you want to look for an SG of 0.992 and 0.996 on your hydrometer. If
Malolactic fermentations tend to stall, or not catch on at all, due to these seven most common factors: High alcohol: Over 14.5% and most strains will go through slowly. Over 15.5% and
A fermentation is “stuck” when it fails to reach the desired conversion level of sugar, usually coming to a halt somewhere below 10 °Brix. It does not refer to a failure to start,
You are absolutely right that most wines, especially those that are inoculated and have favorable conditions, will go malolactic (ML) complete within six or eight months of harvest. Even if your area
That’s a great question with a very simple answer. You should not add postassium metabisulfite (SO2, or sulfur dioxide) to your wine between primary and secondary fermentation. Because the SO2 will inhibit
Careful attention must be paid to fermentation to achieve great wine. We gathered experts from four different yeast laboratories to glean advice on selecting yeast strains, co-inoculation, optimal fermentation conditions, and more.
Fermentation is a chemical reaction that takes place when yeast turns sugar into carbon dioxide and alcohol. Obviously, this is a critical part of the entire process. A yeast cell will turn
Malolactic fermentation (MLF) is a secondary fermentation occurring when malolactic (ML) bacteria become active in the presence of malic acid. Bacteria may be present naturally in fresh grape juice or wines. It
Many hobby winemakers believe that fermentation temperature control is beyond their reach — but this isn’t so! Discover how to keep temperatures in the proper range.
There are so many microbes that can produce tiny bubbles in new wines that perhaps your question should be, what microbes will not produce tiny bubbles in dry must? Everything from (of
It’s hard to tell exactly what may be the issue because wines that just finish fermenting and are so young often have “funny” smells and do indeed not smell like the finished
There are temperature ranges advisable for fermenting all wine styles, but how does each end of that range affect the aroma, taste, and body of your wine?
I’m a little old school when it comes to malolactic fermentation, but it’s always served me well. There are some winemakers who try to get a jump on malolactic (ML) completion and
Oak, Glass, Plastic, and Stainless Steel wine container must be sturdy enough for the purpose and not likely to introduce negative changes to the wine quality. Size is important, depending on the
Grape juice is a pretty tough environment if you’re a yeast cell. The pH is low, there’s high osmotic stress (stress from the environmental conditions being such that the flow of water
For those that would like to start getting a better handle on the fermentation temperature of their wines, you’ve found the right spot.
When setting out to make wine from grapes, one of the first major decisions is what you will use as a fermentation container. For most winemaking, you will need a primary fermenter
