I am pretty sure the malolactic fermentation has neared its end. I will turn in another sample for analysis, but for now, I am concerned about leaving the wine unprotected. So today I am adding sulfites.
I used two different calculations, and will list them here:
First, the formula listed in The Winemaker’s Answer Book, by Alison Crowe, listed this one: (I don’t know how to underline yet, so the nominator is in bold, the denominator is below in italics.
(gallons of wine) x (3.785) x (free SO2 mg/L)
(1,000) x (.57)
I have about 72 gallons, so that formula gives me 14.34 g. Using Campden tablets:
14.34 g/ .44 (avg. wt. of tablet) = 32.59 tablets
Before I found the above formula, I had tried to wrap my mind around the math and figured the following:
72 gallons x 30ppm/gal = 2160 ppm total/(66 ppm/tablet) = 32.72 tablets.
So both formulas got me to about the same answer. I ground 33 tablets with a mortar and pestle until a fine powder and dissolved it in boiling water. It is cooling now, for addition shortly.
NOTE: Avoid breathing the powder or the fumes when it is mixed. This stuff is nasty and VERY bad for you, especially if you are asthmatic. I am, and even a small amount of exposure makes me feel drained and achy later in the day, not to mention the wheezing. Its yucky for sure.
But what it does for wine makes it worth the effort. When I take a whiff of the barrel, the fruit jumps out first. Syrah has a strong berry aroma and to smell it already, when such a young wine is not expected to have such a nose, is of great encouragement. I have high hopes for this varietal. The cool summer last year allowed for a slow, prolonged development of the flavor components not seen in a hot summer. Hope I don’t mess it up!
