Making your own wine is satisfying and easy. As long as you ferment great juice, keep everything sanitary, and give it enough time to age (3 months or more for whites, 6 months or more for reds), you will get great wine.
Here at William’s, we have developed our William’s California Wine Kits with this philosophy in mind. Our Kits include 192 ounces of pure California varietal grape concentrate, condensed at temperatures that never exceed 180 degrees F. from Central Valley wine grapes picked at their ripe peak in the late Summer and early Fall. To complement the varietal juice, specially selected dry wine yeast is included. Unlike many wine kits featuring added sugar, this 192 ounces of pure concentrate is all that is needed (except for the yeast and addtives) to produce 5 gallons (24 bottles) of varietal wine.
Riesling is a grape that has adapted well to California, and produces a wine with a fruity, floral character. Riesling can be excellent after only 3 months of aging. Click

Q: If I can't make this right away after receiving the kit what is the best way to store it?

I started this Riesling wine kit in February 2021. Thirty days later I completed the stabilization and clarification steps without issue. In May I tasted it and gave it good marks for clarity, color, aroma, and taste. I bottled the wine in May and tasted it again in October. It still gets good marks for clarity, color, aroma, and taste but the mouth feel is ‘thin’ and has an unpleasant aftertaste that is hard to describe. I’ll taste it again in a couple of months and adjust my score if appropriate, but for now I have to give it an average rating. The alcohol content seems uncharacteristically high for a Riesling approaching 14% ABV.

Wonderful flavor and as age enhances flavor - cannot find any that are better. Had a small gathering and Everyone tasted and raved about the flavor.
