William's California Wine Concentrates are made from 100% Central Valley varietal wine grapes, picked at their peak and gently concentrated with minimum heat (never exceeding 180 degrees F.) under vacuum to 68 Brix. Sugar has not been added, nor is sugar needed to make 5 gallons of full-bodied varietal wine.
The 192 ounces of concentrate included in each pack is enough to make 5 gallons of wine with an alcohol content of 13 to 14%. Contains sulfiltes, so you do not need to add them before fermentation. Sulphites are around 20 to 25 ppm before dilution, and after dilution, the juice right before fermentation has about 10 ppm sulfites. You may also have to add acid to balance this with your personal preferences as far as overall acidity goes.
Petite Sirah produces a wine that is full-bodied, dark and inky. Something like Cabernet, except with a bit less tannin.
NOTE: This includes concentrate only, and does not include yeast, oak, or other additives that may be needed to ferment 5 gallons of wine. For complete wine kits, see our William's California Wine Kits.
This concentrate is processed with minimal heat and is unpasteurized. Refrigeration is REQUIRED on arrival, and shelf life once received is 8 weeks if stored refrigerated.

Q: How much concentrate are in the 5 gallon concentrates? I see it in oz but what would it be in liters or gallons? Thanks!
A: 1.5 gallons.



Petit Syrah
I very much appreciated ordering through Williams Brewing. There was a mixup on the Petit Syrah order, but when I called them, everything was set right (and more so). I'm just through the primary fermentation and it is tasting good at this point so I am very positive I will get a good wine from this and look forward to ordering again.
Petite Syrah
've been an award winning home winemaker for over 30 years and have won numerous awards from the Marin County Fair and Sonoma County Harvest Fair amateur wine contests from wine made from fresh grapes. Having made grapes from concentrtes that taste like they're cooked ('cause they are), these stable concentrates are the next best thing to using fresh grapes that yield first class wine. Highly recommended
Amazing
Everyone loves it, I will make again. Delicious
Aged Well
I purchased this kit 2 years ago and bottled 18 months ago. I have had a few bottles along with each tasting better. Now after 18 months it is excellent. I have had good luck with all of William's reds and have found it is best to age them at least a year after bottling.
Petite Sirah concentrate
I've fermented the Petite Sirah, Pinot Noir, and several others. They make a good wine. I do age them for approximately one year before moving to the tap. Yes, I age my wine in stainless kegs and once ready I put them on tap. Way easier than bottling and takes up much less space in the wine cellar. A good product at a good price point.
