Racked 2009 Syrah

gardner — Fri, 25 Jun 2010 16:01:08 +0000

Due to sloth and some personal issues over the last few months I didn’t get around to racking the Syrah until two days ago. It was keeping me awake at nights, so I sucked it up and did it. It went well with only a little spillage and ended up with a barrel plus a half [...]

2008 Zinfandel Lab Results

gardner — Fri, 12 Dec 2008 16:55:01 +0000

Here are the results of the latest lab test for the 2008 Zinfandel:

Malic Acid 83 mg/100mL

pH 4.16

Titratable Acidity 0.605 g/100mL

Free SO2 None detected

Total SO2 3 mg/L

I fear ML is stuck as it needs to get down to 15-30 mg/100ml. I am going to try adding some fresh cultures. Also the pH is too [...]

Conflicting Brix

gardner — Thu, 18 Sep 2008 16:37:58 +0000

A day after pitching the yeast I check the temp and gravity. There is activity already, temperature was up 3ºF even though it was a cold night (46ºF outside). The weird thing is that I am getting a higher reading of 26ºB as compared to the the two other readings both coming out at 24.5ºB. I [...]

2007 Initial Harvest Numbers

gardner — Tue, 02 Oct 2007 14:35:53 +0000

I re-calibrated the pH meter and did my best with the titratable acid test. I might send the G&M Syrah in to Vinquiry to double check the pH. The Syrah is so much darker than the other two.

- Cabernet, Syrah, Merlot

“Gardner’s Block” Merlot 200 lbs Brix: 25.00 pH: 3.65 TA: 0.82% Potential alcohol: 14.75%

“Gardner’s Block” Cabernet 160 lbs Brix: [...]

2006 Merlot Lab Tests

gardner — Thu, 20 Sep 2007 16:22:52 +0000

I pulled off 300 ml to send to Vinquiry today. After racking I took the left-overs and ran my own lab tests on it. Here are my numbers, they seem a little weird.

TA = .65% pH = 3.66 SO2 = 45 +

The acid should be higher considering the pH and SO2 seems high as well. Now we get [...]
