Odd, odd, odd....

…and a testament to why making wine by formula and pre-conceived notion doesn’t work.

One section of one vineyard from Oregon. Own rooted, non-Dijon, old clone, dry farmed (whatever other currently trendy descriptors you want to apply): 23.7brix but 3.74pH, 3.8TA (lowest I have ever encountered), 40.5% malic, and a YAN (yeast assimilable nitrogen level — nutrients) of only 82 (also incredibly low).

Down to the Russian River Valley – another section from another vineyard. Much maligned Clone 23 (looks like Syrah, too large to make great Pinot), grafted, irrigated, hated by all: 26.1 brix, ph of 3.5, TA of 6.1, 40% malic, a YAN of 336.

This is why there’s a profession called winemaking.

Interesting. I have heard of such low acids but have yet to see it. Granted we are only about 25 percent in at this point.

We actually sought out Clone 23/Mariafeld (very rare in Oregon) last year from a vineyard we have been getting other sections from. Thought it turned out some of our most interesting wine last year. It is dark and structured and high in acidity but it was very compelling. Did not know it was loathed down there. Barely exists up here.
