Measurements II

In an earlier post I estimated that a 240 gallon t-bin completely filed with must yields 165 gallons of wine. I've been trying to monitor this throughout harvest and so far I'd say 165 gallons is on the low end. In a recent pressing I estimate we yielded 195 gallons of clear wine/T-Bin. That seems high, so let's call it 190 -- still significantly more than 165. The data I'm seeing makes me want to estimate 180 gallons of wine from a full T-Bin. This is an important measurent when determining acid and water additions to the must. For adding yeast, nutrients, and So2, I believe you measure total volume including solids, so this ratio is not important there.

180 gallons means that the grapes are about 25% solids and 75% liquid.
