It is very common during harvest for our users to add volume (such as bleed or saignée juice) back into a different lot that is still in weight. Other users may use an already fermenting juice lot to inoculate a lot in weight. If you attempt a Bleed/Saignée action to blend into a lot in weight, or otherwise transfer volume into a lot in weight, you may see an error like this:
or this:
InnoVint does not allow blending of lots when the lots are not both in weight, or both in volume.
Here are some possible workflows to help:
1) If you are bleeding juice straight into a lot on skins, you can calculate an equivalent amount of weight for the volume, and complete a weight transfer instead. Use a custom action or task to record the actual date and volume of the bleed:
EX: If you are bleeding 100 gal of Lot X, with an estimated yield of 150 gal/ton, into Lot Y, complete a weight transfer for 0.67 tons of Lot X into Lot Y.
This will allow you to maintain composition, and would automatically adjust the yield of the lot on skins.
2) If you are adding pressed juice or wine back to a lot in weight, consider whether you'd like both lots showing as either weight or volume in inventory and then choosing the Process Fruit action that best fits both lots. For instance, if you plan to do cap management on the blended lot, you might choose to leave everything in weight (including the pressed lot) and record a Custom Action to note the volume and date of pressing for the lot (or portion of the lot) that was pressed. Complete a weight transfer instead. You would then be able to use a "Drain and Press" action on the blended lot.
3) If you've already processed and bled lots, you can also keep the bleed in a "phantom" vessel with a similar lot code to the lot in tons (perhaps add a -VOLUME, or -BLEED suffix), and then blend them once they are both in volume. Be sure you alter the expected yield via the Lot Details page of the lot in weight so that the additions calculated by InnoVint are accurate. You can use a Custom Action/Task to track the point in time where the bleed actually was added to the lot in tonnage, in the same way that you would complete water addition (here is a link to those step-by-step instructions). Try using tags to track both lots and remind yourself to blend the lots in InnoVint.
4) If you are not concerned about tracking the added volume as an element of your lot composition, you can also consider simply completing a Custom Action or Task on involved lots to record or request the action without impacting yields, composition or volume.
