OMG!

Orange muscat grapes, that is.
Vinomaker and I picked our Orange muscat (OM) today.  Well, what was left of it.  Looking almost like something that had escaped from my compost bin, Vinomaker had deliberately delayed harvesting the OM in the hopes of making a late harvest wine.  OM clusters are rather loose which generally reduces environmental favourablitly for Botrytis cinerea infection (unlike Pinot grigio clusters which are tight and thus susceptible to infection), so instead, dessication, as the result of an extended hang time, was the plan.  Coming in at 34.5 °Brix there is certainly plenty of sugar for Vinomaker to work with.
Although the fruit was quite unprepossessing, (OM never looks pretty as the grapes have a tendency to crack and amber as they ripen), the aromatics of orange skin and honeysuckle as we processed the fruit was absolutely delightful.  No wonder honey bees are attracted to this grape variety.

Dirty rotten scoundrels.

This time last week there were some rotten little scoundrels hanging around, up to no good, in the Pinot grigio block.
The above photograph of a cluster of grapes infected with Botrytis cinerea isn't that great (I could have fetched a better lens from the house, but I didn't).  However, the proficiency of the dessicating ability of this dastardly, necrotrophic organism is evident in the way in which it has sucked the living daylights out of the lower half of this cluster (the top half of the cluster looked perfectly normal).
Most of the infected clusters were discarded, but it's possible that some made it into the mix.  No biggie.
