Finished boiling up batches #5a (propane boiled) #5b (wood boiled) and #6. That added 8.6L in bottles now settling on the counter. I've never boiled that much syrup in so little time. Batch #6 has that unmistakable rich maple flavour that I had never been able to achieve in past years. I hope that means that the sap I'm now collecting will continue to yield more of that great taste.
