CV Spouts improve Sugar content later in season?

[devils11217]

I know CV spouts are the way to go to improve season long higher yields. My question is does CV spouts increase your chances of receiving higher sugar content later in the season. my rational on this is if bacteria is unable to get back into the tap hole and bacteria feeds on the sugar.... in theory sugar would only be exposed to bacteria while if flows in the laterals to the mains. I would think would vacuum this would limit this exposure as well. Tim Perkins or someone with a degree higher than my street knowledge shed some light onto my crazy thought? It would be nice to get 2 % sugar vs 1.1 during late march.

Don't think so,my theory is there is just so much sugar in the cells in the maple tree and the more water from the ground passes through them,cells don't have as much sugar in them as early in season they are full of sugar.

Mostly correct, although each freeze-thaw cycle also stimulates conversion of stored starches to sugar for a while at least. I doubt that CV would have much of any discernible effect on sugar content. Microbes do consume sugar, but the sap isn't hanging around long enough to experience that much of a reduction in total sugar....it is more of a conversion of sucrose (12-carbon sugar) to invert sugars (glucose and fructose, 6-carbon sugars which caramelize far easier than sucrose...which is why it makes darker, stronger-tasting syrup) that is taking place.

I will point out that while many people thing the sanitation effects are mainly about getting more sap later in the season, much of the effect begins far earlier. We start to detect differences in sap yield about 1/3-1/2 way into the season. They are small at that point, and get larger and larger as the season progresses as sap yield in the less sanitized systems drop off and those in the higher sanitized systems keep going. So it isn't that you're getting more, but lower quality sap only at the end of the season. You are actually getting more good quality sap throughout 1/2-2/3 of the season as well.

thanks Dr Tim for a better explaination,that to meseems the best way to explain it to the general public,i understand the sugars,now got a much better concept,oy attended your sap run seminar in Verona
