Light Strike in Wine?
Michael Beudry — Newtown, Connecticut asks,
I’ve been a home/ hobby winemaker for some years but last year I took a big leap with three new demijohns. The increase in volume caused me to move my aging wines to a part of the cellar where there is a small south-facing window. While the carboys and demijohns are in a drop-cloth tent, and there is a piece of paper covering the window, indirect sunlight still comes through. Question, can this indirect light affect the aging of the wine? In particular, any impact on the color profile? Instead of a deep red/purple color, it is bright but a lighter ruby shade. Any thoughts or concerns?
