Sunlight and Barrel Storage

Recommended Posts

I am closing in on selecting a property for a startup craft distillery in Northern CA.  The favorite one is two buildings on a single commercial lot. One would be the barrel storage building the other would house the distillery operations. The barrel storage building is brick surrounded with windows (see the attached image).  I assume the precious liquid within would not be impacts by getting hit with sunlight through these windows, but wanted to get some feedback from anyone with knowledge on this.  Thanks!

In a reasonably cool area I believe a bit of sunlight on the barrels will increase the rate of "ageing"

Hotter during the day, cool at night causes expansion then contraction of the air in the barrels which forces spirit into the wood then pulls it out again like wringing a sponge. Also the increased pressure will force out more of those highly volatile components through the wood leaving the richer tastier ones behind.

A good friend of mine makes some world winning whiskies. He will find barrels that aren't "behaving themselves" and put them in the sun to kick them along.
