We spilled the beans on our 'links' page...
when we said that we're happy to share what we've learned. Climate information is no different. We live on the edge of what is considered to be a viable grape growing climate. Weather is perhaps the single biggest hurdle that we face on an annual basis.

So for all of you with grape stained fingers, we offer you some weather data that you might find helpful. Admittedly, you've got to be a grower to 'get off' on this stuff, so fill yer boots!
