Attached are the Winter Grape Bud Hardiness results for Mid January.  The sampled hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on January 16th and 17th in the Okanagan Valley.

**Of a total of 540 buds sampled only 3 exotherm peaks were observed.  The values are given for the 2 locations where these were observed but the exotherms are likely from remnant tissues of already damaged buds.
