Petaluma, Calif.—French winemaking supplier Oenofrance is seeking samples of wine with smoke taint so its research and development team can test the effectiveness of a new fining agent developed to remove smoke compounds. All samples will remain confidential and Oenofrance can retrieve samples from wineries in California. For samples outside of California, the company is also willing to pay for shipments direct to France. Oenofrance will only share results of the trials to wineries that submitted samples. To submit a sample for the free analysis, contact company’s U.S. office at (707) 321-6363 or oenofrance.com
