I loved the 2018 M Proprietary Red Wine, another gorgeous wine from this tiny estate. Lots of crème de cassis, blueberries, iron, and a kiss of crushed stone-like minerality give way to a deep, full-bodied, concentrated wine with plenty of baby fat mostly concealing sound underlying structure. A blend of equal parts Cabernet Sauvignon and Cabernet Franc, it's going to take 7-8 years to shed some fruit but should be long lived.
