History.

One word: History.  Groth Vineyards & Winery made Napa Valley history when their 1985 Reserve Cabernet Sauvignon received the first 100 point score (for a domestic wine) from wine critic Robert Parker Jr.  There is only ever one first time for anything, just one.  The first perfect score is a great history to have and Groth owns it.  In reading histories of the Napa Valley, it bothers me when I read articles about some or other bog-standard Napa Valley winery and the way in which said winery has helped shape the valley that both locals and visitors see today.  Groth is never mentioned.  (In the same way it irks me when a German, Charles Krug, is credited with producing the first commercial wine in Napa, when historical documents quite clearly show it was an Englishman, John Patchett.)  I always believe credit should be given where it is due.
Groth also have a history of making varietal wines that taste like what the label purports to be in the bottle: 38 years of that particular accomplishment to be exact.  (One would think that was a simple ask, but not every Napa Valley winery can claim that feat.)  Personally, my favourite Groth wine will always be any vintage of their Oakville Estate Cabernet Sauvignon  The Oakville is my go-to cab when I want to drink something that truly tastes like a cab.
Groth most recently proved that they are not the new-kids-on-the-winemaking-block when it comes to producing wonderful Cabernet sauvignon.  Groth's 2016 Reserve Cabernet Sauvignon was named no. 4 in Wine Spectator's top 100 wines of 2019 (an international list).
So what's the wine like?  Gorgeous.  The nose, redolent with blackcurrant, black cherry, lavender and mint is everything one would want in an Oakville AVA Cabernet sauvignon.  The mouth has more black fruit, red current, raspberry, elegant tannin structure and perfect acid (that is on point, like the acid in cranberries).  Those peeps at Groth know a thing or two about making a winning red wine...again, and again, and again.
Groth is history.

More often than not when meeting people for the first time, in a wine context, folks act a little surprised when I open my mouth and a still rather strong Liverpool accent spews forth (although most Americans wouldn't recognise it as such.) Their doubting looks often betray the fact that they are somewhat sceptical as to how on earth an Englishwoman could possibly know anything about wine. Why not, when everyone else you meet in the course of an average Napa Valley day is a self-proclaimed wine expert? I sometimes wonder, would my viticulture/oenology knowledge carry more weight if I delivered it with a French, Italian or, God forbid, German accent?

Considered by many (but not by me) to be the father of Napa Valley wine, Charles Krug is oftentimes credited with the notable distinction, in Napa wine-lore, of making the first commercial wine (and building the first commercial winery.) This is simply not true: the real star of the birth of the Napa Valley wine industry was, fee-fi-fo-fum...an Englishman!

Born in Lincolnshire in 1797, after much traveling around the United States John M. Patchett was 53 years old when he arrived in Napa in 1850. He proceeded to purchase a 100 acre parcel that became known as 'Patchett's Addition' and planted a vineyard of Mission grapes - the grape variety first brought to California by Franciscan monks. In 1857, Patchett harvested and crushed enough grapes to produce 6 barrels of wine which he then sold for $2 per gallon, thus becoming the first commercial winemaker ever in the Napa Valley. Then in 1859, he solidified his position into Napa wine-history by building the first commercial winery in the Valley, a 33' x 50' stone structure located in what is now downtown Napa. German immigrant Krug began his oenological journey in Napa by making wine at Patchett's winery, eventually founding his own in 1861.

Patchett, a brewer by trade, was by the mid 1860s considered to be the preeminent vintner in the entire Napa Valley. He continued to make wine until 1870, when at age 73 he sold his business and retired. John M. Patchett passed away in 1876 and is buried in Tulocay Cemetery. This is not just some fairytale, it is historical fact. It could only possibly have been made better if Mr. Patchett had hailed from Liverpool....all the best wine experts do, don't they?
