Diamond Creek History, Overview
Albert Jack Brounstein created Diamond Creek in 1968 with his purchase of 79 acres in the Diamond Creek canyon. It’s a good thing the land was bought by Al Brounstein because the owner at the time was considering turning the site into a golf course! Al Brounstein became interested in wine after taking a wine class at UCLA. He started out working as sales rep for Sebastiani vineyards. He furthered his studies by working weekends at Ridge vineyards. At the time, his concept was way ahead of its time. Al Brounstein’s desire to create multiple single vineyard wines from Diamond Creek was unique in its day.
The stated goal of Diamond Creek was to display the differences in the terroirs and micro climates found in each unique, vineyard site; Volcanic Hill, Gravelly Meadow, Red Rock Terrace and Lake Vineyards. Diamond Creek gets another award for being the first California winery to produce wine made from only 100% Cabernet Sauvignon. After purchasing the land for the then very expensive price of $1,400 per acre, Al Brounstein began replanted some of the acreage with vines that came from two of the First Growths in Bordeaux. The vines were smuggled in through Mexico! Sadly, the colorful, Al Bournstein died in 2006 at 86 years of age. He was survived by his second wine, Boots Brounstein, their son, Boots Bournstein; son Gary Brounstein and two stepsons Phil Ross and Chuck Ross, five grandchildren and one great-grandchild. Phil Ross and Boots Bournstein are in charge of managing Diamond creek today.
Diamond Creek Vineyards, Wines, Winemaking
The vineyards of Diamond Creek are situated on different soils, but they share some commonalities. Located in the narrow Diamond Creek canyon, the parcels are all close to the same 600 foot elevation and they were planted from budwood obtained from some of the First Growth wines of Bordeaux. Or so the legend goes. The first Diamond Creek wines came from the poor 1972 vintage. But even in that difficult, first vintage, Al Brounstein was able to see the differences in each of the wines due to their distinctive soil types.
Diamond Creek Volcanic Hill is an 8 acre vineyard planted with Cabernet Sauvignon and a small amount of Petit Verdot on a terroir consisting of volcanic ash that was deposited from Mt. Konocti on a south facing slope. Due to the vast differences in the elevations and slope, Diamond Creek Volcanic Hill can take as long as 3 to 4 weeks for the harvest to finish. The Volcanic Hill vineyard has a slightly warmer micro climate and because of that extra heat, Volcanic Hill is always the first of the Diamond Creek vineyards to be harvest. The wine is aged using 100% new, French oak barrels.
Diamond Creek Red Rock Terrace is a 7 acre, vineyard planted with Cabernet Sauvignon on red tinted clay soil with a large amount of iron deposits on a steep grade with a northern exposure. And yes, as you would expect, the vineyard is planted using a series of terraces as the hillside plantings are quite steep. When you look at the vineyards, you clearly see the red soils which gave the vineyard its name. Red Rock Terrace is almost always the second of their vineyards to be picked. The wine is aged in 100% new, French oak barrels.
Diamond Creek Gravelly Meadow is a 5 acre parcel planted to Cabernet Sauvignon on a pre-historic river bed, with rocky, gravel based soils. This parcel does not have the same level of elevation as the other parcels. The first vintage for Gravelly Meadow was the 1974 vintage. This came out 2 years after wines from the other vineyards were produced. The Gravelly Meadow vineyard is dry farmed. Aside from Lake vineyards, this is the lowest yielding vineyard in their portfolio. The wine is aged using 100% new, French oak barrels.
Diamond Creek Lake Vineyards is the estates smallest site. It takes up only ¾ acre. It is also the coolest of all the Diamond Creek micro climates. The site is also wettest as it’s situated as you would imagine next to a lake. Lake Vineyard is not made every year. The wine is only produced when the specific quality of the vintage warrants it. In fact, since Diamond Creek Lake was first produced in 1978, it has only been made 14 times over the past 40 years. When the wine is not made, the grapes are blended in with Gravelly Meadow. Diamond Creek Lake Vineyard has the coolest terroir out of all their sites and is the last to be harvested. Lake vineyards is one of two vineyards that is completely dry farmed. On those rare occasions when the wine is made, it’s aged using 100% new, French oak barrels.
From time to time, a blend of all three vineyards has been bottled. Other special bottling’s include Special Selections and First and Second Pickings. In at least 4 vintages, 1989, 1991, 1992 and 1993, Diamond Creek made a Gravelly Meadow Lake Blend. A few vintages have been produced from each of three main terroirs, Gravelly Hill, Red Rock Terrace and Volcanic Hill that are named Micro Climate on the label. Special labels were produced for Diamond Creek wines for each of the vineyards to celebrate their 30th anniversary.
The wines of Diamond Creek are vinified in stainless steel tanks. The wines are now aged in 100% new, French oak barrels for up to 22 months, depending on the character of the vintage and the vineyard. The average production for all 21 acres is on average close to 3,000 cases per vintage. In 2006, Al Bourstein passed away. His family continues to manage the Diamond Creek estate today.
Serving and Decanting Diamond Creek with Wine, Food, Pairing Tips
Diamond Creek wines are best served at 15.5 degrees Celsius, 60 degrees Fahrenheit. The cool, almost cellar temperature gives the wine more freshness and lift. Young vintages of their red wine can be decanted for 1-3 hours, depending on the character of the vintage. This allows the wine to soften and open its perfume. Older vintages might need very little decanting, just enough to remove the sediment.
The wine of Diamond Creek is best served with all types of classic meat dishes, veal, pork, beef, lamb, duck, game, roast chicken, ribs, hamburgers, barbecue, roasted, braised, grilled dishes and stews. Diamond Creek is also good with Asian dishes, hearty fish courses like tuna, salmon, mushrooms and pasta.
I’ve been fortunate to have tasted most of the pre 1990 Diamond Creek wines several times. For my palate, these wines are compelling. In blind tasting’s, the 78 Diamond Creek Volcanic Hill can stand up to many of the best First Growth wines from Bordeaux. At 33 years of age, they are still young, fresh, vibrant and exacting. Sadly, after 1984, things changed and they were no longer making at the same level of quality. After a slow period of almost 25 years, recent vintages have shown a lot more promise. Hopefully, fortunes will continue to change and they will keep increasing the levels of quality found in their unique style of California wine. The 2009 vintage seems to have sparked the revival of fortunes at Diamond Creek Vineyards and the 2012 tasted recently was a knock out! All three vineyard designated wines were stunning.

|2013||Diamond Creek Cabernet Sauvignon Volcanic Hill (Diamond Mountain)|
Powerful deep, rich and concentrated, with a regal, quality to its ample tannins. There is a lot of depth that is easily seen with its multiple layers of fruit. The sweet, ripe, dark berries and the perfect hint of earthy chocolate in the finish sticks with you for close to 50 seconds. This is serious juice, made in a great style that is impossible to stop drinking. That being said, like all great wines, Diamond Creek is a wine to lay down for at least a decade or longer. I'm still drinking my 1978's!

|2013||Diamond Creek Cabernet Sauvignon Red Rock Terrace (Diamond Mountain)|
Rocks, burning embers, cassis, wet earth and blackberry aromas stand out. Powerful, balanced, rich, plush and mouth filling, there is weight and substance in abundance with freshness and pure sweet fruits. You can drink it young, but I’d age it for at least a decade.

|2013||Diamond Creek Cabernet Sauvignon Gravelly Meadow (Diamond Mountain)|
Truffle, herbs, and dark fruits open up the wine with coaxing. The wine is tight and holding back, so some effort is needed to wake it. Deep, long, full bodied, and with loads of dark chocolate covered fruits on the palate paired with freshness in the finish. Stylistically, the wine is slightly austere, but with great character, depth and mouth feel. You’ll need to be patient with this one. But it is going to be worth the wait. And I imagine the score will move up as the wine softens and opens, but we'll have to wait and see.

|2012||Diamond Creek Cabernet Sauvignon 40th Anniversary Volcanic Hill (Diamond Mountain)|
Deep, dark ruby in color. Smoke, licorice, caramel, earth, tobacco and ripe blackberry notes are in abundance. The wine is deep, fresh, long, concentrated and really displays a purity of fruit. This is really a great expression of mountain fruit that leaves you wanting another sip, before your glass is emptied. But this is an ager that needs time to soften and come together for maximum pleasure. I might not see this in 30-40 years, but I would not be surprised if the wine was rockin’ at that point in time.

Dark ruby in color, with an earthy, smoke filled cassis and licorice nose. Full bodied, concentrated, fresh and lively with a polished, mineral driven, cassis packed finish. The finish really lingers. The wine needs a decade in the cellar to become civilized.

|2012||Diamond Creek Cabernet Sauvignon 40th Anniversary Gravelly Meadow (Diamond Mountain)|
Smoke, licorice, fresh herbs, cassis and tar aromatics make up the perfume. The wine is more refined than Gravelly Meadow in the same vintage. There is a richness to the texture coupled with fresh blackberry and cassis, in the full bodied finish that stands out.

This is a super wine in such a great style. In a semi sleeping mode for the moment, decanting and air brought out all the fresh blackberries, tobacco, smoke, earth burnt wood from a fire pit aromas anyone needs. Rich, dense, tannic, concentrated and fresh, 10 more years of sleep in the cellar will add a lot to this beauty.

OK, this is still so young, but there is a lot to like about the layer after of ripe, sweet, fresh, juicy fruit, licorice and campfire ember nose. And the wine is even better when it hits your palate with all those ripe blackberries, blue fruit, licorice and ripe tannins. Give this time and it will be even better.

|2008||Diamond Creek Cabernet Sauvignon Volcanic Hill (Diamond Mountain)|
Crème de cassis, licorice, smoke, cedar, earth and lead pencil aromas create the Bordeaux styled perfume. Powerful, concentrated, bright and fresh, this structured wine has mouth searing tannins. This could take 20 years to come around. But as the 1978 Diamond Creek Volcanic Hill is still going strong at close to 35 years of age, if you’re really young and very patient, it might be worth the long wait.

With forest floor, tobacco, cedar, cassis and blackberry aromas, this tannic, structured, old school California wine will need a lot of time to soften. The wine is austere and masculine in style, with cassis and cranberry in the tannic finish. Fans of Cabernet Sauvignon from the 70’s will feel right at home with this wine.

Tobacco leaf, truffle and cassis scents are easy to find in this full bodied, traditionally styled, bright, California Cabernet Sauvignon. The wine ends with crunchy, cassis and blackberry with a hint of green in the tannic finish. This is not a fun wine to drink young.

Tart, bright, crisp and earthy, with a strong, herbal, cedar and leafy component. Medium-full bodied, the wine is better on the nose than the palate. Lovers of this style of less ripe, old school, classic Cabernet Sauvignon will like this more than I did.

A nice wine here, with lots of secondary tobacco, cigar, cassis and earthy notes in the boquet. Tannic, young and firm, this could show better with more age. Only time will tell.

This is starting to show secondary characteristics of cassis, tobacco, minerality, cedar wood, smoke, blackberry and lead pencil aromas. Full bodied and structured to age, while not at the level of Diamond Creek produced in the 1970's or early 1980's, this is a good example of a classic styled, California Sauvignon.

Firm, classic, cassis filled with a green slant to the herbs, cedar and tobacco leaf nuances. Not quite stoic, but there was an austerity felt here on the mid-palate and finish. I liked the wine, but it was on the rustic side.

Nice enough, but not at the level of quality that should be demanded for a wine at this price point. More interesting on the cassis, blackberry, leafy, forest and tobacco nose, than on the tannic, structured, full bodied, concentrated, but austere palate. The wine is still youthful, so there is no hurry to drink it, but I doubt it is going to improve or change its spots from here.

It is hard to believe this is so young, and its over 30 years of age. But the truth is in the bottle. Full bodied, concentrated, powerful, and tannic, with loads of fruit, but a wall of tannin that is not yet resolved. Think of 1986 Bordeaux and you get the picture. Not my bottle, but I am happy to have a few stashed away in my cellar.

Better than expected, the wine is still young, slightly coarse in texture, but filled with cassis, tobacco, blackberries and a touch of acidity and cranberry in the finish. All things considered, for a 33 year old wine from an off vintage, this is quite a success. If you're seeking a birth year wine from this difficult vintage, this is a not a bad way to go. In fact, that's exactly what this bottle was opened for.

This bottle was spellbinding! It tasted like it was 15-20 years old, not 40. Still concentrated, deep, fresh, vibrant and dark, the is a depth of flavor here, coupled with palate coating intensity, that makes it impossible not to take another sip. The dark berries are fresh, with energy, length and complexity. The wine has become shockingly expensive over the past few years, but it is a remarkable tasting experience for those interested in the best classic California Cabernet Sauvignon wines. This is as good as it gets!!!

Stunning in every sense of the word, this tasted like it was at least 20 years younger than its true age. The nose reminded me of a First Growth Pauillac, with its tobacco, herbs, earth, cassis, blackberry and cedar wood profile. Fresh, lively, ripe fruits fill your palate with the right amount of acidity and fruit to make you go back for sip after sip.

1978 Diamond Creek Volcanic Hill announced its presence with cedar wood, cassis, tobacco, truffle, earth, smoke and forest floor aromatics. Full bodied with layers of cassis, spice and blackberry, this mineral driven expression of Cabernet Sauvignon would more than hold its own in a blind tasting against the First Growths. I've been able to taste the wine a lot over the years and as good as this bottle was, I've had even better bottles! If you want to experience one of the better examples of mature California wine, this is about as good as it gets.

Tobacco, cigar box, creme de cassis, truffle, smoke, forest floor and dark plums always make me think of Pauillac. Served blind, that was my guess. Wrong. This vintage Caliifornia Cabernet Sauvignon would fool most people. Full bodied and concentrated, this powerful, fully mature wine ends with cassis, cranberry and spice. I have tasted better bottles. At almost 34 years of age, perhaps it's a sign that the wine needs drinking.

Stunning aromas of Cuban cigar, truffle, stone, cassis, blackberry and forest floor paired perfectly with the layers of pure cassis and black fruits.

1978 Diamond Creek Lake grabbed your attention as soon as your nose met the glass. The complex aromas of scorched earth, smoke, tobacco, cassis, blackberry, caramel, black cherry and charcoal let you know this was a stunning wine. In the mouth, its concentrated, full bodied, rich, deep and packed with flavor. The long, pure finish was filled with endless layers of cassis, earth and spice. This is probably the best bottle of mature California Cabernet Sauvignon I’ve had the privilege of tasting. Needless to say, I was blown away when the bottle was revealed. 1978 marked the debut vintage for Diamond Creek Lake vineyard bottling. Very little of this wine was made and only a handful of bottles remain. It was a wine I thought I’d never see.
