90pts, Vinous
The 2015 Flux, Mark Herold's entry-level red , is bold, juicy & inviting. Super-ripe red cherry, rose petal, mint & spice are all pushed forward in this racy, succulent wine. Dollops of Mourvedre & Syrah round out the blend. Drink it over the next handful of years.

90pts, Robert Parker Wine Advocate
Blended of 77% Grenache, 13% Mourvedre & 10% Syrah, the medium garnet colored 2015 Flux leaps from the glass with raspberry preserves, black cherry compote & redcurrant jelly with hints of baking spices, potpourri & bay leaves. Full-bodied & wonderfully plush in the mouth, it packs in the red berry preserves & spicy layers with a long, pepper-laced finish. Only 1,450 cases produced. –Lisa Perrotti-Brown

A big wine for a big personality. Like Dolly Parton hair, but in the form of a plush, expressive, juicy GSM blend, minus all the hairspray of course. Winemaker and owner, Mark Herold (who also holds a PhD!) is a man of exuberance. He lights up a room and knows how to share a laugh, and this infusion of personality comes bellowing out in the wines he produces in the best way possible.

Flux is fun. Flux is lively. Flux is an in-yo-face kind of friend that you love to have around and take shenaningan-filled adventures with. Because who doesn't need a little mischief? Gotta make the memories, ya know?

The fruit on this is just rich, palate coating loveliness. It's not shy at all. Ripe strawberry, blackberry, cherry compote heaven with hints of minerals, graphite, licorice and pepper. It smells big, it tastes big, it finishes big. It's a big 'ol hunk of GSM love! And only $15?! It's a no-brainer!


Juicy, plush, weighty Grenache blend with notes of ripe strawberry, crème de cassis, blackberry, black cherry and hints of brown sugar, graphite, licorice, crushed rocks, and almond skins.


For those that know him, Mark Herold is a larger than life, exuberant person who lives with gusto and possesses a depth of interest and lust for life that is contagious to those around him. His wines embody that same spirit!

Mark Herold’s first personal wine project, Merus, was a labor of love. For many years this wine was made in his home garage in downtown Napa and focused on premium Cabernet Sauvignon. Eventually his luxury brand was sold and because of a non-compete agreement, Mark was unable to make a Cabernet under his name for a period of time.

This did not deter Mark from embarking on a new adventure of producing non-Cabernet wines. His inspiration came from the great wines of France and Spain which influenced his palate and his personal wine collection over the years. Mark ventured to the pioneering grape growing regions of Lodi, Mendocino and Lake County even going so far as to bring budwood from Pingus in Ribera del Duero and planting that Tempranillo here in California for his Acha and Collide brands. Mark’s quest was to produce incredible blended wines that possess amazing character; wines that would please the everyday Cabernet drinker. This was the birth of Flux, Acha & Collide.
