It’s unusual to have 1000 c.h. in the Bay Area, I usually have 700-800 outside of Tracy. What’s your location? For high brix, summer temperatures and sun are more important. It’s easier to get higher brix fruit in hotter inland areas compared to foggy coastal areas. Also, control over irrigation is a key factor, you don’t want to overwater your fruit trees, but they need to get enough water to do well.
Figs are very sweet, especially the main crop, provided that you have enough summer heat. Most fig varieties love heat. Fig trees are also very easy to grow, they are basically weeds.
Another important thing to take into account is ripening time. You don’t want all your fruits to ripen over a short period of time — then you will have too much fruit for a few weeks and nothing for the rest of the summer. Plan carefully to have your fruit varieties ripening in a succession.
White Nectarine — Arctic series (note that Arctic Glo has more acid then the rest), Summer Silk, Spice Zee, Crimson Belle. Generally, if you have right growing conditions most white nectarines will have very high brix.
Yellow Nectarine — Honey series is subacid (Honey Kist is available to backyard growers), but many others will have high brix along with some acid kick.
White Peach — Donut (Stark Saturn), Strawberry Free, Snow Beauty, Nectar, Fei Cheng Tao, Paradise, Athena, Snow Giant and many others.
Yellow Peach — June Pride, Sweet Dream (low acid), Kaweah, Kit Donnell, Rio Oso Gem, Sweet September (low acid).
Pluots — Emerald Drop, Flavor Queen, Flavor Grenade are the sweetest, but Flavor Supreme and Flavor King have more interesting flavor.
Apricots — Orangered (top early season apricot for both brix and flavor), Golden Sweet, Tilton. Some other varieties may have lower brix but more interesting flavor, in my opinion. Get at least one white apricot variety, e.g., Lasgerdi Mashhad.
