Pitching it
Rehydrate properly rather than sprinkling dry yeast on cold must, and plan the nutrient before you pitch: staged additions over the first third of the fermentation, not one dose at the start.

Other red strains
RC 212
14%The Burgundy strain: emphasises red fruit and preserves the delicate colour of thin-skinned varieties. Hungry, and it will make hydrogen sulphide if you do not feed it.
D254
16%Big, ripe and mouth-filling, emphasising jammy fruit and softening tannin. The strain for a warm-climate red you want to drink young.
D80
16%Builds structure and length rather than fruit, and holds colour well through a long maceration. A strain for wines meant to age.
Cabernet CS2
16%Selected from Bordeaux for Cabernet: emphasises blackcurrant and cedar, and integrates hard tannin better than most.
Syrah Rhone 2226
16%A Rhone isolate that emphasises pepper, dark fruit and a soft finish, and copes with a hot ferment better than most.
