California Ale V
The chalky, high-flocculating cousin of the standard American strain. Leaves slightly more body and drops so hard the beer is bright without filtering.

Labs do not confirm each other’s provenance and these are not guaranteed identical. They are close enough to plan a batch around, which is what the list is for.

Pitching it
One fresh sachet or a healthy starter is enough for an ordinary-gravity ale. Above about 1.060, build a starter or pitch two: under-pitching produces fusel alcohol that no amount of conditioning removes.

Other ale strains
American Ale
73-80%Clean and neutral, the workhorse for anything where the hops or malt should do the talking. Ferments reliably and drops reasonably clear.
English Ale
68-75%Malty and lightly fruity, finishing higher than an American strain and leaving body behind. Flocculates hard, so it needs rousing if it stalls.
London Ale III
70-75%The hazy IPA strain: enormous stone-fruit esters, low flocculation, and a slick body that suits a beer built on oats. Stalls if it gets cold, and sulks if you rouse it late.
Nottingham
77-82%Clean, fast, dry and almost unreasonably tolerant of low temperatures: it will ferment respectably at 13C, which makes it the cheapest way to fake a lager.
Yorkshire Ale
67-72%The Timothy Taylor strain: a soft, stone-fruit character and a very low attenuation that leaves a bitter tasting full at 4%. Needs rousing or it stops early.
Irish Ale
71-75%Slightly tart and dry with a light diacetyl that suits roast malt. The strain that makes an Irish stout taste Irish rather than English.
