Cornstar Lager — Mexican Style

The full Rainford's Brew Lab Lab Sheet for our Cornstar Lager — a proper Mexican-style session lager brewed from corn flakes, light malt extract, and Summit hops. Yes, really. And yes, it tastes like Heineken.

Inside your Lab Sheet:

✅ Full ingredient list with exact quantities and costs calculated from the Rainford Price List

✅ Step-by-step method — from grain boil to Pinter 3 cold crash

✅ The complete Rainford Scaling Table — scale from a 1L trial batch all the way up to a 25L big batch, with costs calculated at every volume

✅ Lab Notes — including Pete's post-video clarity correction so your lager clears properly first time (the video version didn't — this sheet fixes that)

✅ Head retention tips — the exact maltodextrin and flour combination that gives you that glass-coating lager head

✅ Target ABV, OG readings, fermentation temps, Pinter 3 settings and full conditioning timings

This is the sheet Pete wishes he'd had before he filmed it. Shed-tested, honestly reviewed, and budget-approved. Cheers! 🍺
