Base Malts
Base malts make up the bulk — typically 80–100% — of an IPA's grain bill. They are lightly kilned malts with enough enzymatic power to convert not only their own starch but any added adjuncts during Mashing. They are the foundation everything else is built on.
#The Major Base Malts
| Malt | Origin | Character | Typical use |
|---|---|---|---|
| American 2-row pale | USA | Clean, lightly sweet, neutral | Default base for West Coast IPA |
| Maris Otter | England | Rich, biscuity, "bready" | English IPA, characterful pales |
| Pilsner malt | Germany/Belgium | Very pale, soft, faintly honeyed | Cold IPA, Belgian IPA, Brut IPA |
| Pale ale malt | UK/EU | Slightly toastier than 2-row | Balanced American & English IPAs |
| Vienna / light Munich | Germany | Gentle toast, golden depth | Adds malt complexity without darkening much |
#2-Row vs. 6-Row
"2-row" and "6-row" describe how barley kernels are arranged on the head. American 2-row pale malt — plumper kernels, lower protein, cleaner flavor — is the standard IPA base. 6-row has higher enzyme content and protein but a grainier taste; it is mostly used in adjunct-heavy industrial lagers, not craft IPA.
#Choosing a Base Malt
A West Coast IPA on American 2-row tastes clean and lets hops dominate. The same recipe on Maris Otter gains a biscuity, slightly nutty richness — subtle, but the difference between a hop showcase and a maltier, English-leaning beer.
The choice is stylistic. Pale 2-row for a neutral hop platform; Maris Otter for old-world depth; Pilsner malt for the crisp, lean base of a Cold IPA or Brut IPA.
Very pale Pilsner malt carries more SMM, a precursor to the vegetal off-flavor DMS. Beers built on it need a vigorous, uncovered boil to drive it off — see Off-Flavors in IPA.
#Base Malt and Body
Base malt provides fermentable sugar, but mash temperature decides how much survives as body. Most IPAs also cut a portion of base malt with simple sugar (dextrose) to thin the body and boost ABV without adding flavor — a key trick for the dangerously drinkable Double IPA.
