Why IPA Foam Ain’t What It Used to Be
After spending two years nestled in the warm tortilla-fold of Michoacan, Mexico, I returned to California expecting certain things: traffic, overpriced avocados, and IPAs with foam — you know, the normal stuff. But no. The craft beer I once knew had changed — like an old friend who used to be the life of the party but now sighs a lot and wears Hokas.
What struck me most — and yes, it felt personal — was the absence of head. Not mine, though arguably that’s long gone, but the kind that used to crown a pint glass with snowy, cloud-like dignity. These days, every IPA I’m handed at the bar or I pour from a can has the low carbonation of a forgotten bottle of sparkling water that’s been sitting in the back of the fridge since last Christmas, and the lack of foam that makes me question everything I thought I knew about what a good IPA should be. There it sits in front of me, hoppy as hell, yes — but also just liquid disappointment and the faint echo of better times.
Modern West coast IPA's have a way of showing up at your table looking like they’ve already been sipped. One big culprit is dry hopping. Great for aroma — really, it’s why your beer smells like a bag of grapefruit peels and why you love it, but when brewers load it in late, they also add oils and compounds that kill foam. It still smells amazing, but the head takes the hit.
A lot of these West coast beers also use low-protein malts, or even adjuncts like rice or corn to keep things light and crisp. That works for keeping the malt flavor low to highlight the hops, sure, but it means there’s less structure to hold any foam in place. And then you’ve got all the filtering and fining — the stuff that makes the beer clear and pretty, but strips out the proteins that help with head retention. Crystal clear often means no drama in the glass. That said, there are many that are unfiltered or purposely hazy that still present headless and low in carbonation.
Some yeast strains don’t help either. They’re chosen for a clean finish, or bio-transformation but don’t bring much to the table when it comes to foam. So the beer drinks smooth and fruity, but looks like someone forgot to finish pouring it.
I want to take the lessons I've learned from my sad experience with many of the current Ipa's I've drunk here and utilize them in my home brewery in Mexico when I return. I still want some of those hop bombs but may make some ajustments to my grain bill to mitigate this negative hop oil effect. I think most effective would be an increase in dextrin malt. My thought is that the added body may help. But I'm also willing to try tossing in some wheat or chit malt to help build that foam. I may ease up on the dry hops, I still want that aroma, but maybe I won’t go overboard. A lighter touch can mean better head retention and still get the point across that it's a hoppy beer. Finally, I'll try to dial in my carbonation levels to 2.5 volumes. I suspect that some of the canned beers I've had are low in carbonation out of fear of over-carbonation from a refermentation in the can due to hop creep. That's just me guessing.
In the mean time there are some West Coast breweries I would recommend that still build an Ipa with proper foam:
- Beachwood Brewing (Long Beach): West Coast bangers with killer head retention.
- Russian River Brewing (Santa Rosa): “Pliny the Elder” still crushes it with stable foam and big hops.
- Sierra Nevada Brewing Co. (Chico): Classic brewery, textbook foam quality.
