IPA Session Beer Recipe (All-Grain & Partial Mash)

Two men drinking a ipa session beer.“Session” beers are all the rage these days. Though super high-gravity beers have their place, beer drinkers seem to be trending back to beers that are easily drinkable – something you can enjoy a few pints of without necessarily getting a headache the next day. Such is the case with this IPA session beer recipe.
Homebrewing geeks may be familiar with the beer writer Ron Pattinson and his blog, Shut Up About Barclay Perkins. Ron dives deep into brewing history, going to great lengths to dig up old beer recipes and statistics on how beer was actually made many decades ago. Believe it or not, historical beer recipes didn’t always fit very snuggly into the BJCP Style Guidelines.
This was certainly the case when looking at beer recipes from during WWI and WWII. Such was a time when barley was rationed and brewing ingredients came at a premium. This certainly affected the brewing industry in the UK, where English barley malt was supplemented with imported malts and adjuncts like corn and sugar.
Today’s IPA session beer recipe is modeled after a beer from the Whitbread Brewery of London (Incidentally, Whitbread yeast is derived from that brewery. Safale S-04 is the dry yeast version). The beer has a much lower gravity than what we would normally consider for an IPA, with an ABV of just 4.7%. Still, it’s a bitter beer at 75 IBUs. The use of about 20% simple sugar should make this beer pretty dry on the finish.
Curious what kind of beer people were drinking nearly 100 years ago? Give this recipe a try!
