    Introduction to hop chemistry

    I've just come across this open-access paper from Weihenstephan, which is a nice introduction to the "classic" chemicals in hops. It's ten years old so thiols like 4MMP get only a passing mention, but it's a great place to start for those who don't know their sesquiterpenes from their prenyl...

    Fermenting hops for new flavours

    This is a fun paper from Hohenheim : https://www.sciencedirect.com/science/article/pii/S1466856424002546 Fermenting 10g/l infusions of Callista hops - even manky ones with lots of brown on them - with mycelium of the "mushroom" Coprinellus micaceus, the mica cap or glistening inky cap, forms...

    From the lab - evolution of hop/cannabis sex chromosomes

    This is of no relevance except to the hardened hop geeks, but this is a nice preprint where they've sequenced genomes of various Cannabis and Humulus (sub)species, paying particular attention to the sex chromosomes. They also talk a bit about sex-linked "flavour" genes like the...

    Lachancea and other bugs for winemaking

    This is an interesting paper looking at combinations of Lachancea (ie the acid-producing yeast that brewers know as Lallemand Philly Sour) or lactic bacteria in combination with different yeasts as a way to compensate for low acidity from the must. Their favourites are Lachancea followed...

    Fermentis BR-8 - first dried Brett

    Fermentis are very proud of their new baby, BR-8, so much so they even did a fancy Guinness-style video which tells you absolutely nothing about the product but tells you how to feel about the "brewer’s journey, through his thoughts and doubts. It’s about his path towards his most creative self...

    How long can you leave liquid yeast after the best-before date?

    It seems to be a regular question, how long before liquid yeast is dead or unusable. Well here's proof that you can revive liquid yeast that's nearly 5 years old, this was an out-of-date pack of WLP540 that I got from the old Hop & Grape ages ago, then with one thing and another I didn't get...

    Learning to write recipes with a SMASH

    There was a thread on another forum asking for a recipe for a SMASH (single-malt-and-single-hop) beer, and my reply turned into a more general introduction to how to construct a recipe, thinking about how much grain you need for a certain alcohol content and that kind of thing. It assumes you...

    The European Beer Consumers Union (EBCU) has published a style guide, led by Tim Webb, whose career has included organising CAMRA's Great British Beer Festival in the early days and writing books such as CAMRA's Good Beer Guide Belgium. It's more descriptive and less prescriptive than the BJCP...

    Disentangling photoperiod from hop vernalization and dormancy for global production and speed breeding Bauerle, W.L. Sci Rep 9, 16003 (2019) doi:10.1038/s41598-019-52548-0 "Photoperiod is known to interact with temperature to control flowering in hops. Studies have stipulated that resting...

    HBT hop photo database

    Since we're coming (in the Northern hemisphere at least) to the culmination of the hop-growing year, I was thinking it was time to get our cameras out to help those HBTers who have hops they can't identify. Particularly if you have access to traditional landraces which are the ones that people...

    Mystic, Godiva hops, Saccharolicious yeasts in Sweden

    I happened to come across humle.se recently and was surprised to see them selling the very latest Farams hops, including Mystic which is the first time I've seen them in the homebrew world, not even in the UK. Also Godiva (which Malt Miller have had since last year, and which seems quite...

    St Austell recipe for Daylight Robbery (which became Tribute) - from the horse's mouth

    Roger Ryman has dug up the recipe for Daylight Robbery, the beer that he brewed on the 2.5brl kit at St Austell for the 1999 solar eclipse, that evolved into Tribute with the addition of some Styrians. 2.5brl is 108 US gallons or 409 litres, so multiply by 0.046 to get to 5 US gallons. Hmm -...

    WLP073 Artisanal Country Ale - Bière de Garde strain

    WLP073 is a current seasonal release from White Labs having been put in the Vault in 2017. I thought I'd start a thread to encourage a centralised discussion as there seems to be nothing about it on the web. Sounds nice : "It produces slight esters and mild phenols, while preserving the sweet...

    Redhook Longhammer harvest?

    Hey folks I came across a bottle of Redhook Longhammer recently, a rare sight on this side of the pond and bought it on a whim. I assume it’s not bottle conditioned, but I did come across a thread from 2010 where someone had recovered yeast from an unknown Redhook bottle. Has anyone got more...
