The charm of the first hops bath technique
Have you ever heard of the first hops bath? This technique, known in the beer world as FWH (First Wort Hopping), is a real delight for beer lovers. The idea is to add a good amount of hops just when the must move from the macerator to the kettle. In this way, the hops immerse themselves in the must, releasing all those aromatic oils that do the hard work to flavor the beer. It’s like a spa for hops!
The origins of magic
It is still discussed if the FWH was invented by pure chance. Apparently, an adventurous brewer decided to try something different and, in doing so, he discovered a new world of flavors. At the beginning of the twentieth century, this technique was quite popular, but then fell into disuse, almost like Mullet’s hairstyles. However, in 1995, the German magazine Brauwelt made a stir by highlighting the ‘rediscovery’ of this technique, especially in the Pilsner beers, which became more aromatic and complex thanks to the FWH.
Science and taste: an experiment that wins
A couple of German breweries joined to test this technique. Both prepared Pilsner beers while they stacked on the table two versions: one with the magic of the FWH and another without it. To the surprise of many, the beer with FWH showed a higher bitterness index (IBU), but with a much more balanced and pleasant taste!
The numbers do not lie
The results were fascinating. Brewery A, which used FWH, reached 39.6 Ibus, while B, which dispensed with the technique, stayed at 32.8. This even though the B used more hops in total. That is, the use of the technique not only increased bitterness, but also improved the experience of flavor.
How to make your own first hops bath
Ready to try the FWH at home? The brewers of all kinds, from fans to beer teachers, are hugging this technique. Ideal for beers that seek to make the most of their noble hops, although it is advisable for those looking for a fruit and fiddle profile of hops. The key? Add between 30-50% of the total hops to the kettle at the right time, just when the must begins to flow.
A small advice
It is advisable to use hops with low alpha acid content so that magic happens without a bitterness that burns. And although the increase in IBU may seem a great achievement, the complexity of flavor is where the FWH really shines.
Why a first hops bath?
The brewers, both veterans and rookies, feel fascinated by the power of the FWH, stating that it can change the taste profile of beer, especially in those relatively moderate Ale to hops. Although sometimes, it may be difficult to identify those new flavors. FWH’s chemistry is an enigma that is still deciphering, but some claim that it can contribute a slight adjustment to bitterness, about 10% of simple complexities.
So, the next time you raise a beer, remember the little secret of the first hops bath. Your tasteless papillae will thank you and perhaps, the hops too!
