Fresh wort kits have revolutionized homebrewing for thousands of beer enthusiasts. They make it possible to brew real craft beer in a simple and time-saving way – without mashing and boiling. But not all fresh wort kits are created equal. Today, there are two main types on the market: 15-liter kits that need to be topped up with water, and Brewshop's 20-liter kits which are 100% finished wort, ready for fermentation. The difference is greater than many believe – and largely concerns quality.
15L fresh wort kits: simple, but a compromise
15-liter fresh wort kits come with 15 liters of pre-brewed wort, which needs to be topped up with 5 liters of water at home to reach the correct volume of 20 liters. This may seem practical, but there are several disadvantages:
-
Dependent on home water quality – which varies greatly and affects taste, aroma, and fermentation conditions.
-
No water adjustment – you risk poorer mouthfeel and unbalanced flavor profiles.
-
Increased risk of contamination when water is added afterwards.
-
Made for lower shipping costs and higher margins (?), not to deliver maximum quality.
-
For beginners, it can be tempting to choose this type of kit, but the result is rarely on par with what professional brewers expect – precisely because the water, which makes up to 95% of the beer, is not controlled.
Water chemistry – the very foundation of good beer
Water is not just a base for beer – it is an active ingredient that affects taste, mouthfeel, fermentation process, and aroma. Different beer styles require different mineral balances in the water, and professional breweries use water adjustment with salts such as calcium sulfate (gypsum), calcium chloride, sodium bicarbonate, etc. to adapt the water to the beer style. A classic pilsner beer, for example, needs soft water with low mineral content, while an IPA requires more sulfate to enhance the hop profile.
Poorly adjusted or impure water can give a metallic taste, make the beer flat, or cause stress to the yeast. Therefore, it is crucial that the wort you use is based on the correct water profile. In Brewshop's 20L fresh wort kits, this has already been done by professional brewers – you get optimal water chemistry that gives the beer the right balance, clean taste, and higher stability in both fermentation and the final result. This is a great advantage compared to kits where you have to add your own water – which is often not ideally adjusted for beer production.
20L fresh wort kits: pre-water-adjusted and brewed by professionals
Brewshop's 20L fresh wort kits are something else entirely. Here you get 20 liters of 100% finished wort – precisely water-adjusted and professionally brewed by some of Norway's best microbreweries, such as Austmann and Amundsen Bryggeri.
-
No water needs to be added – you get exactly the wort the brewery made, ready for fermentation.
-
Perfect water adjustment with the right salts for taste, aroma, mouthfeel, and fermentation conditions.
-
Safety and purity – no risk of contamination from water added at home.
You get yeast and any additives like dry hops – and all you need is a fermenter. These kits are made for those who value simplicity without compromising on quality.
As long as you control the temperature during fermentation and maintain cleanliness, you get a starting point to make a beer as good as the very best breweries – while also ensuring a fresh product, which you don't always get in stores or at the liquor store. This is especially true for aromatic beers with a lot of hops, which are perishable even if a long shelf life suggests otherwise.
Brewshop's 20L kits – in a class of their own
Whether you are new to the game or an experienced homebrewer, you will notice the difference. Brewshop's 20L fresh wort kits from Austmann and Amundsen give you professionally brewed, fresh, and water-adjusted wort – ready to use, without shortcuts. You don't have to worry about water quality, oxygen, or incorrect mixing ratios.
