Dark Rock | The Bosses Boss Double IPA | Part Grain Beer Kit
The Bosses Boss Double Hopped Double IPA is a beer with attitude. Also known as an Imperial IPA, this full-on American-style beer is the superpower of pale ales. Big citrus flavours punch through from the freshest vacuum-packed Centennial, Amarillo and Simcoe hops. This intense flavour is balanced with a malty richness which is provided from commercial grade premium malt extract coupled with the freshest grains.
You will also need to add Brewing Sugar (not supplied) to make to 6.5% ABV.

Why Choose Dark Rock Part Grain Beer Kits?
Dark Rock Part Grain Beer Kits strike the perfect balance between ease and authenticity, making them the ideal choice for anyone who wants to brew exceptional beer at home without jumping straight into All Grain Brewing. Whether you’re just starting out or already an experienced brewer, these kits help you produce commercial-quality, flavour-packed beer with confidence.
Unlike basic extract kits, these take your brewing to the next level by combining traditional extract methods with a simple steeping and boiling process. Using carefully selected malt grains and hops, you’ll unlock richer, more complex flavours and aromas—giving you far greater creative control over your brew. All you need is standard home brewing equipment, plus a 12-litre pan and a thermometer (see full equipment list below), making it an easy upgrade from standard extract kits.
Each kit comes with 3kg of premium malt extract, a freshly packed blend of grains, and top-quality hops sourced from the best producers worldwide. We weigh and pack every ingredient fresh to order, while hops are vacuum sealed in nitrogen-flushed bags to lock in their full character and freshness.
To make your brewing journey even smoother, we provide expert guidance and a wide variety of beer styles to explore—from hazy pale ales and rich stouts to crisp pilsners. With Dark Rock Part Grain Kits, you get everything you need to create truly exceptional beer at home.
Brew with confidence. Brew with Dark Rock.

Brewers Tips
This kit includes Pure Brew, a professional enhancer that boosts fermentation and treats brewing water. It feeds yeast with vital nutrients, while removing Chlorine and Chloramine, which can cause off-flavours. Since water quality is key to great beer, we strongly recommend using Pure Brew in every brew for consistently better results.
You’ll also get Harris Starbrite finings, a vegan-friendly clarifier that helps your beer clear quickly and encourages sediment to settle. This is especially useful if you’re kegging, as it reduces the risk of haze and sediment transfer.
To make brewing even easier, we’ve included a muslin grain bag and hop t-bag. For a more advanced setup, consider adding a metal hop spider. It offers better hop circulation during the boil, is easy to clean, and can be reused again and again.

First part grain and I’m really pleased with the results.
A noticeable difference in mouthfeel which I’m guessing comes from the steeped grains. A powerful punch of fruity hops is what you get from this kit, it is by far the best kit I have brewed to date.
An absolute belter. So easy like the other part grain kits. The two huge bags of hops were amazing. Will be buying again after I do the NEIPA kit
