We first visited Rwanda in 2014 and over the last few years we've developed some very close relationships within the Rwandan coffee community. We first visited Bwishaza co-operative in 2015 and have been buying coffee from them every year.

Bwishaza co-operative is located north of Kibuye close to lake Kivu. You can view the exact location via the link to google maps. The co-operative traditionally focused on producing speciality washed coffees in lot sizes of 50 x 60kg bags. We still buy these larger lots as the cups scores are often very good and their best lots score around the 86 mark. In 2015 we asked the board members if they would be interested in producing some smaller experimental lots to include naturals and washed lots. 

The Bwishaza wet fermentation microlot is just 300kg in total and has been vacuum packed in 30kg boxes to ensure freshness. For this experiment we asked the producers to focus on hand sorting the cherry delivery to ensure as many defects were removed before using flotation to further remove any under-ripe cherry and contamination. This was then followed by pulping and a wet fermentation. Wet fermentation involves leaving the coffee to soak in water for 12-16 hrs to break down the mucilage left on the coffee after pulping (the other commonly used method is a dry ferment without water). After this the coffee is graded in grading channels and soaked a second time for 10-12 hrs. The results of this careful processed microlot are outstanding. We love the well balanced, clean and juicy fruit notes with excellent caramel like sweetness. 

In 2017 we funded a school repair project in the Rwanda Gishyita community. This year we are working on projects with a school local to Bwishaza and Liza washing stations. More information will be available soon and we are committed to working on long term projects in Rwanda.

    Good flavour

    I liked the round flavour of this coffee with only very slight acidity. A coffee to remember

    so versatile - great for espresso and filter

    Really smooth and sweet espresso
    and as a filter I love how mellow yet fruity it is. Really smooth again that you can drink loads of but not get bored of - give it a try! Though when they first send the coffees they have just been roasted so you need to wait a few days before using the beans to get the best flavour out of them

    Amazing quality

    I used to drink supermarket coffee and be satisfied, but after I tried Horsham Coffee Roaster's coffee, I changed my mind. When you grind these beans you get an aroma and taste that it's lacking in mass produced supermarket coffee. I've tried several small/artisan roasters, but this one is the best. It's just delicious. Orders are dispatched and delivered within a day or two, I highly recommend it!

    Excellent coffee - excellent value!

    You'd be hard pushed to find as good a coffee at this price anywhere else.. A high end product for sure! Will definitely buy again!

    Great coffee

    This freshly roasted Rwanda coffee is a delight to drink. From first opening the aroma spilled out, beans roasted to perfection giving a solid smooth tasting cup.
