product description for SISU provides some interesting background on the product. It says “SISU Extreme has a refreshing and intense flavor of spearmint and menthol! The evenly filled portions are soft to the touch and have a great feel under the lip. They are dry which give a low drip but a long lasting release of flavor and strength. Strengthwise it lands on 20 mg/g which gives a powerful release of nicotine, and classifies it as ultra strong. SISU is an expression from Finland that stands for determination and bravery, it's about sticking with it even when the going gets tough - SISU is good character and now also a good snus!” The can weighs in at 11 grams, containing 17 portions at 0.65 grams per portion. The nicotine content is 2.0%, or 20mg/g, which breaks down to 12.94mg/portion. It’s interesting to note that BuySnus.com calls this a “Soft White Dry Portion”, which to my memory is the first time I’ve seen that phrasing used.
SISU is an interesting product. In terms of taste, it's a solid flavor. It doesn't stand out, by any means, but it does have a nice taste to it. The best part about this product, in my opinion, is the portion material. It does not feel like a white dry product. If you're a fan of mint snus, I'd definitely suggest giving this one a try!
