While we can't make claims it was produced from sap out of our trees, nor that we boiled it at our farm, we did put it through numerous rigorous steps to insure the same quality you'd expect of our own syrup. Indeed most of the labor involved with preparing our syrup for sale is after it’s boiled, with the filtering & bottling process. Axel delivered the syrup we’re offering in numbered barrels along with small, sample bottles, which were numbered to match. We first signed off on all the samples before accepting delivery. Next, we ran the syrup through a filter press to get out most of the impurities, and then filtered it once more as it was pumped into a 'finisher'. We heated it to 180 degrees Fahrenheit and bottled it, after which we labeled each bottle. This entire process was done entirely on our farm, all by hand, which is extremely labor intensive and time consuming. We of course tested the syrup as we processed each barrel, tracking it back to the original sample to make sure it matched the sample and that the quality lived up to our standards. We can't make claims to doing a blind tasting, comparing it to the syrup we boiled, but honestly we suspect we'd be hard pressed to say which is better, it's that good. Like with our own syrup, we guarantee complete satisfaction. If for any reason you're not happy with it, you can return it for a 100% refund.
