Overview

Producers in most regions had minor to very good sap flows between the 3rd to the 8th. Some producers in colder regions, such as Algonquin and Algoma, seemed to have better flows on the weekend. The majority of syrup made was golden and amber, although lots of dark syrup was made in Simcoe & district. Flavour was generally good, although a couple producers noticed a slight metabolic off-flavour. Some producers noted lots of niter and others had a hard time filtering, but the two weren’t always associated. Snow cover was significantly reduced in many bushes, although most had decent amounts of snow left.

Southwestern (4 – number of respondents)

There were very good sap runs in the past week, with reports of sap flowing for 4-7 days, sometimes at 24 hours per day. Some were shocked to see it run so long without a frost. Sap brix ranged from 2.0 – 2.2. Golden, amber and dark syrup were all made. Filtering was good for the most part, but there were some struggles. Producers have made between 0.3 – 1.3L/tap so far, representing 30 – 98% of their average crop.

Grey-Bruce & District (6)

Producers noted small to mediocre sap flow events. Sap flow was best when nighttime temperatures dropped below -4 C. Sap brix ranged from 2 – 2.8. For those who boiled, both golden and amber syrup was made with good flavour. Once producer noted challenges filtering high amounts of nitre with a filter press. Producers have made between 0.3-0.4 L/tap representing 15-20% of their average crop. Although snow cover was reduced significantly, producers noted good amounts of snow still left in the bush. One producer noted lots of spongy moth egg masses on trees.

Waterloo-Wellington (8)

Producers noted small – good sap runs over the past week. A big flow was noted after the warm up, with slow and steady production with the vacuum running. Sap brix ranged from 1.7 – 2.3. Producers made both golden and amber syrup with good flavour. Most producers had no problems filtering, although one noted niter was very fine and hard to filter out. Producers have made between 0.38 – 0.5 L/tap, representing about 20-30% of their average crop. Producers note a lot of the snow is gone from the bush, but some still remains.

Simcoe & District (12)

Producers noted some good days and some slow days. Sap brix ranged from 1.5 – 2.6. Both amber and dark syrup was made, but most producers seem to have made dark. One producer noted some light metabolic off flavours. Between 0.13 – 0.5 L/tap has been made so far, representing 3-25% of an average years crop. Producers note a decent amount of snow in the bush still after the thaws.

Algoma (2)

One producer experienced fantastic flow and the other only minor flows over a 72 hour period. One producer made syrup while the other froze sap to cool later sap runs. Sap brix was between 1 – 2.2%. Dark syrup was made with great flavour. Filtering syrup was very difficult despite no noticeable sugar sand. 0.15 L/tap was made representing 15% of an average crop. Squirrel chews were noted.

Algonquin & District (12)

Producers noted small – good sap flows, although most producers had good runs. Sap brix ranged from 1.2 – 2. Many folks were not done boiling by the time they responded to the survey, but those who had finished a batch made amber syrup. One producer noted a slight metabolic flavour. One producer noted there was lots of animal chewing damage from various animals. Many producers noted lots of snow melting in the bush, but there is enough to make working in the bush unpleasant. One producer noted how trees with 4-5 ft of snow weren’t flowing, whereas those with less snow were.

Haliburton-Kawartha (9)

Low to moderate flows were noted, perhaps due to temperatures being too warm at night. Sap brix ranged from 2 – 2.5. Golden, amber and dark syrup were all made, all with good flavour. One producer noted syrup was very difficult to filter, another noted the niter was black and gooey. Between 0.06 – 0.15 L/tap has been made so far, representing 5 – 12% of an average crop. Lots of snow melted, but there is still a decent amount in the bush. The warm temperatures have allowed some to improve their vacuum levels significantly.

Ottawa Valley District (2)

Tapping is still in progress. Minimal sap flow was noted despite warmer temperatures.

Quinte & District (7)

Small to great sap flows were noted from the 3rd to the 7th. Sab brix ranged from 1.8 – 2.8. Some noticed sap brix decreased as the temperature got warmer. Both Golden and amber syrup was made, with good flavour. One producer noted that the past couple boils have been hard to filter, but others experienced no problems despite higher levels of sugar sand. The difficult-filtering syrup was noted to have a slimy texture, somewhat like ropey. Between 0.2 – 1.25 L/tap has been reported so far, or, between 5-30% of an average years crop. Some producers have lost all their snow, while some still have a decent amount in the bush.

Lanark & District (8)

Most producers experienced small sap flows, although some had moderate flows. Sap brix was between 2 – 2.4. Only one producer has made syrup so far and they made 0.1 L/tap of Amber syrup, representing about 10% of their average crop.

Eastern (9)

Some producers noted only minor flows while others noted some good flows. Sap brix was between 1.8 – 2.2. Both golden and amber syrup was made. Those who have made syrup have only produced about 5% of their average crop so far.

Overview

Producers across much of the province noted at least some sap flowing on the 27th and 28th. Most areas experienced minimal flows, but nearly all producers in Southwestern and some producers in Waterloo-Wellington, Quinte and Simcoe experienced good flows. Both golden and amber syrup was made, generally with good flavour and no processing issues.

Southwestern (4 – number of respondents)

Respondents indicate there was at least one good sap run in the past week, on the 27th – 28th, with sap brix of about 1.6 to 2.1. Both golden and amber syrup was made, with good flavour. One producer observed lots of niter, but syrup was easy to filter. Producers have made 0.4 – 0.6 L per tap so far, representing 20 – 45% of an average crop.

Grey-Bruce & District (6)

Producers noted some small sap flow events. Most producers haven’t boiled yet, but one made about 0.1 L/tap of amber syrup, representing about 4% of their average crop.

Waterloo-Wellington (6)

Most producers are fully tapped now. Some producers noted some good runs, on the 27th – 28th, and others experienced little to no sap flowing. Producers made golden and amber syrup with good flavour from sap with 1.5 to 2.2 brix. Producers have made between 0.17 – 0.5 L/tap representing 10 – 25% of their average crop. One producer noted they had a hard time filtering syrup.

Simcoe & District (8)

Some producers experienced one good flow, but most experienced little sap flow. Those who boiled produced both golden and amber syrup from sap of 2.4-2.6 brix, representing about 5% of their average crop. One of the producers noted a sharp woody taste in their first batch of syrup, which could be metabolism.

Algoma (4)

All respondents were fully tapped, but sap isn’t flowing yet.

Algonquin & District (9)

Large producers (8,000 +) have all or nearly all their taps in, but have reported no significant sap flows. producers between 1,000 to 2,000 taps are still tapping. Most producers under 1,000 taps are likely to start tapping this week.

Haliburton-Kawartha (7)

Not all respondents are fully tapped yet. A minor sap run was noted and one producer made good flavoured amber syrup from 2 brix sap, totaling 0.1 L/tap so far.

Ottawa Valley District (2)

Tapping is still in progress. Minimal sap flow was noted, not enough to flush the lines.

Quinte & District (6)

Most respondents are fully tapped. Some producers noted only small flows, but others experienced larger flows, particularly on the 27th and 28th. Sap brix was recorded at 1.5 and 2.6. One producer made golden syrup with great flavour and has now made about 0.24 L/tap, about 12% of their average yield. It was noted that a lot of energy is being used to keep buildings warm between sap runs.

Lanark & District (7)

Most producers are fully tapped. Some experienced a small run of 1.8 brix sap on the 28th, but not enough to boil.

Eastern (6)

A couple producers experienced very light sap runs one day, maybe just enough to flush lines.

Overview

Producers in some of the southern regions of the province have gotten some decent flows and have begun to make syrup. Most producers got sap brix of around 2 and made golden syrup, although some made Amber. Syrup generally had good flavour. Producers in colder regions experienced negligible or no sap flow events. Many producers continue to note that deep snow is making things tough out in the bush.

Southwestern (8 – number of respondents)

All respondents had all their taps in. Most producers experienced moderate to great sap flows until the cold returned, with average sap brix ranging from 1.8 to 2.1. Most producers made golden syrup, with a couple making amber. Flavour was generally good. Most producers have made between 10-30% of an average years crop so far, reporting between 0.1 – 0.35 L/tap. One producer reported outstanding yields, 50% of their average crop with 1.5 L/tap, from 3.5 brix sap. One producer noted lots of niter, another noted the first run of sap was cloudy before boiling, and another noted that the first boil flavour was only okay.

Grey-Bruce & District (3)

All respondents had all their taps in. A minor sap flow was noted, just enough to flush the lines for some and enough to boil for one producer. That producer made golden syrup from 1.9 brix sap, about 2.5% of their average crop. Flavour was good.

Waterloo-Wellington (4)

Half of the respondents are fully or nearly fully tapped, and half have not started tapping. Minor to good flows were reported. One producer made amber syrup from 1.8 brix sap, about 5% of their average crop at 0.1 L/tap.

Algoma (2)

One producer with about 70% of their taps in noted that some sap was flowing with vacuum on, but not without vacuum. The other producers plans to begin tapping soon.

Algonquin & District (12)

Large producers (8,000 +) have all or nearly all their taps in, but have reported no sap flows.

Haliburton-Kawartha (8)

Ottawa Valley District (3)

One producer is fully tapped and has recorded no sap flows.

Quinte & District (5)

A larger producer (approx 8,000 taps) is fully tapped and made about 5% of their average crop so far from 11000 gallons of 2.5 brix sap. That translates to about 0.1 L/tap so far. Syrup was golden and had excellent flavour.

Overview

There were 39 responses to the survey in total. About half the respondents have less then 1,000 taps, with the other half having between 1,000 – 10,000 taps. The majority of producers have not begun tapping. Many producers noted the deep snow cover in their bush, making operations difficult. Some producers in the Southwestern and Waterloo-Wellington region are thinking of tapping soon, depending on the weather.

Overview

Sap flow has been sporadic in most regions over the past week as warmer weather moved in and many producers have noted that they are 2-3 weeks ahead of their typical season. There have also been quite a few comments on a significant drop in Brix levels from the previous week, which is not uncommon to occur in warmer weather conditions.

Thank you again for all your responses to the survey! And best of luck in the rest of the season! It’s been great working with all of you 🙂

Overview

As we enter March, the season continues to be unpredictable and inconsistent with big temperature swings that have impacted sap flow in a number of areas of the province. There have been many reports of snow melting, mud, and/or dry conditions in woodlots. In the south, there have also been signs of budding in soft maple.

In terms of clarity and filtration, there continues to be minimal issues among most survey respondents. Producers in the southwestern region are starting to wrap up for the season while those in the eastern and northern regions starting to ramp up.

On another note, it is with mixed emotions that I share that next week will be my final Sap Flow Report as I move on to new opportunities – however! The report will continue in my absence for the remainder of the season. It’s been wonderful working with and getting to know you all over the season. All the best going forward!

If you have any comments on how the survey or report can be improved upon, please feel free to send me an email at sophie.krolikowski@ontario.ca

Thank you again for all your responses to the survey! It’s been a blast!
